If you have vehicle electrical problems of any level of difficulty. Jerry is definitely an exceptionally person for the job. When Others couldnt track down the problem. Jerry, while keeping me informed went step by step, diagnosed and repaired my initial problem. Found a secondary issue and gave me a course of action. Great service and attention to detail. Im truly grateful.

This review is coming a year later. My 2011 Accord had drl issues. Dealer didnt want even try looking at it. These guys fixed the issue. A year later no problems.

The mechanic was honest and fair. He saved me over a grand. If you ever have any electrical problems, never, ever take it anywhere but here. It’s 100% worth it.

Jerry & Jim are outstanding electrical diagnoses. I had an issue with my 97 Dodge Dakota for 13 years! Jerry Finally found the issue. Took him a while to find it, but he did & fixed it right! The price for the job was very reasonable. I wish I would have known able hi,m many years ago. They gave me outstanding service, great pricing, & best of all he fixed the problem Highly recommend these people for automotive electrical repair.

Jerry is the man—confident in his ability to find the problem and fix it. Did some clean up work on my 1970 Buick. He keeps you up to speed on any issues he finds and his overall progress. He said to me, “your car’s good, but it can be great”.My type of shop.

Ive had an intermittent no-start issue with my Chevy Aveo for a few years now. No one could find the problem, even the dealership! Jerry at Keystone was able to find the problem. He called and kept in touch while he had my car, Jerry promised he would find the problem and fix my car! And he delivered on that promise.He is qualified with expertise in electrical issues, but also has an intuitive talent for finding the source of elusive problems. Im thrilled! Highly recommend you call about your tricky electrical mystery.

I have a 1971 Plymouth Barracuda that has had electrical issues for a while and my mechanic couldnt figure it out after several attempts. Turn signals and brake lights werent working, bulbs were burning out, the car was stalling and the headlights were dimming at idle. I brought the car in and within a few days, Jerry diagnosed and fixed the issue. Ive had no problems since and it runs great! I highly recommend Keystone to anyone having any kind of electronic issue. I just wish I had brought it to Keystone earlier!

BEST customer service Ive ever experienced from an auto shop. Not an exaggeration! Jerry tackled my electrical problem and got my 16 Camaro SS back up and running. He continuously kept in contact with me on the progress of my vehicle. He asked detailed questions to get down to the root of the issue. He genuinely cared about my vehicle and getting it to perform the way it needed to be. He also showed concern with pricing and keeping me on budget. You wont regret taking your vehicle!

I had been having an intermittent starting problem for a few years with my 1972 Oldsmobile Cutlass with LS1 engine swap. Took car back to original installer of motor and they could not find problem after several attempts. Found out about Keystone after quick Google search for automotive electrical experts in Philadelphia area. Called Jerry and he spent several minutes with me on phone to run some quick diagnostics and ask several questions. After a few simple ideas that did not work I brought car over. Jerry was methodical, very detail oriented and would not give up until he found the problem (2 separate issues actually). Both related to bad connectors which I would have never found on my own. When finished he spent much time explaining his process of diagnosis and repair. Jerry is a true professional and I admire his intelligence and organized approach to researching and repairing these complex problems. I will definitely take any vehicle back to him in future if ever needed. One happy customer!

Jerry and Jim at Keystone Auto Electrical are knowledgeable, trustworthy, and thorough. They fill a critical space within the field of automotive electrical repair.At the beginning of a trip to New England, our Subaru Outback suddenly shut down. We had it towed to a nearby dealer who did simple diagnostics showing the ignition coil fuse was repeatedly blowing. After replacing the fuse multiple times and the problem ceasing, the vehicle was returned to us thinking that the problem was fixed. One day after receipt from the dealer, the problem resumed. Not knowing where to go, we decided to try Keystone based on the information provided on their website and other Google reviews.The problem was truly intermittent and difficult to reproduce. Because of this, it took some time to find its source. Nonetheless, Jim and Jerry stuck with the project and communicated appropriately with me throughout the time the vehicle was with them. Ultimately, the source of the issue was found to be a short in the wiring harness requiring a small repair and increased insulation. This was in stark contrast to other suggestions that we should replace the alternator or ignition coil pack, which would have added significant cost and not solved the problem.In all, Keystone has fair pricing, they are honest, and they treat your vehicle with care and as their own. It may take time, but you will leave Keystone knowing that the problem was solved.

This guy is super helpful if you have electrical issues with car go see him he will literally apply every ounce of his individual knowledge and his prices are good

Great honest place, highly professional, and experienced.My Nissan was having an electrical problem, causing a security code that would prevent the car from starting. I took it to the local dealership, and they were unable fix the car, only charge me for unnecessary parts.I should have brought my car to Keystone first. They diagnosed the problem and fixed it accordingly. Jerry returned calls, and gave updates. I would return to Keystone if needed, and I highly recommend them to anyone requiring an auto-electric pro. Thank you Jerry and team Keystone.

I had a problem with this truck 2008 Dodge Durango for almost a year before meeting Jerry at Keystone Electric he gave me great advice and then also did the repair on my truck and I couldn’t be happier. I have been to the dealer and several other shops that all were a waste of time I wish I had found them sooner trust me you won’t be disappointed at the end of the day we all want our cars to be serviced by a professional that actually completes and get the job done correctly and that’s what I feel like I received thanks guys for doing a great job and I’ll refer you to any friend that has a problem

Great doing business with you guys. Hope to hear from you again in future.

Excellent service and knowledgeable staff

I was at the Nebraska State Fair and left to go home on Labor Day night. When I reached Illinois, my Honda Odyssey minivan died mysteriously. I had it towed a total of seven times, including two Honda dealerships. It was determined that the IGN COIL 15 amp fuse kept blowing intermittently, but no one could find the source. Well, I was stuck in 4 states. It took me 5 days to get home when it would have been 1. This is an experience that I would like to forget.Somewhere during the end of this ordeal, I found Keystone Auto Electrical and talked with Jerry. He asked me specific questions and I answered them. Even though he needed the vehicle to identify and resolve the problem, he exercised extreme patience over the phone. He truly cared about my situation and spent much time to help me.Keystone Auto Electrical found the problem in a day. This is quite impressive because nobody had a clue. This place has decades of experience and truly finds and solves all auto electrical issues. Their shop is extremely clean. I highly recommend Keystone Auto Electrical to anyone!!! You’ve earned my confidence!Jerry, thank you so much for your professionalism, expertise and kindness! I am very grateful to have met you—you’re truly exceptional! May God bless you always.

I never post reviews. Jerry is the first person to motivate me to post a review like this.The world needs more people like Jerry! He is knowledgeable, exacting, generous with both his time and knowledge, very professional and trustworthy.I have a 2004 Acura MDX that the blower motor burned out on because of leaf and debris buildup in the blower motor fan. What should have been a simple fix turned into a more complicated issue than it should have, partly because of me. Jerry asked a number of questions and unraveled the problem in a couple of hours! Most impressive! And last but not least his pricing was fair and reasonable.I would recommend Jerry as thee only guy to go too with automotive electrical issues.Bob

Jerry’s customer service is beyond amazing!! I have never had a more pleasant experience with getting my car fixed! A family member gave me the number and said “you’re crazy if you go anywhere else,” and I agree wholeheartedly! Quick, efficient, and cost effective. A/C or electric problems, Jerry is the only one you should call!

Several years ago owned an Explorer with speedometer problems. Took it to Brian Hoskins Ford only to get ripped off. Two weeks later and over $1000 in charges the problem persisted. All they did was throw parts at it and charge me. In steps Jerry from Keystone. Within hours he had it diagnosed and fixed. Had nothing to do with any parts Hoskins installed.Fast forward to today and my F150 with a blown radio. Once again Jerry fixed the problem with no run around. Jerrys 100% honest and fair with prices. You can count on your problems being fixed with no surprises in price increases.

I will DEFINITELY RECOMMEND THIS PLACE...EXCELLENT SERVICE..IF YOU NEED ANY ELECTRICAL SERVICE PLEASE UTILIZE THIS BUSINESS AS I WILL FROM THIS POINT ON.

Absolutely the best mechanic I’ve had to ever work with . I had taken my 2008 vw to multiple experience mechanics who couldn’t figure out what was wrong for months (parasitic power draw) . Gerry at Keystone took over 30mins to hear my compete car history and absolutely every detail I could provide before even asking me to bring the car over . After fixing what I thought was an impossible repair . He went ahead a fixed some miscellaneous problems as well !

These guys are the best. Diagnose. Pinpoint. Fix. What else can you ask for? Thank you for the realistic composition and expectations of your work. Owner of a Subaru 2007 Outback 2.5 Basic.

Totally professional craftsmen. So pleased with the diagnostics that I returned a week later for the fitting of another part sourced elsewhere. A rare gem of a place where they know their subject thoroughly. The work is completed in good time and the charges are reasonable. If you have a really difficult / impossible problem a regular mechanic cannot fix, the chances are Keystone will be able to.

Wow are we glad we were referred to this shop! Jerry is the best- honest & caring. Keystone Auto Electrical will fix the problem & not rip you off. We now live over an hour away & still come to Jerry if we have electrical issues with our cars... yes, he’s that good.

LIFESAVER! I MADE THE MISTAKE OF BUYING A POLICE DODGE CHARGER. THE WIRING WAS HORRIFIC. MY WINDOWS DIDNT WORK, THE TRUNK AS WELL AS MY PUSH TO START WERE NOT WORKING. NO ONE WOULD GIVE ME THE TIME OF DAY. JERRY AT KEYSTONE ELECTRICAL WAS EXTREMELY KIND AND SOLVED ALL THE ISSUES I HAD. NOW I HAVE A FULLY FUNCTIONAL DODGE CHARGER. YOU WOULDNT EVEN KNOW THAT THERE WAS ANY ISSUES. JERRY THANK-YOU SO MUCH! HE IS THE ELECTRICAL GURU!

After having another shop look at my air conditioning problem I waslucky to be referred to Keystone Auto Electric. As soon as I met Jerry, Iknew he was a straight shooter, no BS kind of guy.After checking out my complicated situation, Jerry called to say thecost of the repairs would be very, very expensive. Since my 2010 FordTaurus has over 225,000 miles on it, I decided to pass on getting it repaired.In the meantime Jerry put on his creative cap, found a solution that wouldwork and saved me hundreds of dollars. Im grateful to have found a personable, honest businessman.I highly recommend KEYSTONE AUTO ELECTRIC. Terrific communicationand service. FIVE STARS !!! Ed Thornton, Wynnewood, PA

Keystone is the very best. I drove 5 - 6 hours round trip from North Jersey to Pa to have Keystone fix my car. Two years ago the spoiler bar wouldn’t go down on my car and something was causing a battery drain. Two batteries later I took it to my mechanic who couldn’t find the problem. I took it to the dealership. Three days later and a good amount of money they said “we don’t know why, but if you take the light out of the trunk the drain stops and the bar goes down”. Enough money spent so I left it like that. But when it rained the ABS brake system lights and brake lights would go on. About 4 months ago the driver’s side window wouldn’t go up. I found that if I hit a bump hard enough the window would go back up again. If I hit a bump again the window wouldn’t go up and so back and forth it went. I am not kidding, I literally had to speed into potholes to get the window up, it was insane. Took it to my mechanic who said it was an electrical problem and wires in the dashboard were crossing and coming apart when I hit a bump, he wanted to take off the dashoard. I knew the problem was past him and the dealership wasn’t good either. Then the battery drain and bar problem came back, the doors wouldn’t lock, you couldn’t move the seats, the convertible top didn’t work, everything electrical stopped working. ABS brake light system and brake lights were on all the time. I knew I desperately needed a top notch electrical mechanic. I needed someone who did electrical problems only. Keystone was that place. It was the best thing I could have done. Jerry was great, he is detailed, logical, competent and he took the time to really investigate. He asked me questions followed the circuits, asked questions and always let me know exactly what was going on financially. I always knew exactly where I stood. Jerry found the problem. An electrical connector in the back wheel area was out of place and would get wet. As corrosion got worse so did the car. Jerry is a great detective. My car is working great. It was well worth the trip and I don’t think I will ever go to anyone else, they are that good.Deborah S.

I very highly recommend Keystone Auto to friends, family and strangers! Jerry performed a thorough diagnostic on my truck, eliminated the potential variables that may have caused the issue and very clearly communicated his diagnostics. He not only helped to fix the issue (continually blown fuse for O2 sensor heater) he educated me along the way and as an at home hobby-ist mechanic that was extremely helpful and greatly appreciated.I drove over an hour to take my truck here and after the professional and courteous service they provided I would have driven 10. This is an honest shop with honest people and great service. You dont find shops like this very often.Thank you again, Jerry!!

Dont go to a regular repair shop if you have auto electrical issues. Go to Keystone. Theyre the best.Keystone has handled all of my auto electrical needs for over 10 years and their work is impeccable. Theyve diagnosed challenging issues and done the required repairs quickly and thoroughly, saving me thousands of dollars in the process.

This shop is a treasure. I drove almost an hour each way to get there, and it was worth every second. Jerry is a diagnostic genius (hes since helped me solve a lighting problem over the phone), is honest, clearly loves his work. He installed fog lamps for me, which the dealer said could not be done, and they look and work like factory installed. Whatever your car electrical problem is, this is the place and the man to solve it.

Usually I dont write reviews but these guys are just that awesome. Its an honest shop and they do great work with excellent communication. I brought a 1969 Ford F-100 to them and they took care of my electrical issues quickly and effectively. I would recommend them to anyone. Thanks!

No need to take your car anywhere else but here if you’re experiencing electrical issues. Jerry is very professional and talked me through every possible scenario. No need to take your car anywhere else but here. Very Happy with the octcome.

Ive been calling on Jerry and his staff for over a decade. Always friendly, and helpful, I never hesitate to reach out when a technical question or concern is over and above my talent level, or the knowledge of my own automotive staff. I used to operate a service shop near keystone, and would send customers to Jerry if it was out of my expertise. A few years back, I relocated further away. I recently had a electrical headache in my shop, and Jerry remembered me, took the time to walk me thru the pinpoint test over the phone, exceptional care, exceptional service!

Great place, thrust worthy people

The engine harness of our Acura MDX had been completely gnawed by mice in multiple locations. It was quite depressing looking at the engine. Everyone I called in the area either said the entire engine harness would need to be replaced ($$$$) or they would not take on such an ambitious repair. That was until I was referred to Jerry. Jerry reassured me on the phone that he could repair the car with confidence. So the car was towed to Keystone. Within a week, the MDX was repaired and Jerry ensured that it passed all the diagnostic and road tests before he handed over the keys.From the time I dropped off the MDX and picked it up, I knew the vehicle was in the best possible hands for the type of electrical repair it needed. Jerry is a true practitioner of bespoke auto electrical repair work. The engine harness was repaired in the most professional manner saving me $$$$ from having the entire engine harness replaced. Jerry even checked the interior wiring of the car to ensure everything was fine and the damage was confined only to the engine. Jerry has earned my patronage moving forward for all my auto electrical needs no matter how small or large. Personally, having Jerry take care of my vehicles is a peace of mind that I cannot quantify.-Tony P

I recently had my Chevy Suburban in at Keystone to fix an airbag error light that kept coming on. Jerry was very helpful and was able to trace it to a wire that had come loose - no need to replace the airbags! I loved the fact that Jerry took the time to research and diagnose the problem first rather than just starting to swap expensive items out (in my experience, the usual dealer approach). I would happily recommend Keystone for anyone with electrical problems with their vehicles. I am a very satisfied client.

Im a big fan of Jerry and Keystone Auto Electric. Hes a great troubleshooter, and an even better communicator.Id recommend him to anyone.

We all have car trouble at some point in our lives. Wouldnt it be nice to know that there is still a place you can go where the mechanics genuinely care about you and your problem? At Keystone Auto Electrical they represent the best in customer service, automotive knowledge and true passion about their business.I had electric issues with my Cadillac Escalade. After multiple trips to the dealer, I was left with a huge repair bill that did not fix the problem and was basically told, You should just get rid of this vehicle.I called Jerry and he said, Bring your truck down and we will figure it out.The very first thing I noticed is that the guys at Keystone go over your symptoms and driving habits before they troubleshoot, not only to save you money, but to get to the heart of the problem. Jerry would always call me every few days to let me know what he found out and which options were available. Before he made the repair he explained to me what was causing the problem and why the problem had occurred. Jerry even told me that he could get working used parts to save me money. I really appreciated that.I drove nearly 50 miles over an hour from my home to see Keystone and it was worth it. I would have driven even further for the service and results I have received from these guys. My truck has a new life and I am a happier person.Keystone Auto Electric is awesome. I will recommend them to everyone and always go to them first in the future.

Jerry is a great electrician, easy to work with, and was able to solve my electrical problems in a timely and cost-efficient manner. The car that I brought to him wasnt easy either...its an older Frankenstein project that has a less than perfect wiring configuration. I wouldnt hesitate to go back....In fact, I just recently did.

The only thing possibly better than taking my car to Jerry, would be to actually have Click and Clack (the Tappet Brother of Car Talk) work on my car in person. Great experience from beginning to end!

I have a 1985 Jeep CJ7 with a 92 chevy V8. Any normal “chain store” auto mechanic won’t even talk to me, and the few times I have left it with a mechanic I received a big bill and no help.I found Keystone Auto Electrical after 6 months of unsuccessfully replacing parts. It took only a day and a half for Jerry to find the issue and fix it. My Jeep has literally never run as good as it does now. But that’s how every thing ended up. How we started, that was what I found most impressive. Jerry spent at least 15 minutes on the phone with me the very first time I called and walked through what parts were in it, what symptoms I was having, and what I had replaced. He offered trouble shooting suggestions without even seeing my Jeep for free over the phone. That was when I realized I had finally found an honest mechanic. I’ve talked to other places that immediately reply with “sure just tow it in” just because they are happy to bill me for absolutely everything. I found the cost of their work totally reasonable and would do it again in a heartbeat.This is the shop you’ve been looking for.

I cold called Keystone to help me solve an electrical issue with my ABS and talked to Jim. I worked on the problem for weeks and finally was going to throw in the towel when Jim started to ask me diagnostic questions in an effort to help me get back on track. I was surprised by Jims willingness to help me. After a 25 minute conversation Jim pointed out some of my testing deficiencies which I in turn used to repair the van. It took 1 hr for me to solve the problem after Jims help. I called back to thank him. He said he was happy he was able to help me fix my Van. Then a week later Jerry called me back to thank me for calling back to report my progress. They earned no money from me to date. Their entire motivation was to help a fellow knuckle buster solve their problem. No trade secrets with these Guys. I have been in business for 30 years and have helped people out the exact same way. I figured that the good will was good word of mouth and would translate into future sales. Honest competent businessmen rely on their good work to generate income and do not need to generate sales by keeping their knowledge secret. They are proud and enjoy sharing their knowledge. My experience with them has revealed that they conduct business using the same philosophy. West Chester should cherish Keystone Electrical as an asset to their community. Hopefully Jerry will call me at the Irish festival and take me up on my offer to buy him a beer. Tom B

My husband and I were moving and had trouble with the trailer we rented-- the electrical system in our car wouldnt hook up correctly, so the turn signals on the trailer werent working--we had 3 pick-ups of furniture scheduled that day and were in a total panic. On the recommendation of a person at Firestone, I called Jerry at Keystone Auto Electric. He asked about the problem, and had my husband -- who was with the trailer--call him. He walked my husband through fixing it on the phone, so we didnt even need to bring the car in! There was no charge, but rest assured, if we ever have another electrical problem with the car, Jerry will be the first person we call. He was prompt, kind, and incredibly helpful.

Jerry and Jim offer very personalized service and care about their customers. They fixed a difficult parasitic drain problem with my Corvette and followed up to make sure everything was ok. Highly recommended.

Jerry is the kind of mechanic that doesnt exist anymore...an honest competent one.I originally called him because of issues with my AC, he diagnosed that it wasnt a bad relay, and that it was the AC compressor. Instead of charging me an arm and a leg to replace it, he said I could install it myself and bring it back to him in order to save about $700. He was even kind enough to help me through the process. He then vacuumed and re-charged my AC system and it works perfect. In the end he saved me about $700-$800 just for being honest. On top of being a great mechanic, he is an extremely friendly guy who realizes customer service comes first.If you have any issues with your vehicle, go to Keystone Auto Electrical first and you may end up saving a lot of money. I would highly recommend them for any electrical or A/C issues on any vehicle.

Kept truck for two days, checked out headlights. Charged me for an hour time. I never checked them there, but next day same problem. Charged me over $70.

I contacted Jerry on a referral from another garage to ask him about an old Magneto for a Chevy 409 engine. Jerry was more then happy to take a look at it for me to see if it was a working Magneto, or just reduced to a piece of industrial art. While there, we started talking about art, and we found a mutual respect for one anothers craftsmanship. Jerry and his crew really know their craft, and if you ever need electrical work done on your car, THIS IS THE PLACE TO GO!! Do not deal with small time garages or auto dealerships that will cost you an arm and a leg... and still not get the job done. Get it done right the first time! Go see Jerry and his crew, you will be glad you did! Thank you Jerry for your time and your hospitality. Im looking forward to seeing you at my shop in Downingtown soon!-Greg

A super experience. Diagnosing automobile electrical problems can be QUITE challenging. IMO, the team at Keystone is up to the task! I have a 2009 Acura MDX that had been running great until a system in the SUV began draining the battery. The battery would go dead in about 24 hours. The team located the problem and fixed it. The MDX is running great again. The team at Keystone is flexible and responsive. They even let me keep my SUV parked on their premises for about a week until I could make arrangements to pick it up. Also, the MDX was well taken care of, while it was with them (ie no door dings or scratches). I recommend them highly. They were recommended to me by one of my local auto mechanics, and I can see why.

Several years ago I had an automatic window drop and a persistent check engine light on my 2003 Dodge Caravan. Took it to Jerry at Keystone and he solved everything. So when I had another check-engine light come on this year, I didnt hesitate and took the van back to Keystone. And once again Jerry worked his magic, solved the problem, and even called a couple weeks later to see how the van was working. Top notch work; reasonable price; and youll feel certain that they will solve your problem the first time.Whenever a friend or neighbor mentions having any electrical problems with their vehicles I always refer them to Keystone! You wont be disappointed!

There have been two occasions within the past couple of years involving an AC issue and a Battery Draining/Dying issue. On the AC issue, a local auto dealer wanted to charge around $1400 to fix what turned out (after Jerry checked it out) to be a non issue only requiring recharging the system. After two years the AC is still working perfectly. Jerrys charge to find and fix this non broken problem was about 10% of what the Ford dealer wanted. Today I took my car over because the battery was draining/dying. Jerry checked the system and found that apparently the battery connections were loose, which was my fault as I had recently changed a battery and apparently failed to tighten the cables properly. His charge was a handshake. Its great knowing that there is an auto repair facility where you can trust the advice, the repairs, and the price charged. J. Moeller, W.C.

Jerry has impeccable customer service skills and patience he also treated me with respect and I greatly appreciated it. I can not say enough to express how awesome Jerry is. I am mechanically inclined but not a mechanic. I had an issue with my car dying while driving. Pulled the battery took to adv auto tested fine, pulled alternator 2x and passed bench test. After hours of sweating and aggravation I happened across this place on Google. I called in desperation as I am single father and this is my only vehicle and my finances severely limited. It was like 15 min to close Jerry Took the time to walk me through several voltmeter test asked me to call him next day . I called and he took the time to listen to my results and give me his professional adv take my alternator to be tested elsewhere, which I did and was told it wouldnt charge a 9v battery. I promised a glowing review for his efforts.

I have a 96 Acura Integra that lost all of the gauges ( MPH, Rpm,hot cold, gas, and clock)Had 3 shops look at it and tell me they had no idea what it could be, guy from shop told me too call jerry and Jim at Keystone they would know . Drop it off to them next Day its fixed and on the road . These guys know there stuff and make you feel right at home . Great price great guys, thank you so much Jerry and Jim I know who too call for now onEdgar B. Melton

Jerry is great. I would highly recommend Keystone Electrical to anyone..Thank you.

Very good and quick work. Had my problem diagnosed in hours. 5/5 would recommend to anyone.

These guys are excellent professionals and provide top notch customer service!

Jerry at keystone made me feel at ease within minutes of talking with him about my starting issues with my 71 chevvelle dropped it off jerry and his team took care of the problems I now for once in 2 yrs have the confidence to get in my chevelle knowing it will start not only that it was my birthday on a nice weekend and did not have a ride to pick up my chevelle jerry came and picked me up at my work. great job jerry and jim at keystone would highly recommend to all thanks Charlie coatesville

I have a 2002 Subura Forester in which I have been battling the catalyst converter (p0420 code) for about a year. No one knew (auto body shop and dealership) what was wrong with the converter, they kept giving me the run around and pointing fingers at each other. Ive had the converter swapped 3xs(because they were the ones who change it in the first place and no one else would touch it because of that), O2 sensors and the air/fuel sensor done with the auto body shop and i kept getting that check engine light with the same code (pO420).Well, I called Jerry (Keystone Auto) explained all that i have gone through and if he would have any suggestions. After he listedened Jerry explained to me the LIFE of a (my) auto exhaust. I took that information back to the auto shop where I got the work done and told them exactly what Jerry said, the auto shop AGAIN swapped the converter to a different one (which had 2 cats, the pre and the cat). And BEHOLD, 140 miles later NO CHECK ENGINE LIGHT (in which before i only got to 25 miles before the light came back on).Viewers and Reviewers, these guys are not Auto Doctors as some has called them, they (Jerry) are SURGEONS!!! Not only did Jerry diagnosed my car he CURED my car with one phone call. My hat is off ....they get a 5 star here but in my eyes they get a 10+ stars....We need more auto shops like them.

Best electrical diagnosis garage for many years.

Very honest and professional so complicated was my car issue and it got fixed very professionally and with no time

They took my problem on after 2 shops could not repair my suburban Jerry made my suburban usable and trustworthy Thanks again

Very honest technicians, hard to find!!

Jerry is the Best!!!!! I highly recommend Keystone Auto Electrical.

Can solve complex auto electrical problems well.

The owner is a rip off artist steer clear of Keystone Auto Electrical...
