We started in 1979 rebuilding rotating electrical parts (alternators & starters) for sale to the trade. We soon realized the opportunity in diagnosing and repairing complex electrical problems, and continued focusing our efforts to that end.

Jerry did an excellent job fixing a very odd electrical problem in our Honda Civic. He is very easy to talk to and continuously keeps you in the loop while he is diagnosing whatever the problem may be. It certainly wasn't an easy job, but he got to the bottom of it and now we have working AC just in time for hot summer weather! I could not be happier with this man's work. -Joe C

Had a problem with the convertible top on 64 t-bird. Took it to Jerry and he was able to fix the problems with the top. Can't say enough about the great work that this company performs. Thanks, Service: Electrical

Jerry is a deeply analytical man who solves problems others cannot. I've used him on more than one occasion to resolve issues that other said were "unresolvable". He is efficient, communicates well, and not overly expensive for the type of work he does. A true win-win-win. I would enthusiastically recommend Keystone auto electrical without compunction or reservation. I don't believe there is anyone else doing this very specialized thing, with such skill. Plus he's a nice guy!

I was upgrading my interior lights to LED on my 2022 Tacoma and blew a fuse. I was having a hard time finding the correct fuse and the Toyota dealership want to charge me $100 just to take a diagnostic. I called Jerry and within 5 minutes he found the bad fuse and fixed it a no charge. All my interior lights are now working and I would recommend Keystone Auto Electrical to all my friends and family. Thanks again for your assistance Jerry!

Jerry was able to solve an issue even though the cars computer was telling him and other mechanics different things. Since my car is in good shape mechanically it's great to have the electrical issue solved. I highly recommend, even if it takes a few weeks he'll figure it out. Thanks Jerry

If you have vehicle electrical problems of any level of difficulty. Jerry is definitely an exceptionally person for the job. When Others couldn't 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. I'm truly grateful.

I've 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. I'm thrilled! Highly recommend you call about your tricky electrical mystery.

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.

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.

I went with my father to pick up his vehicle after getting it fixed. My family has been seeing Jerry for a while and never disappoints. He takes the time to thoroughly explain what's going on, what he found, and what he fixed. Honest man! We don't even live in West Chester, but we make the 35 minute drive just to see him!

I took my car to Keystone after I was having some issues caused by a poor stereo installer. Jerry at Keystone was able to diagnose the issue and found out that my car thought it was being stolen. He removed the poor wiring and watched the car over a few days to ensure that the problem didn't come back. The whole thing wasn't too expensive and they gave me a call a week later to check in and make sure that I wasn't experiencing any problems.

Jerry is honest, and have integrity. If you're having electrical issues in your car, don't take it to a mechanic or the dealership. Go to Jerry and Keystone.

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 don't find shops like this very often. Thank you again, Jerry!!

Usually I don't write reviews but these guys are just that awesome. It's 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!

My husband and I were moving and had trouble with the trailer we rented-- the electrical system in our car wouldn't hook up correctly, so the turn signals on the trailer weren't 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 didn't 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.
