Keystone Auto Services Customer Reviews

An impressive family operation! I was in need of a new auto mechanic. An acquaintance suggested Keystone auto repair. Their entire family has been going there for years. I was going on a road trip in 2 weeks and definitely needed my car worked on. Keystone auto repair is a family operation. They were very busy but squeezed me in any way. I am so impressed with them. They are truly honest, caring, friendly and take great pride in their work. I went in thinking I needed about $2500 of the work. Turns out half of the things did not need to be done as I was previously told.... Saved me about $1300. Keystone auto repair has a new happy thankful client forever!

I love this place to death and recommend them to anyone I can. They really know their stuff, and you don't have to worry about being taken advantage of: I don't know too much about cars, and they have told me multiple times that I don't need work done when I would have been happy to pay for it. I've been a customer for about 6 years, and they have always done quality work. Occasionally my mother has brought my car in and she's been impressed as well, and looking to use them when her new car is no longer under dealer warranty. Highly, highly recommend!!

They were extremely honest, competent and actually generous. I my car broke down and they diagnosed the issues, found out that there was a dealer recall on the part, and suggested I had the dealer fix it instead. Communication with Kim (and a mechanic there, we talked but I don’t know his name) was also great.

Had a coolant leak that I could not find. I never take my truck into the shop. Keystone diagnosed the leak and fixed it quick. They are very through and explain exactly what they did. I could not ask for anything more. This is a family run business, they so nice and professional. I would definitely go back.

I had quite the lengthy experience with Keystone Auto Service and unfortunately it left a pretty sour taste in my mouth. I've since moved away, so I won't be using them again, but writing a review to keep potential future customers aware. I took my Land Rover Discovery II to them for an overheating concern in December of 2021. Multiple mis-diagnoses later, it was determined that the vehicle was going to need some pretty serious engine work done to it. Since Keystone wasn't capable of doing the work and didn't have a machine shop that they knew of that could do it, the engine had to be taken to SoCal to be rebuilt. Even without this though, the timeline to fix the vehicle (over 7 months) is outrageous. Keystone did good work and eventually got the vehicle repaired and running properly again, but it wasn't without it's struggles. The owner tried to charge for mis-diagnosis multiple times, and I ended up paying way more for the repair than originally intended because of some of the mis-diagnosis that was done on the vehicle. I considered filing a complaint with BAR, but after discussions with friends determined that ultimately it wouldn't be worth it, so I am posting here. They did good work, but it took a really really long time and they tried to overcharge during multiple points during the process.

Referred by my wife who was referred by her brother! Genuine people. Family run business which is known by word of mouth. Had a water pump, thermostat & serpentine belt replaced. Also some other work I needed. I actually wanted hoses and pully's replaced but they assured me they were good for now! Saved me another $700, probably. Highly recommend!
