What our customers say on Google
I got my car from the auction without keys, David made a set for my car from scratch, and haven’t had any problems. Would recommend!
Fantastic experience and great pricing. The Toyota dealership would not deal with my door problems and sent me off, here I got my doors fixed and a key fob installed easily. Couldn't recommend more—very knowledgeable and friendly.
I've been using David with Carhax for a long time now and he's the best! He's done diagnosis as well as programming for me. He's truly a master of automotive electrical systems!
David was wonderful. He came to me when I was in a pinch working at a customer's home. He was timely, honest, & fixed the problem quickly. I would highly recommend his services.
Always dependable, always honest. Wouldn’t trust anyone else with my car.
David helped me get a car key programmed when my old one was lost. He is the best at what he does! I highly recommend him.
I had a key made for my Ford Fiesta by David and he was very quick to answer. He is very professional and upfront about all his costs and what exactly he is doing. He had a few options so I didn’t feel cornered into making a decision.
Fast and easy service, very friendly. Had 2 keys programmed for my Volvo, definitely recommend!
David is a very knowledgeable locksmith & programmer. Keyless entry on my truck was not working. He diagnosed the issue and got it working, then made several master keys for me. He communicated well and worked efficiently. Whether your car is a classic or a new model, I have confidence that David can help solve any dilemma.
I’ve had Carhax do more than 5 of my vehicles. (BMW, Mercedes, Toyota, Honda, Audi) The owner David is always quick to get out and does flawless work at a very fair price.
You know that warm fuzzy feeling you get when you find someone you can trust to work on your car? I have that feeling with David and Carhax. This is an honest and genuine person that really has your best interests in mind when making keys, etc.
Great service. Prompt and professional.
Fast to respond, great service!
David provides over-the-top service and is probably the most talented locksmith and auto mechanic in the state. Excellent pricing as well. Highly recommend him.
