Can you program a key fob on-site?+
Yes. We program transponder keys, proximity/smart keys and push-to-start fobs directly at your vehicle in Southlake, Colleyville, Keller, Grapevine, Westlake and Trophy Club. Typical on-site time: 30–60 minutes.
How much does key fob programming cost in Southlake?+
Programming a dealer-purchased fob to your car runs $75–$185 on-site. Supply + programming of a new transponder or smart key ranges $180–$650 depending on vehicle. Luxury brands $400–$1,100. Exact price confirmed before dispatch.
My key fob stopped working — does it need programming or just a battery?+
Call us before replacing. Most dead fob issues are resolved with a CR2032/CR2025 battery swap (under $10). If the fob still won't pair after a battery change, it may need reprogramming — we diagnose on the phone for free.

All major makes from 2001–2026. BMW, Mercedes, Lexus, Audi, Porsche, Range Rover, Tesla, Toyota, Honda, Ford, Chevrolet, Nissan, Infiniti, Acura, Jaguar, Cadillac, RAM, Jeep, Chrysler, and more.
Do you program all-keys-lost smart keys?+
Yes — even when all working keys are lost. Our technicians extract the vehicle's security code (PIN/SKIM/ISN) on-site and pair a fresh smart key, no dealer needed.
