A working spare key — chip and remote fully programmed, tested on your car before you leave.
A copy that turns in the ignition but the car won't start because the transponder chip was never actually programmed. A remote that locks but won't unlock. Being told mid-appointment that your situation needs "all keys lost" service that isn't offered here. Key copying looks simple, but chip programming is where cheap or rushed copies fail. Pro Car programs and tests every function — ignition, lock, unlock, panic — on your actual car before you pay.
We take your existing key, cut a physical blank to match, program the transponder chip so the car recognizes it, program the remote functions, and test everything on your car before you leave.
Every function checked on your car, not assumed.
Not just a cut blank that turns but won't start the car.
We copy existing keys only; we're clear about that before you book, not after.
