We program keys for Toyota, Honda, Ford, Chevrolet, Nissan, BMW, Mercedes, Hyundai, Kia, and many more.

Frequently Asked Questions
What is a transponder key?
A transponder key contains a small electronic chip that communicates with your vehicle's immobilizer system. If the chip isn't programmed correctly, the car won't start even if the key turns in the ignition.
Can you program a key I bought online?
In many cases, yes. However, aftermarket keys vary in quality and compatibility. We recommend calling us first to confirm compatibility before purchasing a key online.
How long does key programming take?
Most key programming jobs take between 20 and 45 minutes depending on the vehicle make, model, and key type.
Do I need to be present during programming?
Yes. You need to be present with proof of ownership and a valid photo ID. The vehicle must also be present and accessible.
Can you program keys for all car brands?
We program keys for most major domestic and foreign brands. Call us with your vehicle's year, make, and model to confirm we can service your car.
