Professional Replacement for Modern Vehicle Keys

Car keys are no longer simple metal copies. Most modern vehicles use transponder chips, remote key fobs, or proximity smart keys that must be properly programmed to communicate with the vehicle’s immobilizer system.

We replace and program:

Transponder chip keys
Remote head keys
Key fobs
Push-to-start proximity keys
Emergency backup keys

Our process ensures your replacement key works properly with your vehicle — not just physically fits the lock.
