Transponder Key Replacement / Transponder Key Programming

Modern vehicle keys feature transponder chips that form a security link with your car. This technology ensures only properly programmed keys can start your engine through encrypted communication.

The car security system provides protection through verification, which is automated when the key is inserted into the ignition:

  1. The key transmits its unique coded signal
  2. The vehicle's security system validates the code
  3. Engine start is authorized after verification
