What is a Car Transponder Key?

A car transponder key is a special key that contains a small electronic chip. This chip sends a signal to your car's transceiver. The car will start if the signal matches the one stored in your computer. If the signals don't match, the car won't start. Transponder keys are also known as chip keys because of their small chip.

Key points:

  • Car transponder keys enhance vehicle security.
