Transponder Keys

Transponder chips will likely be installed in cars that were built in the last 20 years. These microchips are located in the handle of the key and transmit a signal to the onboard computers in your vehicle when you use the key. The computer onboard examines the digital serial number of the chip before allowing the car to begin. This helps prevent theft of cars, as thieves would need to know your unique serial number to be able to steal it.

The microchip in your car key transmits a low-level radio signal to the receiver inside the car. This radio signal activates the microchip, which transmits a code to the onboard computer of the car. The car will recognize this code and only allow it to start when the key is the right one. This prevents "hot wiring" or other methods of stealing cars.
