Transponder Keys

Transponder keys are often found in modern vehicles. They feature an RFID microchip that emits a unique car number when keys are inserted into ignition.

When the transponder key is inserted into the ignition, it sends an indication to the chip within the vehicle's engine control unit (ECU). The ECU will then check to see whether or not the number in the key matches its own digital serial number. If it does, the ECU is then able to disengage the immobilizer and permits the engine to start. If the code doesn't match then the ECU will reject it and prevent the engine from beginning.
