Transponder Keys

Transponder keys are typically used in newer cars. They have an RFID microchip that sends a unique code for the car when the key is inserted into ignition. The idea behind this technology is to prevent theft by making sure that only the right key can start the vehicle. If you'd like to know more about the technology's working get in touch with your local locksmith or dealership for demonstrations.

When the transponder is placed into the ignition, the key transmits an electronic message to the chip that is inside the engine control unit (ECU) of the vehicle. The ECU examines if the number on the key matches the digital serial number of the ECU. If it does then the ECU removes the immobilizer, allowing the engine to start. If the code doesn't match, the ECU will reject it and stop the engine from beginning.

These keys are more expensive than traditional metal keys but give you extra security. However, car thieves have adapted over time and have found ways to circumvent this anti-theft device and so the additional cost is not enough to deter them entirely.
