Transponder Chips

If your car is made within the past 20 years, it is likely that it has a transponder inside of it. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.

The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna attached to the ignition barrel. This allows the car's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.

This stops the vehicle from being started by hot-wiring or tampering. The chip inside the key also confirms that you are the legal owner of the vehicle. This can help to reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will then get received by the chip, causing it to transmit a signal to the car. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This is designed to discourage people from trying to hack into the vehicle, but it is not a foolproof security measure.

When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is linked. The receiver compared the information with the permitted signals stored in the key fob, and then opens or locks the car door. If the data does not match the fob's information, the car won't be allowed to drive.

Once the car has been connected to a specific fob, it can only receive signals from that device. Other fobs won't work with the car key programmed, even though they look like. This helps to protect the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.

Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security expertise that is only available in the dealer's service department.
