Transponder Chips

Transponder chips are likely to be found in cars manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by the antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your vehicle.

This is the reason why hot-wiring or tampering with the ignition system of your vehicle to start it. The chip inside the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer onboard the car detects the signal as being correct, it will disable vehicle immobilizer so that the engine can start.

If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and notify you via flashing lights and a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief can still get around this system by using a specific device that intercepts the signal.

Key fobs communicate with one other and the car using radio frequencies that are transmitted through an antenna that is located in the center of the key. The communication is encrypted, which helps keep others from stealing and retransmitting the signal.

You can program a keyfob in different ways based on the model and make of your car. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob or additional one.

When you press the button on a key fob the microchip sends a signal 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 locks or opens the car door. If the information doesn't match, a chirping sound is heard and the car isn't able to function.

Once the car is associated with a particular fob, it only accepts signals from that device. Other fobs won't work with the programing car keys, even if they appear identical. This safeguards the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control of it.

Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the knowledge to create a replacement fob is in a dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems can be programmed by consumers without the need of dealers.
