Transponder Chips

Transponder chips can be found in cars manufactured in the last 20 years. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your vehicle.

The circuit in the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as the correct one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and committed thief may still be able to bypass this system by employing a device designed to intercept the signal.

Key fobs communicate with each with the car via radio frequencies which are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.

Keyfobs can be programmed in a variety of ways depending on the model and make of your car. Some cars allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order 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 in the car with which it is linked. The receiver compares this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information does not match the signals, the car will not be allowed to run.

After the car key programing has been connected to a specific fob, it can only receive signals from the device. Other fobs won't work with the car, even if they appear identical. This safeguards the integrity of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills which can only be obtained in the dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by consumers without the need of a dealership.
