Transponder Chips

If your car is made within the past 20 years, then it has a transponder inside of it. This is the little piece of plastic 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 a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for your specific vehicle.

A circuit within the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer on the car recognizes this signal as being the correct one, it will disable the vehicle's immobilizer and allow the engine to begin.

If the vehicle does not recognize the transponder signal as the right one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A determined and skilled thief can still get around this system by using a specific device that intercepts the signal.

You can see that a transponder is a great option. Every car owner should take this into consideration in order to safeguard their investment and minimize theft risk.

There are a few different ways to program a key fob, based on your vehicle's model and make. It is possible to do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.

When you press a key fob's button, the microchip inside transmits an encoded code to the car's receiver that it is paired with. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car's door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.

Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even though they look similar. This protects the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control of the vehicle.

The majority of newer dealers will only work on a car with original fobs or genuine replacements 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 service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need for dealers.
