Transponder Chips

If your car was built in the past 20 years, then it has a transponder chip inside of it. This is a little plastic piece inside the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your car. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car.

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

A circuit inside the induction coil emits an electrical signal when the transponder is put into the ignition barrel. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.

If the car does not recognize the transponder signal as the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm. This is designed to discourage people from attempting to hack into the vehicle, but it's not a 100% security measure. A skilled and determined thief could still be able to get around this system employing a device designed to take over the signal.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start your vehicle from a distance, make chirping sounds to help locate the car, or switch on the heated steering wheel. Many of these extra features may appear convenient but they could make it difficult for you to keep the keys to your car.

Key fobs communicate with each other and the car using radio frequencies which are transmitted by a small antenna located in the center of the key. The transmission is encrypted, which helps to stop others from stealing and re-transmitting the signal.

Keyfobs can be programmed in a variety of ways depending on the model and make of your car. Certain models allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one.

When you press a key fob's button it transmits an encoded code to the car's receiver it is linked to. The receiver compared the information with the permitted signals stored on the key fob and then opens or locks the car's doors. If the information isn't in line an chirping sound is heard and the car isn't permitted to function.

Once the car key programming and cutting is linked with a particular fob, it will only accept signals from the device that is associated with it. In turn, other fobs will not work with the vehicle even if they look the same. This ensures the security of the computer system that runs the car and prevents unauthorised key fobs from taking control over it.

Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place that has the expertise to prepare the replacement fob is a dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by the consumer without the need for an authorized dealer.
