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 a tiny piece of plastic on the back of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.

When activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is fitted around the ignition barrel of your car. This allows the vehicle's computer system to confirm that the transponder chip in the key is the correct one for your particular car.

This prevents the vehicle from being started through either hot-wiring or by manipulating. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.

A circuit inside the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car keys programming is able to recognize the signal as being correct, it will disable vehicle immobilizer to allow the engine start.

If the car does not recognize the transponder signal as being the right one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A skilled and committed thief might be able escape this security system by using a device that can detect the signal.

A lot of these features may appear convenient but they could make it harder for you to keep the track of your car keys.

Key fobs are able to communicate with each with the car key reprogrammed via radio frequencies that are transmitted through a small antenna located in the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.

There are many ways to program a key fob depending on your vehicle's model and make. You can sometimes do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or a second fob.

When you press the button on a key fob the microchip sends a signal to the receiver inside the car with which it is linked. The receiver compares this information with the signals that are allowed inside the fob, and either locks or opens the door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to function.

After the car has been associated with a particular fob, it only accepts signals from that device. Other fobs won't work with the car, despite the fact that they appear similar. This helps to protect the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

Most dealerships with newer cars will only work with cars with original fobs or genuine replacements supplied by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for dealers.
