Transponder Chips

If your car is made in the last 20 years, then it has a transponder chip 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 that has a unique code to the vehicle you own.

When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then absorbed by a special antenna attached to the ignition barrel. This allows the vehicle's computer system to verify that the transponder chip inside the key is the right one for the car you have.

This stops the vehicle from being started by either hot-wiring or by tampering. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This can reduce car theft.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the computer inside the car recognizes the signal as correct, it will disable vehicle immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and warn you with flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an absolute security measure.

Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are sent by a small antenna inside the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.

There are several ways to program a key fob based on the vehicle's model and make. Certain models allow you to do this yourself. However, most newer models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one.

When you press the button on a key fob the microchip sends an indication to the receiver inside the car that it is paired. The receiver compares the information with the permitted signals stored on the key fob and then it opens or closes the car's doors. If the information isn't in line an chirping sound is heard and the car isn't able to operate.

Once the car is associated with a particular fob, it will only accept signals from the device. As a result, other fobs won't be able to work with the vehicle, even though they appear similar. This is to safeguard the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.

Most newer car dealerships will only work with 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 an appropriate replacement fob is the service department of a dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
