When activated by an electro-magnetic field the chip emits a low level signal. The signal is then absorbed by the special antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your vehicle.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is received by the chip which sends a signal to the vehicle. If the car's computer recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.

There are a few different ways to program a key fob based on the model and make. It is possible to do this yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or additional fob.

When you press the button on a key fob the microchip sends signals to the receiver in the car with which it is paired. The receiver then compares the data with the permitted signals stored in 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 linked with a particular fob, it will only receive signals from that specific device. Other fobs will not work with the car, even though they look identical. This helps to protect the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place that has the experience to design the replacement fob is the service department of the dealer. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
