The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.

The circuit in the induction coil will emit an electrical signal when the transponder is inserted into ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer in the car detects the signal as valid it will turn off the car immobilizer so that the engine can start.

If the car isn't able to recognize the transponder as the correct signal, it will not start the engine, and will warn you with flashing lights and a siren. This is designed to discourage people from trying to alter the vehicle, however it isn't a foolproof security measure. A determined and skilled thief could still evade this system by using a specific device that intercepts the signal.

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

There are several ways to program a key fob depending on the vehicle's model and make. You can sometimes do this yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.

When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle with which it is linked. The receiver then compares the data with the 'allowed signals' stored on the key fob and then opens or locks the car's door. If the information doesn't match, a chirping sound is heard and the car isn't able to function.

After the car has been paired with a specific fob, it only accepts signals from the device. In turn, other fobs will not work with the vehicle even though they have the same appearance. This is to safeguard the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.

The majority of car keys programmer dealers who are newer will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
