Transponder Chips

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 barrel of ignition. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your car.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip in the car key ensures that the owner is the person who is the owner of the vehicle. This can reduce car theft.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer in the car recognizes the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine, and will warn you with flashing lights and siren. This feature is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A determined and skilled thief can still get around this system by using a specific device that intercepts the signal.

There are several ways to program a key fob, based on the model and make. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.
When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle that it is paired. The receiver then compares the data with the permitted signals stored in the key fob, and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car is linked with a specific fob it will only receive signals from that specific device. In turn, other fobs won't work with the vehicle, even though they look the same. This ensures the security of the computer system that runs the car and blocks unauthorized key fobs gaining control over it.
Most newer car dealerships will only accept cars with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer's service department. Certain aftermarket fobs, typically those for older models that have less advanced systems can be programmed with out the need for a dealer.
