When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the car's computer system to verify that the transponder chip inside the key is the correct one for the car you have.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will then get received by the chip and cause it to send a signal back to the car. If the car's computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to 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 people from tampering with the vehicle. However, it is not a foolproof measure of security.

You can program a keyfob in different ways based on the model and make of your vehicle. You may be able to do it yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When you press a key fob's button the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver compared this information with the signals that are allowed inside the fob, and either opens or closes the door. If the information does not match, the car will not be allowed to drive.
Once the car is paired with a particular fob, it will only receive signals from that device. Other fobs won't work with the car, even though they appear identical. This ensures the security of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer.
