Transponder Chips

The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the barrel of ignition. 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.
This stops the vehicle from being started by hot-wiring, or by tampering. The chip inside the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.

A circuit inside the induction coil will emit a signal when the transponder is put into an ignition barrel. programming car key is received by the chip which then transmits a signal to the vehicle. If the computer inside the car recognizes the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure.

These additional features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to connect with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal.
Keyfobs can be programmed in different ways based on the make and model of your car. Some cars allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a new key fob or additional one.
When you press the button on your key fob, the microchip inside transmits a code to the car's receiver it is linked to. The receiver then compares this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information does not match, the car will not be allowed to operate.
Once the car is associated with a particular fob, it can only receive signals from that device. Other fobs will not work with the car, even though they appear identical. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by the consumer without the need of an authorized dealer.
