Transponder Chips

When it is activated by an electro-magnetic field the chip emits a low-level signal. This 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 transponder chip of the key is the correct one for your car.
This is what stops hot-wiring or tampering with the ignition system of your vehicle to get it started. The chip in the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.

A circuit within the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the car's computer detects this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined thief may still be able to get around this system employing a device designed to detect the signal.

Key fobs make use of radio frequencies to communicate with each other and the car. These frequencies are transmitted through a small antenna located within the middle of the key. This communication is encrypted, which helps keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your car. Certain models allow you to do this yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.
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. key programming near me compares this information with the signals that are allowed in the fob and then either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to function.
When a car is connected with a specific fob, it will only receive signals from that device. This means that other fobs will not work with the vehicle even if they look the same. This helps to protect the integrity of the car's computer system and prevent unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only deal with cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the only place that has the knowledge to create the replacement fob is the service department of a dealer. Some aftermarket fobs, usually those from older models that have less advanced systems can be programmed without the need for a dealer.
