Transponder Chips

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the barrel of ignition. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This stops the vehicle from being started by hot-wiring or manipulating. The chip inside the car key verifies that the owner is the person who owns the vehicle. This can help to reduce car theft.
Transponder keys resemble regular keys made of metal, but with a plastic cap. The chip is housed inside the plastic portion of the key and there are different types of cuts on these keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car is able to recognize the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and a siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief could still bypass this system by using a specific device that detects the signal.

Key fobs communicate with one with the car via radio frequencies which are transmitted through a small antenna located in the middle of the key. This signal is encrypted to prevent others from stealing or stealing the signal.
There are a few different ways to program a key fob based on the vehicle's model and make. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or additional one.
When you press a key fob's button it transmits a code to the car's receiver that it is linked to. The receiver then compares this information with the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information does not match the fob's information, the car won't be allowed to drive.
After the car has been connected to a specific fob, it only accepts signals from the device. As a result, 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 also to stop the use of unauthorized key fobs to gain control of the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements sold by the manufacturer. It is because the only place with the experience to design the replacement fob is a dealer's service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed without the need for a dealership.
