Transponder chips are likely be found in vehicles manufactured within the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car.

The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip inside the key is the right one for your particular car.

This prevents the vehicle from starting by hot-wiring or manipulating. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will be received by the chip and cause it to send a signal back to the car. If the car's computer recognizes this signal as being the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.

If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine, and will alert you with flashing lights and an alarm. This feature is designed to discourage people from trying to tamper with the vehicle, but it is not a foolproof security measure.

Key fobs communicate with each with the car via radio frequencies that are transmitted by an antenna in the center of the key. The communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.

There are a few different ways to program a key fob, based on your vehicle's make and model. You can sometimes do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.

When you press the button on a key fob, the microchip transmits an indication to the receiver in the car with which it is paired. The receiver then compares this information to the signals that are allowed inside the fob, and either locks or opens the door. If the information isn't in line an chirping sound is heard and the car isn't permitted to operate.

Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. This means that other fobs won't work with the vehicle even though they have the same appearance. This ensures the security of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that can only be found in the dealer service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems can be programmed with out the need for a dealership.
