Transponder Chips

When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then absorbed by the special antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your car.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This can reduce car theft.

A circuit within the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal will be received by the chip and cause it to send a signal back to the car. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and an alarm. This system is designed to deter individuals from tampering with the vehicle. However it's not a foolproof measure of security.

These extra features can make it difficult for you to locate your car keys.
Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are sent by a small antenna within the middle of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.
There are a few different ways to program a key fob based on the vehicle's make and model. It is possible to do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob the microchip transmits signals to the receiver inside the car with which it is paired. The receiver then compares this information to the 'allowed' signals in the fob and then either opens or locks the door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is associated with a particular fob, it can only receive signals from that device. This means that other fobs won't work with the vehicle, even though they appear similar. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control over the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are offered 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. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by the consumer without the need of a dealership.
