Transponder Chips

When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.

If the computer on the car recognizes this signal as being the right one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.

When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, despite the fact that they appear identical.
