Transponder Chips

When activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is received by a specific 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 particular car.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer, allowing the engine to start.

When you press the button on a key fob the microchip transmits an indication to the receiver in the vehicle with which it is paired. The receiver compared this information with the signals that are allowed inside the fob, and either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car has been connected to a specific fob, it only accepts signals from the device. As a result, other fobs won't be able to work with the vehicle even if they have the same appearance.
