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

A circuit inside the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and alert you with flashing lights and an alarm. This is designed to deter people from trying to hack into the vehicle, but it's not a 100% security measure.

When you press the button on a key fob, the microchip sends an indication to the receiver inside the vehicle that it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob, and then it opens or closes the Car key reprogram's doors. If the data doesn't match an chirping sound is heard and the car isn't able to operate.

When a car is connected with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even if they appear similar. This safeguards the integrity of the computer system in the car and blocks unauthorised key fobs from taking control of it.
