The circuit in the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer on the car recognizes this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and warn you with flashing lights and an alarm.

When you press the button on a key fob the microchip sends a signal to the receiver inside the car with which it is paired. The receiver then compares this information to the signals that are allowed in the fob and then either locks or opens the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.

Once the car is paired with a specific fob, it can only receive signals from that device. In turn, other fobs won't work with the vehicle even if they appear similar. This protects the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
