The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your vehicle.

A circuit within the induction coil emits a signal when the transponder is placed in the the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start.

The receiver 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 fob's information, the car won't be allowed to drive.
When a car is connected with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, despite the fact that they look similar.
