When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the car's computer recognizes this signal as the correct one, it will turn off the immobilizer on the vehicle and allow the engine to start.

The receiver compares the information with the 'allowed signals' that are stored on the key fob and then opens or locks the car's door. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even though they appear similar. This safeguards the integrity of the computer system in the car and blocks unauthorised key fobs from taking control of it.
