A circuit within the induction coil will emit signals when the transponder is put into ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer in the car detects the signal as being correct it will turn off the car immobilizer to allow the engine start. If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will warn you with flashing lights and a siren. automotive key programming is designed to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure.

If the data doesn't match an chirping sound is heard and the car isn't permitted to operate. After the car has been connected to a specific fob, it only accepts signals from that device.
