This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for your particular car key programmed.

The chip is contained inside the plastic portion of the key and there are a few different cuts that can be found on the keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.

The circuit in the induction coil will emit an electrical signal when the transponder is put into ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the computer inside the car detects the signal as valid it will turn off the vehicle immobilizer to allow the engine start.

If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.

When a car is connected with a specific fob it will only accept signals from that specific device. Other fobs won't work with the car, despite the fact that they look identical.
