Transponder chips are found in the key heads of a majority of new vehicles manufactured after 1995. They are used to disarm immobiliser systems. If you've got keys with a chip, the head comes with a cover that can be pulled off to reveal an L-shaped metal key. A transponder chip replacement key or fob is a multistage process. It involves cutting the keys precisely and programming the chip to make it sync with the vehicle's immobiliser.


Transponders are chips with Non-Volatile Memory. It has a set of windings, which are delicate wires that are twisted around a tube. They resemble the ones in an electric motor. The windings are coded to create a signal for the car to read. If the code is valid, then the car will allow you to start it up.
