The head of a key which is equipped with a transponder chip may be removed to reveal a metallic L-shaped key. Having a replacement key or fob made of a transponder chip is a multi-stage method that involves precise cutting of replacement keys and programming of the transponder chip in order to synch up with the vehicle's immobiliser system.

A transponder is a chip that has Non-Volatile Memory. It has a set of windings, which are fine wires wrapped around the tube. They look like those in an electric motor. These windings produce a coded message that the car read. If the code is correct it will allow the car to start.

There are two types of transponder chip, one called the 80 bit and the other referred to as a circle + (General Motors).

When the fob or key is inserted into the ignition, they transmit this code to the ECU. The ECU then compares it with the code that is stored in its memory and then activates the fuel system and ignition circuit if they coincide. If the codes don't match, the engine will not start, even when the ignition circuit is damaged by a thief.
