The head of a key which has a transponder chip can be removed to reveal an L-shaped key. The process of getting a replacement key fob made with a transponder chip is a multi-stage procedure that includes precise cutting of the replacement keys and programming the transponder chip to link up with the vehicle's immobiliser system.

There are two types of transponder chips, one known as the 80 bit, and the other one is called a circle + (General Motors). The former type is reusable however it must be unlocked with a special device to work in another compatible vehicle.

Modern smart keys and fobs feature embedded transponder chips that stores electronic security in a format that can't be easily duplicated. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU examines the code against the one stored in its memory, and it activates both the fuel system as well as the ignition circuit if they match. If the codes do not match, the engine will not start even in the event that the ignition circuit is cut off by a criminal.
