The head of a key which has a transponder chip can be removed to reveal a metal L-shaped key. A transponder-chip replacement key, also known as a fob is a multistage process.

There are two kinds of transponder chips, one known as the 80 bit and the other referred to as a circle + (General Motors). The first is reusable however it must be unlocked by a specific machine in order to be used in a compatible vehicle. The latter is more difficult since the earlier keys are usually damaged or drilled through, or discarded when key cases are replaced.

Modern smart keys and fobs contain an embedded transponder which stores electronic security information in a format that cannot be easily copied. When the fob or key are inserted in the ignition, they transmit this code to the ECU. The ECU is able to compare this code with the one that is stored in its memory, and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes do not match, the engine will not start - even if a burglar tries to short-circuit the ignition circuit.
