A transponder is a type of chip that has Non-Volatile Memory. It contains a set windings which are delicate wires that are twisted around a tube. They look like the ones in an electric motor. These windings produce a coded message that the car read. If the code is valid, then the car will allow you to start it up.

Immobiliser Systems

An immobiliser is an electronic security feature that deters thieves from starting your car. It operates by sending a signal from the car to the key when you attempt to start it. The chip inside your key responds with a unique code which must match the one in the vehicle in order to start. If the codes don't match, the engine will shut off immediately to stop theft.

Modern smart keys and fobs have an embedded transponder chip that stores electronic security in a format that cannot be duplicated. When your key or fob is inserted into the ignition, it transmits the code to a receiver within the ECU. The ECU examines the code against the one it has stored in its memory, and it activates the fuel system and the ignition circuit if they match. If the codes do not match, the engine won't be able to start - even if a burglar tries to short-circuit the ignition circuit.
