If you've got a key with a chip inside, the head is covered with a plastic cover which can be pulled off to reveal an L-shaped key. A transponder-chip replacement key, also known as a fob is a multi-stage process. It involves cutting the keys with precision and programming the chip to sync up with the vehicle's immobiliser.

Transponders are chips that has Non-Volatile Memory. It has a set of windings that are fine wires that are wrapped around a tube. They look like the ones in an electric motor. The windings generate a coded message that the car read. If the code is correct it will allow the car to start.

If the codes do not match, the engine will stop immediately to stop theft.

Modern smart keys and fobs contain an embedded transponder that can store electronic security information in a format which is not easily copied. When the key or fob is inserted into the ignition, they transmit this code to the ECU. The ECU then compares it to the code in its memory. It then activates the ignition and fuel system circuit if they match. If the codes don't match, the engine will not start even in the event that the ignition circuit is cut off by a criminal.
