A replacement key or fob that is made using a transponder chip is a multi-stage process that includes precise cutting of the replacement keys as well as programming the transponder chip to synch up with the vehicle's immobiliser system.

Transponders are electronic chip with Non-Volatile Memory (NVM) that houses a set of windings (very fine wire coiled around a tube) that look like the ones found in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct it will allow the car to start.

There are two types of transponder chips, one known as the 80 bit and the other is known as a circle + (General Motors). The former type is reusable however it must be unlocked by a special machine to function in a compatible vehicle. The second kind is more difficult to use because the old ones can be broken, drilled, or toss out when keycases are changed.

Immobiliser Systems

Immobiliser systems are electronic security measures which prevent thieves from starting up your vehicle.

If the codes aren't compatible, the engine will stop immediately, preventing theft of your car.

Modern smart keys and fobs come with an embedded transponder that stores electronic security information in a format which is not easily copied. When your fob or key is installed in the ignition it transmits this code to a device within the ECU. The ECU then compares it to the code stored in its memory and then activates the ignition and fuel system circuit if the two match. If the codes don't match the engine won't start even in the event that the ignition circuit is damaged by a thief.
