The head of a key which is equipped with a transponder chip may be removed to reveal an L-shaped key. A replacement key or fob with a transponder chip is a multi-stage process which includes precise cutting of replacement keys and programming the transponder chip to synch up with the vehicle's immobiliser system.

A transponder is an electronic chip that has Non-Volatile Memory (NVM) that has a set of windings (very fine wire that is wrapped around tubes) that resemble ones found in an electric motor. These windings produce a coded message that the car will read. If the code is correct then the car will allow you to start it.

There are two types of transponder chip, the first is called the 80-bit while the other is called the circle + (General Motors). The first is reusable, but must be unlocked with a special machine in order to work in a different vehicle that is compatible. The latter is more difficult, as the older keys are often damaged and drilled or thrown away when key cases are replaced. However, they can be used with a key-service that does not require batteries.

Immobiliser Systems

Immobiliser systems are electronic security measures which prevent thieves from starting your car. It works by sending an electronic signal from the vehicle to the key every time you try to start it. The chip inside the key responds with a unique code which must match that in the vehicle in order to start. If the codes don't match, your engine will stop immediately, preventing theft of your car.

Modern smart keys and fobs have an embedded transponder which stores electronic security information in a format that can't be copied easily. When your key or fob is put into the ignition, it transmits the code to a receiver within the ECU. The ECU then compares it with the code stored in its memory, and activates the ignition and fuel system circuit if they match. If the codes don't match and the engine does not start even when the ignition circuit is short-circuited by a thief.

The replacement of keys or fobs involves an entire process that involves cutting the new key blade accurately and programming it to ensure that it works with your car's system. Each immobiliser is unique and has its own unique programming procedure. We employ Ross-Tech to ensure that the replacement key is correctly programmed.
