This is accomplished by making use of a special device that sends a code chip to unlock the doors or start the engine.

Some Lexus vehicles are designed with a key head that is a combination of the key head and remote. They are much easier to replace because there is no separate chip needed. This kind of key is also a bit less expensive.

Transponder Chips

Transponder chips are found in the key heads of a majority of new vehicles manufactured after 1995. They are used to disable immobiliser systems. If you've got a car key with a chip, the head is covered in a plastic cover that can be pulled off to reveal an L-shaped metal key. A replacement key or fob made with a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser system.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that contains a set of windings (very fine wire that is wrapped around a tube) which look similar to ones found in an electric motor. The windings create a coded signal that the car can read. If the code is correct the car will start.

There are two kinds of transponder chip, the first is called the 80-bit and the other is called the circle + (General Motors). The first type is reusable, but it must be removed using a special machine in order to work on a different vehicle compatible with it.

They can be salvaged, however and used with an ad-hoc key that doesn't require a battery in order to operate.

Immobiliser Systems

Immobiliser systems are electronic security devices that prevent thieves from starting your vehicle.

If the codes don't match, your engine will stop immediately and prevent theft of your vehicle.

Modern smart keys and fobs are equipped with embedded transponder chips that stores electronic security in a format that can't be duplicated. When the key or fob are inserted in the ignition, they transmit this code to the ECU. The ECU will then check it against the code that is stored in its memory and activates the fuel system and ignition circuit if they match. If the codes don't match then the engine will not start even if the ignition circuit is short-circuited by a thief.

The replacement of a key or fob involves a multi-stage procedure that includes cutting the new blade accurately and programming it so that it can be synced with the car's system.
