Certain models require that the transponder chip contained in the key be programmed to function with the vehicle's immobiliser system. The Lexus models use different methods to program these chips.

Transponder Chips

Nearly all new cars built since 1995 have transponder chips embedded in the key head to disable the immobiliser system. The head of a key which is equipped with a transponder chip may be removed to reveal a metallic L-shaped key. A transponder chip replacement key or fob is a process that involves multiple stages. It involves cutting the keys accurately and programming the chip to communicate with the vehicle's immobiliser.

A transponder is an electronic chip with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire twisted around tubes) that resemble ones in an electric motor. These windings form a coded signal that the car can read. If the code is correct then the car will allow you to start it.

There are two kinds of transponder chips. One is known as the 80 bit, and the other one is called a circle + (General Motors). The former type is reusable but it needs to be unlocked by a specific machine in order to work in another compatible vehicle.
