These chips are programmed using different methods depending on the model of Lexus. This is done by using a special device that sends an indication to the chip that is compatible with the code used to unlock the doors and start the engine.

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

Transponders are electronic device with Non-Volatile Memory (NVM) that has a set of windings (very fine wire that is wrapped around a tube) that resemble ones found 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 called the 80 bit and the other one is called a circle + (General Motors).
