The chips are programmed with different methods depending on the model of Lexus. This is accomplished by using an electronic device that transmits a signal to the chip that is compatible with the code used to unlock the doors and start the engine.

Some Lexus cars are equipped with a single piece of hardware that consists of the key head and the remote. These are easier to replace since there is no separate chip. This kind of key may also be a bit less expensive.

It involves cutting the keys accurately and programming the chip to sync up with the vehicle's immobiliser.

A transponder is a chip that has Non-Volatile Memory. It has a set of windings that are fine wires wrapped around the tube. They look like the ones in an electric motor. These windings form a coded signal for the car to read. If the code is correct, then the car will allow you to start it up.

There are two types of transponder chips, the first is called the 80-bit and the second is called the circle + (General Motors). The former is reusable but must be delocked by a machine that is specially designed to function in a compatible vehicle. The latter is a bit more difficult, as the older keys are usually damaged or drilled through, or thrown away when key cases are replaced.

Immobiliser Systems

An immobiliser system is an electronic security measure which prevents thieves from opening your car. It works by sending a signal from your vehicle to your key when you attempt to start it.

If the codes do not match, your engine will immediately shut down to prevent theft.

Modern smart keys and fobs have an embedded transponder, which stores electronic security information in a format which is not easily copied. When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU compares this code with the one stored in its memory and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes don't match, your engine will not start - even if a burglar tries to short-circuit the ignition circuit.

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