Certain models require that the transponder chip in the key be changed in order to work with the car's immobiliser system. The chips are programmed with different methods, based on the model of duplicate lexus key. This is done using a specific device that sends a signal to the chip that matches the code used to open the doors and 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, as there is no separate chip required. This kind of key may also be a little cheaper.

The head of a key that has a transponder chip can be removed to reveal an L-shaped key. A transponder-chip replacement keys or fob is a multi-stage procedure. It involves cutting keys precisely and programming the chip to communicate with the vehicle's immobiliser.

A transponder is a chip that has Non-Volatile Memory. It is comprised of a set of windings, which are very fine wires that are wrapped around the tube. They look similar to those in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct the car will start.

There are two kinds of transponder chips, one called the 80 bit and the other one is called a circle + (General Motors). The first kind is reusable, however it needs to be unlocked using a special machine in order to work in a different vehicle that is compatible. The second kind is more difficult to use due to the fact that the old ones can be broken, drilled or removed when key cases are changed. They can be salvaged, however, to use with a service key that doesn't require batteries to operate.

Immobiliser Systems

An immobiliser system is an electronic security measure that deters thieves from starting your car. It operates by sending an electronic signal from your car to the key whenever you try to start it. The chip inside the key responds with an unique code that must match the one in the vehicle in order to start. If the codes do not coincide, your engine will immediately shut down to prevent theft.

Modern smart keys and fobs have an embedded transponder chip that stores security information in a format that can't be duplicated. When the key or fob are inserted into the ignition, they send this code to the ECU. The ECU examines the code against the one that is stored in its memory and activates the fuel system and the ignition circuit if they match. If the codes don't match, the engine won't start - even if a burglar tries to short-circuit the ignition circuit.

The process of replacing the fob or key requires an entire process that involves cutting the new blade with precision and programming it so that it can be synced with the car's system. There are many different immobiliser systems used in different models and years and each one requires its own distinct programming process.
