Some models require the transponder within the key to be reprogrammed so that it can work with the immobiliser system in the car. These chips are programmed by different methods based on the model of lexus spare key. This is done using an electronic device that transmits an electronic signal to the chip that is compatible with the code used to open the doors and start the engine.

Transponder Chips
Transponder chips are in the key heads of a majority of new vehicles manufactured after 1995. They can be used to disable immobiliser systems. If you’ve got a key with a chip in it the head is covered with a plastic cover which can be pulled off to reveal an L-shaped metal key. A transponder-chip replacement keys or fob is a multistage process. It involves cutting the keys accurately and programming the chip to make it sync 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 fine wires coiled around the tube. They look like the ones in an electric motor. These windings generate a 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 chip. The one is known as the 80-bit and the second is known as the circle + (General Motors). The former type is reusable but must be delocked with a special device to be used in a compatible vehicle. The latter is a bit more difficult as the old keys are often damaged, drilled through or discarded when key cases are replaced.

If the codes do not match, your engine will immediately shut down to stop theft.
Modern smart keys and fobs have embedded transponder chips that stores security information in a format that can’t be duplicated. When your key or fob is put into the ignition, it transmits the code to a receiver inside the ECU. The ECU is then able to compare it with the code stored in its memory. It then activates the fuel system and ignition circuit if they coincide. If the codes do not match the engine won’t start, even when the ignition circuit is cut off by a criminal.
The process of replacing keys or fobs involves a multi-stage process that includes cutting the new blade precisely and programming it to ensure that it works with your car’s security system.
