lexus ignition key replacement remotes and fobs aren't easy to replace and require locksmiths who are knowledgeable and have the right tools. Certain models require the transponder inside the key to be programmed in order to function with the immobiliser system in the car. These chips are programmed using different methods, based on the model of 2006 Lexus Rx400H Key Fob (Https://Olderworkers.Com.Au). This is done by using an electronic device that transmits a signal to the chip that matches the code used to unlock the doors and start the engine.

Transponder Chips

If you have a key with a chip inside, the head comes with a cover that is able to be pulled off to reveal an L-shaped key. A transponder-chip replacement key or fob is a multistage process. It involves cutting the keys precisely and programming the chip to sync up with the vehicle's immobiliser.

Transponders are electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire that is wrapped around the tube) which look similar to ones found in an electric motor. These windings form a coded signal for the car to read. If the code is correct it will allow the car to start.

There are two kinds of transponder chips. One is known as the 80 bit, and the other known as a circle + (General Motors). The former type is reusable however it must be unlocked by a machine that is specially designed to work in another compatible vehicle. The second one is more difficult to use due to the fact that the old keys can be damaged, broken or removed when key cases are changed.

If the codes don't match, the engine will shut off immediately to stop theft.

Modern smart keys and fobs have an embedded transponder that stores electronic security information in a format that is not easily copied. When the key or fob are inserted in the ignition, they send this code to the ECU. The ECU then compares it with the code stored in its memory. It then activates the ignition and fuel system circuit if the two coincide. If the codes do not match then the engine will not start, even if the ignition circuit is short-circuited by a thief.
