Keys

Take the battery out (using the paperclip) and then insert the new one making sure that it's pointing the right way up. Clip the inside of the metal key back together.

Remotes

Replacing the Lexus remote or fob is a complicated process and requires expert locksmiths with both the right tools and experience. Certain models require that the transponder chip within the key be reprogrammed to function with the immobiliser system of the car. The lexus key cutting models employ different methods to program these chips. This is accomplished by using a special device that sends a signal to the chip that matches the code used to open the doors and start the engine.

Some Lexus cars are equipped with a single piece of hardware that consists of the key head as well as the remote. They are much easier to replace because no separate chip is required. This kind of key may also be a bit less expensive.

Transponder Chips

Transponder chips are in the keys of nearly all new vehicles manufactured after 1995. They are used to disable immobiliser systems. If you've got a key with a chip inside, the head comes with a cover which can be pulled off to reveal an L-shaped metal key. The process of getting a replacement key fob with transponder chips is a multi-stage process that includes accurate cutting of the replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser.

A transponder is an electronic device with Non-Volatile Memory (NVM) which contains a set of windings (very fine wire twisted around the tube) that resemble ones found in an electric motor. These windings produce a coded message 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 first is reusable however it must be unlocked by a specific machine in order to function in a compatible vehicle. The second is more difficult to use due to the fact that the older keys could be broken, drilled or removed when key cases are changed. However they can be utilized with a service key that does not require batteries.

Immobiliser Systems

An immobiliser is an electronic security measure that deters thieves from starting your car. It operates by sending a signal from your vehicle to the key when you attempt to start it. The electronic chip inside your key responds by sending an individual code that must match the one found in the vehicle in order to start. If the codes don't match, the engine will shut off immediately to prevent theft.

Modern smart keys and fobs are equipped with an embedded transponder that stores electronic security information in a format that cannot be easily copied. When the fob or key are inserted in the ignition, they transmit this code to the ECU. The ECU analyzes this code in comparison to the one in its memory, and it activates both the fuel system as well as the ignition circuit if they match. If the codes do not match then the engine will not start even in the event that the ignition circuit is short-circuited by a burglar.
