Certain models require the transponder inside the key to be changed to work with the immobiliser of the vehicle. The lexus ignition key replacement models employ different methods to program these chips. This is done using a special device which sends a code to the chip to unlock the doors or to start the engine.

Certain Lexus automobiles are built with a single piece of hardware that includes the key head and remote, and these are easier to replace since there is no separate chip. This type of key can also be a little less expensive.

Transponder Chips

Nearly all new cars since 1995 have transponder chips within the key head to disable the immobiliser system. The head of a key which contains a transponder chip is able to be removed to reveal a metallic L-shaped key. Making a replacement key, or fob that is made using transponder chips is a multi-stage procedure that includes accurate cutting of the replacement keys and programming of the transponder chip to link up with the vehicle's immobiliser system.

A transponder is a device with Non-Volatile Memory. It has a set windings, which are fine wires that are 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.

There are two kinds of transponder chips. One is known as the 80 bit, and the other referred to as a circle + (General Motors). The first is reusable, but it must be delocked using a specific machine to function on a different vehicle compatible with it. The second one is more difficult to use due to the fact that the old ones can be damaged, broken or toss out when keycases are changed. However, they can be used with a service-key that doesn't require a battery.

Immobiliser Systems

An immobiliser is a security measure that uses electronic technology that prevents thieves from starting your car. It works by sending an electronic signal from the car to the key each time you attempt to start it. The chip inside your key responds with a unique code that must match that in the vehicle in order to start. If the codes don't coincide, your engine will stop immediately to stop theft.

Modern smart keys and fobs feature an embedded transponder chip that stores electronic security in a format that cannot be easily duplicated. When your key or fob is installed in the ignition it transmits this code to a receiver within the ECU. The ECU is able to compare this code with the one in its memory, and then activates both the fuel system and the ignition circuit if they match. If the codes don't match the engine won't start even when the ignition circuit is damaged by a thief.

The procedure of replacing a key or fob involves an entire process that involves cutting the new blade with precision and programming it so that it works with your car's system. Every immobiliser system is unique and has its own programming procedure. We utilize Ross-Tech to ensure that the replacement key is correctly programmed.
