Transponder Chips

The majority of new lexus key cars manufactured after 1995 have transponder chips embedded in the key head to disarm the immobiliser system. The head of a key which contains a transponder chip is able to be removed to reveal a steel L-shaped key. The process of getting a replacement key fob that is made using transponder chips is a multi-stage procedure that includes precise cutting of the replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser.

A transponder is a device with Non-Volatile Memory. It has a set windings that are fine wires that are wrapped around a tube. They look like the ones in an electric motor. These windings produce a coded message that the car read. If the code is correct it will allow the car to start.

There are two kinds of transponder chip, one called the 80 bit and the other known as a circle + (General Motors). The former can be reused but must be delocked by a machine that is specially designed to function in a different compatible vehicle. The latter one is more difficult, as the older keys are often damaged and then drilled through or discarded after key cases are replaced. However they can be used with a service-key that doesn't require a battery.

Immobiliser Systems

An immobiliser is an electronic security feature that prevents thieves from starting your car. It operates by sending a signal from the car to the key when you attempt to start it. The chip inside the key responds by sending a unique number of codes that must match the one of the vehicle in order for it to start. If the codes aren't compatible, the engine will shut down immediately and stop the theft of your car.

Modern smart keys and fobs have an embedded transponder which stores electronic security information in a format that can't be copied easily. When your fob or key is placed in the ignition, it transmits this code to a receiver in the ECU. The ECU then compares it with the code that is stored in its memory and then activates the ignition system and fuel circuit if they coincide. If the codes don't match the engine won't start, even when the ignition circuit is short-circuited by a thief.

The process of replacing keys or fobs involves a multi-stage process that includes cutting the new blade with precision and programming it so that it works with your car's systems. Each immobiliser system is unique and has its own unique programming procedure.
