Remotes

Replacing the Lexus remote or fob is an extremely complex process that requires skilled locksmiths who have the right tools and knowledge.

Transponder Chips

Transponder chips are found in the keys of nearly all new cars built since 1995. They can be used to disable immobiliser systems. If you've got a car key that has a chip inside it, the head comes with a cover that can be pulled off to reveal an L-shaped key. Making a replacement key, or 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 in order to synch up with the vehicle's immobiliser system.

A transponder is a device that has Non-Volatile Memory. It contains a set windings, which are fine wires wrapped around the tube. They resemble 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 up.

There are two types of transponder chip, one known as the 80 bit, and the other is known as a circle + (General Motors). The former type is reusable but must be delocked by a machine that is specially designed to function in a compatible vehicle. The latter is more difficult since the earlier keys are usually damaged and then drilled through or discarded after key cases are replaced. They can be salvaged, however and used with a service key that doesn't require a battery in order to function.

Immobiliser Systems

An immobiliser is a digital security device that prevents thieves from starting your vehicle. It works by sending a signal from your vehicle to the key whenever you attempt to start it. The chip inside the key responds by transmitting a unique code that must match the one of the vehicle to allow it to start. If the codes do not match, your engine will immediately shut down to stop theft.

Modern smart keys and fobs are equipped with an embedded transponder chip that stores electronic security in a format that cannot be duplicated. When the fob or key are placed in the ignition, they transmit this code to the ECU. The ECU is then able to compare it with the code that is stored in its memory, and activates the ignition and fuel system circuit if they match. If the codes do not match the engine won't start even in the event that the ignition circuit is short-circuited by a thief.

The process of replacing a key or fob involves an entire process that involves cutting the new blade precisely and programming it to ensure that it can be synced with the car key lexus's system. Each immobiliser system is distinct and has its own programming procedure. We utilize Ross-Tech to ensure that the replacement key is correctly programmed.
