Remotes

Lexus remotes and fobs aren't easy to replace and require locksmiths who are skilled and possess the appropriate tools. Certain models require the transponder on the key to be reprogrammed to allow it to communicate with the immobiliser of the vehicle. The lexus key shell models use different methods to program these chips. This is accomplished by using an electronic device that transmits an electrical signal to the chip which matches the code used to open the doors and start the engine.

Some lexus Car key cars are designed with a key head that is a combination of the key head and the remote. They are much easier to replace because there is no separate chip to replace. This kind of key could also be a little less expensive.

Transponder Chips

Transponder chips can be found in keys of nearly all new cars built since 1995. They are used to disarm immobiliser systems. The head of a key which contains a transponder chip is able to be removed to reveal an L-shaped key. A transponder-chip replacement key or fob is a multistage process. It involves cutting the keys accurately and programming the chip to communicate with the vehicle immobiliser.

A transponder is an electronic device with Non-Volatile Memory (NVM) that contains a set of windings (very fine wire twisted around tubes) that resemble ones in an electric motor. These windings generate a signal that the car can read. If the code is correct, then the car will allow you to start it up.

There are two kinds of transponder chip, the first is called the 80-bit and the second is known as the circle + (General Motors). The former can be reused however it must be unlocked with a special device to be used in a compatible vehicle. The second one is more difficult to use as the older keys could be damaged, drilled or toss out when keycases are changed. However they can be used with a key-service that does not require a battery.

Immobiliser Systems

Immobiliser systems are electronic security measures that deter thieves from starting up your car. It operates by sending a signal from your vehicle to the key whenever you attempt to start it. The electronic chip inside the key responds by sending a unique code that must match the one of the vehicle to allow it to start. If the codes don't match, the engine will immediately shut down to prevent theft.

Modern smart keys and fobs come with an embedded transponder which stores electronic security information in a format that cannot be easily copied. When the fob or key is inserted into the ignition, they transmit this code to the ECU. The ECU compares this code with the one it has stored in its memory and activates both the fuel system as well as the ignition circuit if they match. If the codes do not match, the engine won't be able to start - even if a burglar tries to short-circuit the ignition circuit.

The replacement of the fob or key involves a multi-stage procedure that includes cutting the new key blade accurately and programming it to ensure that it can be synced with your car's system. There are many different immobilisers used in different models and years and each one requires its own unique programming procedure.
