Keys

Lexus keys are not easy to replace and require a specialist car key replacement locksmith to make a working spare. This is because every Lexus key contains microchips that need to be programmed to work in conjunction with the immobiliser of your vehicle If it is not, the car will not be able to start.

This can be done yourself but you'll need a small Phillips Screwdriver, 20p coin and paperclip. On the back of the fob you will see either one or two screws take them off and place them in a secure place (they're small and easy to lose). Remove the fob and you will see an indentation that is circular for the key made of metal. Pop the battery out (using the paperclip) and then insert the new one, making sure it is the right way up. Then clip the inside of the key back to the fob.

Remotes

Replacing a Lexus remote or fob is difficult and requires expert locksmiths with both the right tools and knowledge. Certain models require the transponder on the key to be changed to work with the immobiliser system of the car. The Lexus models use different methods to program these chips. This is accomplished by making use of a special device that sends a code chip to unlock the doors or to start the engine.

Certain Lexus vehicles are designed with a unit that combines the key head and remote. They are easy to replace, since there is no separate chip needed. This kind of key could also be a bit less expensive.

Insert the coin (20p is a good choice) into the hole and twist. You will see an area flat that you can get rid of using a paperclip.

Then, take out the old battery and replace it with the new one. Make sure that the replacement battery is installed with the proper direction of operation. Clip the two sides of the fob together, then insert the key in the metal.


Transponder Chips

Most new cars since 1995 have transponder chips in the key head that allow it to deactivate the immobiliser system. If you've got a key with a chip in it the head is covered with a plastic cover that is able to be pulled off to reveal an L-shaped key. Having a replacement key or fob that is made using transponder chips is a multi-stage process which includes accurate cutting of the key replacements and programming the transponder chip in order to synch up with the vehicle's immobiliser.

There are two types 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 but must be delocked with a special device to be used in a compatible vehicle. The second is more difficult to use as the old keys can be broken, drilled, or toss out when keycases are changed.

Immobiliser Systems

Immobiliser systems are electronic security measures that stop thieves from starting up your vehicle. It works by sending an electronic signal from your car to the key every time you attempt to start it. The chip inside the key responds by sending a unique code which must match that of the vehicle in order for it to start. If the codes aren't compatible, the engine will shut down immediately and prevent theft of your vehicle.

Modern smart keys and fobs come with an embedded transponder chip that stores security information in a format that cannot be easily duplicated. When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU is able to compare this code with the one stored in its memory and activates both the fuel system as well as the ignition circuit if they are compatible. If the codes do not match and the engine does not start even when the ignition circuit has been short-circuited by a thief.

Every immobiliser system is unique and has its own programming procedure.
