Keys
Lexus keys are not easy to replace and require a professional locksmith for car keys to make a working spare. This is because each Lexus key is equipped with an electronic chip that needs to be programmed to sync with the immobiliser of your vehicle and if it's not, it'll not be able to start.
The process takes time and special equipment to execute properly, and each model has a distinct programming procedure. Replacing a lost or damaged key or fob is a costly job and one you should leave to professionals unless your have the right tools and know-how.
You will need to replace the batteries in your smart or conventional key. Both keys function by turning the barrel of the ignition. This can be done yourself however, you'll require an inexpensive Phillips Screwdriver, 20p coin and paperclip. On the back of the fob, you will see two or one screw loosen them and place them somewhere safe (they're small and easy to lose).

Insert the new battery, making sure that it is inserted correctly. Clip the inside of the key back together.
The Keylab remotes and fobs can be difficult to replace and require locksmiths who are knowledgeable and have the right tools. Certain models require that the transponder chip in the key be reprogrammed to function 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 transmits a code to the chip to unlock the doors or start the engine.
Certain Lexus cars are designed with a single unit that includes the key head and remote. These are easier to replace since there is no separate chip. This kind of key may also be a bit less expensive.
All fobs eventually lose battery power, regardless of the type of key. This is a stressful experience, but it's possible to get your Lexus back to normal with a little know-how. First, consult the owner's manual to determine what kind of battery you require and locate an alternative. Find a small hole on the inside of the fob. Insert an amount of money (20p is a good choice) into the hole and then twist. There should be an area flat that you can remove with a paperclip.
Then, take out the old battery and replace it with the new one. Make sure the new battery is in the proper direction of operation. Finally, cut the inside of the fob back together, and reconnect the key to the metal.
Transponder Chips
Most new cars built since 1995 have transponder chips embedded in the key head to disable the immobiliser system. If you've got a car key with a chip, the head is covered with a plastic cover that can be pulled off to reveal an L-shaped key. A transponder chip replacement key or fob is a process that involves multiple stages. It involves cutting the keys with precision and programming the chip to connect with the vehicle immobiliser.
A transponder is a type of chip that has Non-Volatile Memory. It has a set windings, which are very fine wires that are wrapped around a tube. They look like those in an electric motor. These windings transmit a message that the car is able to read. If the code is correct, then the car will allow you to start it.
There are two types of transponder chips. The one is known as the 80-bit and the second is called the circle + (General Motors). The first is reusable, however it needs to be unlocked using a special machine in order to work on a different vehicle compatible with it. The latter is more difficult as the old keys are usually damaged, drilled through or discarded after key cases are replaced. They are able to be salvaged however and used with the service key, which doesn't need a battery to operate.
Immobiliser Systems
An immobiliser is a digital security device 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 electronic chip in your key responds with an individual code that must match the one found in the vehicle in order 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 chip that stores electronic security in a format that can't be duplicated. When your key or fob is placed in the ignition, it transmits the code to a receiver in the ECU. The ECU will then check it against the code that is stored in its memory and activates the ignition and fuel system circuit if they coincide. If the codes don't match, the engine will not start, even if an armed robber attempts to short-circuit the ignition circuit.
Replacing a lost or damaged key is a multi-stage process which involves precise cutting the new blade of the key and programming it to work with the immobiliser system of your vehicle. There are many different immobiliser systems used in different years and models and each has the use of a unique programming method.
