Keys
Lexus keys can be difficult to replace. A professional locksmith is required to design an original replacement that works. This is because each Lexus key has a microchip that needs to be programmed in order to synchronise with the immobiliser of your vehicle If it is not, the car will not start.
It requires a lot time and specialized equipment to allow this process to be carried out correctly. Each model comes with its own set of programming procedures. Replacing a remote or key fob is an expensive service and should be left to experts unless you have the right tools and know-how.
If you have a traditional key that turns on the ignition barrel or a smart key that starts the car with the click of a button, both will eventually need their batteries replaced. This can be done by yourself, but you will need the smallest Phillips Screwdriver, 20p coin and a paperclip. You will find two or three screws on the back of the fob that holds the key. Remove them and store them securely (they are small and easy to lose). The fob is removed, revealing a circular indentation where the key made of metal will be. Pop the battery out with the paperclip, and then insert the new battery, making sure that it's inserted correctly. Clip the inside of the metal key back together.
Remotes
Lexus remotes and fobs can be difficult to replace and require locksmiths who are experienced and possess the proper tools. Certain models require that the transponder chip contained in the key be reprogrammed to function with the immobiliser of the car. The Lexus models use different methods to program these chips. This is done by using a specific device that sends a signal to the chip which matches the code used to unlock the doors and start the engine.
Certain Lexus vehicles are designed with a device that combines the key head and the remote. They are easy to replace, since there is no separate chip needed. This kind of key is also a bit cheaper.
All fobs eventually lose battery power, no matter the kind of key. It can be frustrating but with a little bit of knowledge you can get your Lexus up and running. Refer to the owner's manual to determine what type of battery you need. Then, find the replacement. 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. This should reveal a flat area that you can make use of a paper clip to take away.
Next, pop The Key Lab out and replace the new one. Make sure to insert the battery with the correct direction of operation. Finally, you can clip the inside of the fob back together and reconnect the key to the metal.
Transponder Chips
More or less all new cars since 1995 have transponder chips inside the key head that allow it to deactivate the immobiliser system. The head of a key which is equipped with a transponder chip may be removed to reveal a metal L-shaped key. A transponder chip replacement key or fob is a multi-stage process. It involves cutting the keys with precision and programming the chip to connect with the vehicle's immobiliser.
A transponder is an electronic chip that has Non-Volatile Memory (NVM) that houses a set of windings (very fine wire that is wrapped around a tube) which look similar to ones found 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 kinds of transponder chip. The one is known as the 80-bit, while the second is called the circle + (General Motors). The former is reusable however it must be unlocked by a specific machine in order to function in a compatible vehicle. The second type is more difficult to use because the older ones could be broken, drilled or taken away when key cases are changed. They are able to be salvaged however, to use with an ad-hoc key that doesn't require batteries to function.
Immobiliser Systems
Immobiliser systems are electronic security devices that deter thieves from starting your vehicle. It operates by sending a signal from the vehicle to your key when you attempt to start it. The electronic chip in your key then responds with a unique code which must match that of the vehicle in order to start. If the codes don't coincide, your engine will stop immediately to stop theft.
Modern smart keys and fobs are equipped with embedded transponder chips that stores security information in a format that can't be duplicated. When your fob or key is put into the ignition, it transmits this code to a device within the ECU. The ECU will then check it against the code stored in its memory, and activates the ignition and fuel system circuit if they coincide. If the codes don't match, the engine won't start - even if a burglar tries to short-circuit the ignition circuit.
The process of replacing the fob or key involves a multi-stage process that includes cutting the new key blade with precision and programming it so that it works with your car's security system. There are a variety of immobilisers that are available in various years and models and each needs its own unique programming procedure.
