Lexus Key Replacement - Replacing a Remote Or Fob
If you have a traditional Lexus key that switches on the ignition, or a smart key for your car, which starts with the push of an arrow, eventually the battery in the fob will deplete. It's simple to replace it using the help of a paperclip. Simply remove the old battery, insert the new battery (refer to the owner's manual to determine the type of battery that you need), then clip it back in the correct position.
Keys
Lexus keys aren't always easy to replace. A professional locksmith is required to create an appropriate replacement that functions. This is due to the fact that every Lexus key has an embedded microchip that must be programmed to synchronise with the immobiliser system of your vehicle - if not it will not be able to start.
It takes a lot time and specialized equipment to allow this process to be carried out correctly. Each model has its own specific programming process. Replacing a remote or key fob is an expensive service and one you should leave to professionals unless your have the appropriate tools and expertise.
If you have a traditional key that turns in the ignition barrel or a smart key that can start the car with the click of an arrow Both will eventually require their batteries replaced. It's a simple task to do, but you will need an inexpensive Phillips Screwdriver, 20p coin and paperclip. On the back of the fob you will see two or three screws loosen them and place them somewhere safe (they're small and can be lost). Remove the fob, revealing an indentation that is circular where the key's metal surface will be. Remove the battery with the help of a paperclip. Insert the new battery, making sure that it's properly inserted. Clip the the key to secure it.
Remotes
Replacing a Lexus remote or fob can be complicated and requires skilled locksmiths with the right tools as well as knowledge. Some models require the transponder on the key to be changed so that it can work with the immobiliser of the vehicle. These chips are programmed by different methods based on the model of Lexus. This is done with an electronic device that transmits an indication to the chip that is compatible with the code used to unlock the doors and start the engine.
Certain Lexus cars are designed with a single piece of hardware that consists of the key head and remote. These are simpler to replace as there is no separate chip. This kind of key could also be a bit less expensive.
Whatever the type of key regardless of the type of key, all fobs eventually run out of battery power. It can be quite frustrating, but with a little know-how you can get your Lexus back to normal. The first step is to consult the owner's manual to identify the type of battery you need and then locate a replacement. Then, locate tiny holes on the inside of the fob. insert the coin (a 20p piece is a good choice) and twist. This should reveal a flat spot that you can employ a paperclip to take away.
Next, pop the old battery off and insert the new one. Be sure the replacement battery is inserted with the correct orientation. Clip the inside of your fob together and insert the key in the metal.
Transponder Chips
Transponder chips are in the keys of nearly all new cars built since 1995. They are used to disarm immobiliser systems. The head of a key which is equipped with a transponder chip may be removed to reveal an L-shaped key. Having a replacement key or fob made with transponder chips is a multi-stage method that includes precise cutting of key replacements and programming the transponder chip to synch up with the vehicle's immobiliser system.
A transponder is an electronic device with Non-Volatile Memory (NVM) that has a set of windings (very fine wire coiled around tubes) that look like the ones found in an electric motor. The windings generate a coded message that the car can read. If the code is valid, then the car will allow you to start it up.
There are two types of transponder chips. One is called the 80 bit and the other referred to as a circle + (General Motors). The first is reusable, but must be delocked using a specific machine to function in a different vehicle that is compatible. The latter is more difficult, as the older keys are often damaged or drilled through, or discarded after key cases are replaced. However, they can be used with a service-key that does not require batteries.
Immobiliser Systems
An immobiliser system is a security measure that uses electronic technology which prevents thieves from opening your vehicle. It operates by sending an electronic signal from the vehicle to the key whenever you attempt to start it. The electronic chip in your key responds by sending a unique code that must match that in the vehicle to start. If the codes do not match, the engine will shut off immediately to stop theft.
Modern smart keys and fobs are equipped with an embedded transponder chip that stores electronic security in a format that can't be easily duplicated. When the fob or key are inserted into the ignition, they transmit this code to the ECU. The ECU then compares it with the code that is stored in its memory, and activates the fuel system and ignition circuit if the two match. If the codes do not match, your engine will not start, even if a burglar tries to short-circuit the ignition circuit.
The process of replacing the fob or key requires a multi-stage procedure that includes cutting the new blade with precision and programming it so that it syncs with your car's systems. There are many different immobiliser systems used in different models and years and each needs its own unique programming procedure.
