Lexus Key Replacement - Replacing a Remote Or Fob
The battery in your key fob will eventually go out, whether you own a conventional Lexus Key that turns on the ignition, or an intelligent key for your vehicle, which starts by pressing a button. Replacing it is as simple as a paperclip: Pop the existing battery out and then insert the new one (refer to the owner's manual to see which type of battery you need) and then clip it back into place.
Keys
Lexus keys aren't easy to replace and require a specialist locksmith for replacing car keys to make a functioning spare. Every Lexus key is equipped with an embedded microchip, which needs to be programmed in order to work with the immobiliser system in your vehicle.
It takes a lot of time and equipment that is specially designed for this process to be carried out correctly. Each model comes with its own set of programming procedures. Replacing a key or a remote fob can be a costly task and should be left to professionals unless you have the right tools and know-how.
It doesn't matter if you have a standard key that turns in the ignition barrel or a smart key that will start your car at the click of one button Both will eventually require their batteries replaced. It's easy to do it yourself however, you'll require an inexpensive Phillips Screwdriver, a 20p coin and paperclip. There are two or three screws on the back of the fob for the key. Remove them and store them securely (they are small and easy to lose). Take the fob off to reveal an indentation of circular shape for the key made of metal. Take the battery out (using the paperclip) and insert the new battery, making sure it is the right way up. Then clip the inside of the key back together.
Remotes
Replacing a Lexus remote or fob is complicated and requires expert locksmiths with both the right tools as well as knowledge. Some models require the transponder within the key to be reprogrammed in order to function with the immobiliser systems of the car. These chips are programmed using different methods based on the model of Lexus. This is done 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 cars are equipped with a single piece of hardware which includes the key head and the remote. These are more simple to replace since there is no separate chip. This type of key can also be a little less expensive.
All fobs eventually lose battery power, regardless of the type of key. This could be a difficult experience, but it is possible to get your Lexus back in operation with a little bit of knowledge. First, check the owner's manual for the kind of battery you need and find a replacement. Find a small hole on the inside of your fob. Insert the coin (20p is a good choice) into the hole and twist. The fob should be revealed as a flat area that you can utilize a paperclip to remove.
Then, pull the old battery out and insert the new one. Make sure that you insert the battery with the proper direction of operation. Clip the two sides of your fob together and insert the key metal.
Transponder Chips
Transponder chips can be found in key heads of a majority of new cars built since 1995. They can be used to disarm immobiliser systems. If you've got a key with a chip inside, the head is covered in a plastic cover that can be taken off to reveal an L-shaped metal key. Having a replacement key or fob made with transponder chips is a multi-stage process that includes precise cutting of replacement keys as well as 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 contains a set of windings (very fine wire coiled around the tube) that resemble ones in an electric motor. These windings produce a coded message that the car can read. If the code is valid, then the car will allow you to start it.
There are two types of transponder chip, the one is known as the 80-bit while the other is called the circle + (General Motors). The first is reusable however it must be unlocked with a special device to function in a different compatible vehicle. The second is more difficult to use as the older ones could be broken, drilled, or thrown out when key cases are changed. However, they can be used with a key-service that doesn't require a battery.
Immobiliser Systems
Immobiliser systems are electronic security devices that prevent thieves from starting up your vehicle. It operates by sending an electronic signal from the vehicle to the key whenever you attempt to start it. The electronic chip inside the key responds with an individual code that must match that of the vehicle in order to start. If the codes aren't compatible, the engine will shut down immediately and stop the theft of your car.
Modern smart keys and fobs contain an embedded transponder that stores electronic security information in a format which is not easily copied. When the fob or key is inserted into the ignition, they transmit this code to the ECU. The ECU is able to compare this code with the one that is stored in its memory, and it activates both the fuel system and the ignition circuit if they are compatible. If the codes do not match, the engine will not start, even if an armed robber attempts to short-circuit the ignition circuit.
