Keys
Lexus keys aren't easy to replace. A specialist locksmith is needed to make an original replacement that works. This is because every Lexus key contains an embedded microchip that must be programmed in order to synchronise with the immobiliser of your vehicle in case it does not. If it doesn't, the vehicle will not be able to start.
This process requires time and special equipment to do properly, and each model has a distinct programing procedure. Replacing keys or remotes is a costly task that should be left to professionals, unless equipped with the right tools and knowledge.
It doesn't matter if you have a standard key that is turned on in the ignition barrel or a smart key that will start the car with the click of a button either way, they will need their batteries replaced. You can save money by doing this yourself, but it requires only a small Phillips screwdriver as well as the coin (a 20p piece works well) and a paperclip. You will find two or three screws on the back of the fob of the key. Remove them and keep them safe (they are small and easy to lose). Take lexus car key replacement TheKeyLab off to reveal an indentation of circular shape for the key made from metal, take the battery out (using the paperclip) and then insert the new battery, making sure it's the correct way up. Clip the inside of the key to secure it.
Remotes
Lexus remotes and fobs aren't easy to replace and require locksmiths who are both experienced and possess the proper tools. Certain models require that the transponder chip within the key be reprogrammed to function with the immobiliser of the car. The Lexus models employ different methods to program these chips. This is accomplished by using an electronic device that transmits an indication to the chip that matches the code used to unlock the doors and start the engine.
Certain Lexus vehicles are equipped with a device 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 little cheaper.
All fobs eventually lose their battery power, no matter the kind of key. This can be a frustrating experience, but it's possible to get your Lexus back up and running with a bit of know-how. Start by reading the owner's manual for the kind of battery you need and find a replacement. Find a small hole on the inside of the fob. Insert the coin (20p is a good choice) into the hole and then twist. The fob should be revealed as the flat spot, which you can utilize a paperclip to remove.
Then, pull the old battery out and insert the new one. Be sure to insert the battery with the correct direction of operation. Finally, you can clip the inside of the fob back together and re-insert the metal key.
Transponder Chips
More or less all new cars made since 1995 include transponder chips in the head of the key to disable the immobiliser system. If you've got a car key with a chip in it the head is covered in a plastic cover that can be pulled off to reveal an L-shaped metal key. Having a replacement key or fob that is made using transponder chips is a multi-stage procedure that involves precise cutting of replacement keys and programming of the transponder chip in order to synch up with the vehicle's immobiliser.
Transponders are electronic chip that has Non-Volatile Memory (NVM) which contains a set of windings (very fine wire twisted around tubes) which look similar to ones found in an electric motor. The windings create a coded signal for the car to read. If the code is valid, then the car will allow you to start it up.
There are two types of transponder chip, one known as the 80 bit and the other known as a circle + (General Motors). The first kind is reusable, however it needs to be removed using a special machine to function in a different vehicle that is compatible. The second one is more difficult to use as the old keys can be broken, drilled or thrown out when key cases are changed. They can be salvaged however for use with the service key, which does not require a battery to operate.
Immobiliser Systems
Immobiliser systems are electronic security devices that deter thieves from starting up your car. It operates by sending an electronic signal from the car to the key each time you attempt to start it. The chip inside the key responds with a unique code that must match the one in the vehicle to start. If the codes don't match, your engine will shut down immediately and prevent theft of your car.
Modern smart keys and fobs have an embedded transponder chip that stores electronic security in a format that cannot be duplicated. When your key or fob is put into the ignition, it transmits the code to a receiver within the ECU. The ECU will then check it against the code stored in its memory, and activates the ignition system and fuel circuit if they coincide. If the codes do not match, your engine won't start - even if an armed robber attempts to short-circuit the ignition circuit.
The process of replacing keys or fobs involves an entire process that involves cutting the new blade accurately and programming it to ensure that it works with the car's system. There are many different immobilisers used in different years and models and each has the use of a unique programming method.
