Keys
Lexus keys aren't always easy to replace. A specialist locksmith is required to create a spare that works. This is due to the fact that every Lexus key is equipped with an embedded microchip that must be programmed in order to synchronise with your vehicle's immobiliser and if it's not, it'll not start.

Remotes
Lexus remotes and fobs can be difficult to replace and require locksmiths who are both experienced and possess the proper tools. Some models require that the transponder chip contained in the key be programmed to function with the immobiliser of the car. The Lexus models use different methods to program these chips. This is done using a special device that sends an electrical signal to the chip that matches the code used to open the doors and start the engine.
Some Lexus vehicles are equipped with a unit that combines the key head and remote. They are simpler to replace since there is no separate chip required. This kind of key is also cheaper.

Transponder Chips
Transponder chips can be found in keys of nearly all new cars built since 1995. They can be used to disable immobiliser systems. If you've got a car key with a chip inside, the head comes with a cover that can be taken off to reveal an L-shaped metal key. The process of getting a replacement key fob made with a transponder chip is a multi-stage process that includes accurate cutting of the replacement keys and programming of the transponder chip to synch up with the vehicle's immobiliser system.
A transponder is an electronic chip that has Non-Volatile Memory (NVM) that houses a set of windings (very fine wire twisted around a tube) that look like the ones in an electric motor. These windings generate a signal 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 chip, one known as the 80 bit, and the other one is called a circle + (General Motors). The first is reusable, but must be unlocked with a special machine in order to work on a vehicle that is compatible with the. The latter is a bit more difficult as the old keys are often damaged and drilled or discarded when key cases are replaced. They can be salvaged however and used with a service key that doesn't need a battery to function.
Immobiliser Systems
An immobiliser is a security measure that uses electronic technology that deters thieves from starting your car. It works by sending an electronic signal from the car to the key every time you try to start it. The electronic chip in your key then responds with an individual code that must match that in the vehicle to start. If the codes don't match, your engine will immediately shut down to stop theft.
Modern smart keys and fobs contain an embedded transponder which stores electronic security information in a format that can't be copied easily. When your fob or key is inserted into the ignition, it transmits this code to a receiver in the ECU. The ECU then compares it to the code that is stored in its memory, and activates the ignition system and fuel circuit if the two coincide. If the codes do not match, your engine won't be able to start - even if a burglar tries to short-circuit the ignition circuit.
The process of replacing keys or fobs involves multiple steps that include cutting the new key blade with precision and programming it to ensure that it is compatible with your car's security system. There are many different immobiliser systems used in different models and years, and each requires its own distinct programming process.
