Keys
Lexus keys aren't easy to replace and require a professional locksmith for car keys to create a spare working.

Clip the inside of the metal key back together.
Remotes
Lexus remotes and fobs aren't easy to replace and require locksmiths who are both well-versed and have the proper tools. replacement lexus key fob require the transponder on the key to be reprogrammed in order to function with the immobiliser of the vehicle. The Lexus models employ different methods to program these chips. This is done by using an instrument that sends a signal to the chip which matches the code used to unlock the doors and start the engine.
Some Lexus cars are designed with a single unit which includes the key head as well as the remote, and these are much easier to replace because no separate chip is required. This type of key is also a bit cheaper.

Transponder Chips
Nearly all new cars since 1995 have transponder chips embedded in the head of the key to disable the immobiliser system. If you've got keys with a chip inside, the head comes with a cover that can be taken off to reveal an L-shaped key. Having a replacement key or fob made of transponder chips is a multi-stage process that includes precise cutting of replacement keys and programming the transponder chip so that it can synch up with the vehicle's immobiliser.
A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that has a set of windings (very fine wire wrapped around the tube) that resemble ones found in an electric motor. These windings form a coded signal that the car can read. If the code is correct it will allow the car to start.
There are two types of transponder chip. The first is called the 80-bit and the second is known as the circle + (General Motors). The first type can be reused, but has to be delocked using a specific machine in order to work on a vehicle that is compatible with the. The second type is more difficult to use due to the fact that the older ones could be broken, drilled, or taken away when key cases are changed. They can be salvaged however, to use with the service key, which does not require a battery to operate.
Immobiliser Systems
An immobiliser is a digital security device which prevents thieves from opening your vehicle. It works by sending an electronic signal from the car to the key whenever you attempt to start it. The chip inside the key responds by sending a unique code which must match the one of the vehicle to allow it to start. If the codes don't coincide, your engine will immediately shut down to stop theft.
Modern smart keys and fobs contain an embedded transponder that stores electronic security information in a format which is not easily copied. When the key or fob are inserted into the ignition, they transmit this code to the ECU. The ECU analyzes this code in comparison to the one in its memory, and then activates both the fuel system as well as the ignition circuit if they are compatible. If the codes don't match, the engine will not start even in the event that the ignition circuit is damaged by a thief.
