A replacement key or fob with a transponder chip is a multi-stage procedure that includes accurate cutting of the replacement keys as well as programming the transponder chip to synch up with the vehicle's immobiliser.
A transponder is a type of chip with Non-Volatile Memory. It has a set windings, which are very fine wires that are wrapped around the tube. They look like those in an electric motor. These windings generate a signal that the car can read. If replace lexus key is valid, then the car will allow you to start it.
There are two types of transponder chips. The first is called the 80-bit and the other is known as the circle + (General Motors). The former can be reused but it needs to be unlocked by a special machine to be used in a compatible vehicle. The latter is more difficult, as the older keys are often damaged or drilled through, or thrown away when key cases are replaced. However, they can be utilized with a service key that does not require a battery.
Immobiliser Systems
Immobiliser systems are electronic security devices which prevent thieves from starting up your vehicle. It works by sending a signal from your vehicle to the key when you attempt to start it. The chip inside the key responds with a unique code that must match that in the vehicle to start. If the codes don't match, the engine will shut off immediately to prevent theft.
Modern smart keys and fobs come with an embedded transponder which stores electronic security information in a format which cannot be 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 stored in its memory, and it activates both the fuel system as well as the ignition circuit if they are compatible. If the codes do not match, the engine won't start - even if someone tries to short-circuit the ignition circuit.
