Keys

Remotes
Replacing a Lexus remote or fob can be a complicated process and requires skilled locksmiths equipped with the right tools and expertise. Some models require the transponder inside the key to be programmed to allow it to communicate with the immobiliser of the vehicle. The Lexus models employ different methods to program these chips. This is done using an electronic device that transmits a signal to the chip that matches the code used to unlock the doors and start the engine.
Some Lexus cars are constructed with a single unit that incorporates the key head as well as the remote. These are much easier to replace because there is no separate chip. This kind of key could also be a bit cheaper.

Transponder Chips
Nearly all new cars made since 1995 include transponder chips inside the key head that allow it to deactivate the immobiliser system. The head of a key which has a transponder chip can be removed to reveal a metal L-shaped key. A replacement key or fob made of a transponder chip is a multi-stage method that includes accurate cutting of the replacement keys and programming the transponder chip to link up with the vehicle's immobiliser.
A transponder is a device that has Non-Volatile Memory. It is comprised of a set of windings which are fine wires wrapped around a tube. They look like the ones in an electric motor. The windings are coded to create a signal for the car to read. If the code is correct then the car will allow you to start it.
There are two types of transponder chips. One called the 80 bit and the other referred to as a circle + (General Motors). The former can be reused however it must be unlocked by a specific machine in order to function in a different compatible vehicle. The latter is more difficult since the earlier keys are often damaged and drilled or discarded when key cases are replaced. However, they can be used with a service-key which doesn't require a battery.
Immobiliser Systems
An immobiliser system is an electronic security measure that deters thieves from starting your car. It operates by sending an electronic signal from your car to the key every time you attempt to start it. The chip inside the key responds by transmitting a unique code that must match that of the vehicle to allow it to start. If the codes don't match, your engine will stop immediately, preventing theft of your vehicle.
Modern smart keys and fobs contain an embedded transponder, which stores electronic security information in a format which is not easily copied. When your key or fob is placed in the ignition, it transmits this code to a receiver within the ECU. The ECU then compares it with the code stored in its memory and then activates the ignition and fuel system circuit if they coincide. If the codes don't match, the engine won't be able to start - even if an armed robber attempts to short-circuit the ignition circuit.
Replacing a fob or key is a multi-stage procedure that involves accurate cutting of the new key blade, and programming it to synch with your car's immobiliser system. Each immobiliser system is unique and has its own programming procedure. We use Ross-Tech software to ensure that your replacement key is programmed correctly for maximum performance and security.
