This is accomplished by using a specific device that sends a code chip to unlock the doors or start the engine.

Certain Lexus models are built with a device that combines the key head and the remote. They are easy to replace because there is no separate chip to replace. This kind of key is also a bit cheaper.

If you've got a car key with a chip, the head is covered with a plastic cover that can be taken off to reveal an L-shaped key. A transponder chip replacement key or fob is a process that involves multiple stages. It involves cutting the keys accurately and programming the chip to communicate with the vehicle immobiliser.

A transponder is a device that has Non-Volatile Memory. It has a set of windings, which are very fine wires coiled around a tube. They look like those in an electric motor. The windings generate a coded message that the car is able to read. If the code is correct, the car will start.

There are two types of transponder chip, the one is known as the 80-bit and the other is called the circle + (General Motors). The first is reusable but must be delocked by a specific machine in order to work in another compatible vehicle. The second type is more difficult to use because the old keys can be broken, drilled, or thrown out when key cases are changed.

Immobiliser Systems

An immobiliser system is a digital security device that prevents thieves from starting your vehicle. It works by sending an electronic signal from your car to the key each time you attempt to start it.

When the fob or key are placed in the ignition, they send this code to the ECU. The ECU will then check it against the code stored in its memory and activates the fuel system and ignition circuit if they match. If the codes don't match, the engine won't be able to start - even if a thief tries to short-circuit the ignition circuit.
