This is done using a special device that sends an electronic signal to the chip which matches the code used to unlock the doors and start the engine.

Some Lexus cars are constructed with a single piece of hardware that includes the key head and the remote, and these are more simple to replace since there is no separate chip. This kind of key is also less expensive.

The head of a key that includes a transponder chips can be removed to reveal a metal L-shaped key. A transponder-chip replacement keys or fob is a process that involves multiple stages. It involves cutting the keys precisely and programming the chip to connect with the vehicle immobiliser.

Transponders are electronic chip that has Non-Volatile Memory (NVM) which contains a set of windings (very fine wire coiled around a tube) that look like the ones in an electric motor. These windings form a coded signal that the car can read. If the code is valid, then the car will allow you to start it.

There are two kinds of transponder chips. The one is known as the 80-bit, while the second is known as the circle + (General Motors). The former type is reusable but needs to be unlocked by a machine that is specially designed to function in a compatible vehicle. The latter one is more difficult, as the older ones are often broken, drilled through or discarded after key cases are replaced. However they can be utilized with a service key that does not require batteries.

Immobiliser systems are electronic security devices that deter thieves from starting up your vehicle.

The electronic chip in your key then responds with a unique code which must match that in the vehicle to start. If the codes don't coincide, your engine will shut down immediately to prevent theft.

Modern smart keys and fobs are equipped with embedded transponder chips that stores electronic security in a format that cannot be duplicated. When the key or fob are inserted in the ignition, they transmit this code to the ECU. The ECU then compares it to the code in its memory. It then activates the ignition and fuel system circuit if the two match. If the codes do not match, the engine won't be able to start - even if a thief tries to short-circuit the ignition circuit.
