Certain Lexus vehicles are designed with a unit that combines the key head and remote. They are simpler to replace since there is no separate chip required. This kind of key may also be a little less expensive.

If you’ve got keys that has a chip inside it, the head is covered with a plastic cover that can be taken off to reveal an L-shaped metal key. Making a replacement key, or fob made of transponder chips is a multi-stage procedure that includes accurate cutting of the replacement keys and programming the transponder chip in order to synch up with the vehicle’s immobiliser system.

Transponders are electronic chip with Non-Volatile Memory (NVM) that houses a set of windings (very fine wire that is wrapped around tubes) that look like the ones in an electric motor. These windings create a coded message that the car is able to read. If the code is correct then the car will allow you to start it.

There are two types of transponder chip, the one is known as the 80-bit, while the second is known as the circle + (General Motors).

When the fob or key are inserted into the ignition, they transmit this code to the ECU. The ECU analyzes this code in comparison to the one that is stored in its memory, and then activates both the fuel system as well as the ignition circuit if they match.
