These chips are programmed by different methods depending on the model of Lexus.

If you've got keys with a chip inside, the head has a plastic cover which can be pulled off to reveal an L-shaped key. Making a replacement key, or fob made of transponder chips is a multi-stage process that includes accurate cutting of the replacement keys and programming the transponder chip to synch up with the vehicle's immobiliser.

A transponder is an electronic chip equipped with Non-Volatile memory (NVM) that houses a set of windings (very fine wire twisted around the tube) that resemble ones in an electric motor. These windings transmit a message that the car is able to read. If the code is correct, the car will start.

There are two kinds of transponder chip. The one is known as the 80-bit, while the second is known as the circle + (General Motors). The former can be reused however it must be unlocked by a special machine to function in a different compatible vehicle. The second one is more difficult to use as the old keys can be damaged, broken or taken away when key cases are changed. They are able to be salvaged however and then used to create an ad-hoc key that doesn't require batteries to operate.

Immobiliser Systems

Immobiliser systems are electronic security devices that prevent thieves from starting up your vehicle. It operates by sending a signal from your car to the key when you attempt to start it. The electronic chip in the key responds by sending a unique code that must match that of the vehicle to allow it to start. If the codes do not match, your engine will shut off immediately to stop theft.

Modern smart keys and fobs have an embedded transponder which stores electronic security information in a format which cannot be easily copied. When the fob or key are inserted into the ignition, they transmit this code to the ECU. The ECU then compares it with the code in its memory, and activates the fuel system and ignition circuit if they match. If the codes do not match, your engine will not start, even if a thief tries to short-circuit the ignition circuit.

The replacement of keys or fobs involves a multi-stage process that includes cutting the new blade precisely and programming it to ensure that it is compatible with your car's security system.
