Description & Operation: Keys: Notes

WARNING: This page is about a different car, the 2002 Lexus GS 430 and 2002 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Duplicate keys must be made at a Lexus dealer, because a built-in transponder chip is needed to cancel the system or start the engine.

The types of keys are:

Master key (Black)

The master key works in every lock.

Sub-key (Gray)

The sub-key will not open the trunk, trunk main switch and glove box.

Flat key

As a transponder chip is built in it's key case, you can start the engine with this key. The flat key works in every lock.

A transponder chip for the engine immobilizer system has been filled in the head of the master and sub-keys and in the key case of the flat key. These chips are needed to enable the system to function correctly.
