Description & Operation: Keys: Notes
WARNING: This page is about a different car, the 2002 Lexus ES 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 glove box and rear armrest door in the rear seat. - 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 installed 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.
