Description & Operation: Keys: Notes
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.
