2004 Lexus LS 430 User Guide 2 - Page 32

KEYS AND DOORS Vehicles not equipped with smart key system (Type B) To protect items locked in the trunk or glove box when using valet parking, leave the sub key with the attendant. Since the doors and trunk lid can be locked without a key, you should always carry a spare master key in case you accidentally lock your keys inside the vehicle. If you should lose your keys or if you need additional keys, duplicates can be made by a Lexus dealer using the key number. We recommend writing down the key number and storing it in a safe place. 11L025c 1 Master keys (black) - These keys work for every lock. For your Lexus dealer to make a new key with a built-in transponder chip, your dealer will need one of them. Sub key (gray) - This key will not open the trunk, trunk main switch, the glove box and trunk storage extension door. Key number plate - Keep the plate in a safe place such as your wallet, not in the vehicle. 2 3 A transponder chip for the engine immobilizer system has been placed in the head of the master and sub keys. These chips are required for the system to function correctly, so be careful not to lose these keys. If you make your own duplicate key, you will not be able to cancel the system or start the engine. 14
