2005 Lexus LX 470 Owners Manual - Page 32

KEYS AND DOORS KEYS Since the side doors and back door 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. 11x503 We recommend writing down the key number and storing it in a safe place. 1 Master keys (black) - The master keys work in every lock. For your Lexus dealer to make you a new key with a built-in transponder chip, your dealer will need it. Valet key (gray) - The valet key will not open the glove box. 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 valet 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. To protect items locked in the glove box when using valet parking, leave the valet key with the attendant. 8
