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. 11L025a We recommend that you write down the key number and keep it in a safe place. 1 Master key (black) - The master key works in every lock. For your Lexus dealer to make you a new key with built-in transponder chip, your dealer will need it. Sub key (gray) - The sub 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 immobiliser system has been filled 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. To protect items locked in the glove box when someone else parks your vehicle for you (such as an attendant or valet), leave the sub key with them. 8
