1997 Lexus SC 400 Owners Manual - Page 17

KEYS AND DOORS KEYS Master key - The master key works in every lock. Subkey - The subkey will not open the trunk, trunk main switch and the glovebox. Key number plate - Keep the plate in a safe place such as your wallet, not in the vehicle. To protect things locked in the trunk or glovebox when you have your vehicle parked, leave the subkey 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 require replacement or additional keys for any reason, contact your Lexus dealer. You should also put a copy of the key number with your important papers. 8 Insert your flat key in its key case as shown. We recommend that you always carry this with you as a spare. Do not leave it in your vehicle. NOTICE S Do not let the key case become bent as the key may fall out or become bent also. S The flat key is designed for emergency use only.
