1998 Toyota Avalon Owners Manual - Page 8

'98 AVALON (USA/CANADA) −U Keys (with engine immobiliser system) Your vehicle is supplied with the two kinds of key. Master key (black)-This key works in every lock. Your Toyota dealer will need it to make you a new key with built −in transponder chip. Subkey (gray)-This key will not work in the glovebox and trunk. The master key and subkey each have a transponder chip in their key head which is very important for the system function, 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 things locked in the glovebox or trunk 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. NOTICE When using a key containing a transponder chip, observe the following precautions: z When starting the engine, do not use the key with a key ring resting on the key grip and do not press the key ring against the key grip. Otherwise the engine may not start, or may stop soon after it starts. z When starting the engine, do not use the key in contact with another transponder key (including keys of other vehicles) and do not press another key plate against the key grip. Otherwise the engine may not start, or may stop soon after it starts. 8
