'03Camry_U (L/O 0208) 2. Sub key (gray)- This key will not work in the glove box and trunk. To protect items locked in the trunk or glove box when using valet parking, leave the sub key with the attendant. A transponder chip for engine immobiliser system has been fitted in the head of the master and sub keys. These chips are needed to enable 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. 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 with other transponder keys around (including keys of other vehicles) and do not press other key plates against the key grip. Otherwise the engine may not start, or may stop soon after it starts. If this happens, remove the key once and then insert it again after taking off other transporter keys (including keys of other vehicles) from the ring or while gripping or covering them with your hand to start the engine. 2003 MY CAMRY (OM33569U) 11
