07 04.26 Keys (without engine immobilizer system) Keys (with engine immobilizer system) XS12045 XS12046 XS12049 These keys work in every lock. Your vehicle is supplied with two kinds of keys. 1. Master keys-These keys work in every lock. 2. Sub key-This key will not work in the glove box and tailgate. To protect items locked in the glove box when using valet parking, leave the sub key with the attendant. Since the side doors can be locked without a key, you should always carry a spare key in case you accidentally lock your keys inside the vehicle. KEY NUMBER PLATE Your key number is shown on the plate. Keep the plate in a safe place such as your wallet, not in the vehicle. If you should lose your keys or if you need additional keys, duplicates can be made by a Toyota dealer using the key number. We recommend writing down the key number and storing it in a safe place. Your vehicle is supplied with the two kinds of keys. 1. Master keys (black)-These keys work in every lock. Your Toyota dealer will need one of them to make a new key with a built −in transponder chip. 2. Sub key (gray)-This key will not work in the glove box and tailgate. A transponder chip for engine immobilizer system has been placed 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. 18 2007 TUNDRA from Jul. '07 Prod. (OM34463U)
