'01 TUNDRA_U (L/O 0008) If you lose your keys You can purchase a new key at your Toyota dealer if you can give them the key number. See the suggestion given in "Keys" in Section 1-2. If your keys are locked in the vehicle and you cannot get a duplicate, many Toyota dealers can still open the door for you, using their special tools. If you must break a window to get in, we suggest breaking the smallest side window because it is the least expensive to replace. Be extremely cautious to avoid cuts from the glass. 2001 TUNDRA (OM34416U) 223
