1997 Toyota 4Runner Owners Manual - Page 179

If you lose your keys Many Toyota dealers can make a new key if you can give them the key number. See the suggestion given in "Keys" in Chapter 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. 178
