Is the hide away just a piece of plastic that is covering the keyhole or did it replace the key hole all together? Anyways i would break that damn hideaway cover off and use your key to open the door. Its a no brainer but if the keyhole is comeplety missing then call a lock out person and they will try to pry your open a use a diagphram to open the door wide enough to put a rod through it and open the door that way. Good Luck!
