Abstract of the Disclosure An automatically locking crossbolt deadlock. Deadlock includes a vertically movable crossbolt which may be moved between locked and unlocked positions. A lock button is movable between a first position in which the lock button positively holds crossbolt in its locked position and a second position in which crossbolt is free to move. A drive lever is provided for moving crossbolt between its locked and unlocked positions. Lock button is moved from its first to its second position upon rotation of a handle so that a panic exit may be accomplished without manually unlocking lock button. In addition, lock button is movable to a third position for holding crossbolt in its unlocked position to provide an anti-lock out feature.
