1. A lock mechanism, comprising:
a bolt movable between a thrown position and a retracted position; and a deadbolt assembly comprising:
a sliding deadbolt configured to slide between a locked position in which the sliding deadbolt inhibits retraction of the bolt and an unlocked position, the sliding deadbolt comprising a first anti-thrust cam configured to restrain the sliding deadbolt in the locked position, and
a release driver arranged such that, when driven, the release driver releases the first anti-thrust cam from restraining the sliding deadbolt in the locked position and slides the deadbolt to the unlocked position wherein the first anti-thrust cam is a receiver and the deadbolt assembly is a detent attached to a casing part of the deadbolt assembly, and when the first anti-thrust cam restrains the sliding deadbolt in the locked position the receiver engages the detent.
