Housing for electronic lock

A housing assembly adapted to fit into a mortised recess formed in an edge of a door for accommodating components of an electronic lock mechanism including the electronic circuitry for operating the lock mechanism, the housing assembly comprising:

• a housing including opposed major side walls at least partially defining an opening into the housing;
• a circuit board disposed in the housing, the circuit comprising electronic circuitry for operating the lock mechanism;
• a bracket for holding batteries, the bracket adapted to be disposed in the opening in the housing;
• and
• means for electrically connecting the bracket and the circuit board,
• wherein the bracket is accessible when the housing is in the mortised recess of the door, the bracket movable relative to the housing between a first position and a second position so that in the first position the bracket is in the housing and in the second position the bracket is at least partially outside of the housing such that batteries may be inserted into or removed from the bracket.
