16. The lock assembly as claimed in claim 12 , further including a housing for the control component.
17. The lock assembly as claimed in claim 16 , wherein the housing is also adapted for storage of at least one battery or other power source.
18. A lock arrangement operable in both a right-handed door and a left-handed door, said lock arrangement comprising:
an orientation sensor adapted to indicate at least two spatial orientations of the orientation sensor; and
a controller adapted to interpret data, or control at least one lock component, in at least a first way, for use in the right-handed door, responsive to an indication of one of the at least two spatial orientations from the orientation sensor before or during installation of said lock arrangement and in at least a second way, for use in the left-handed door, responsive to an indication of the other of the at least two spatial orientations from the orientation sensor before or during installation of said lock arrangement;
wherein the indication of one of the at least two spatial orientations from the orientation sensor is automatic without actuation of the lock arrangement.
19. The lock arrangement as claimed in claim 18 , wherein the orientation sensor is adapted to indicate two spatial orientations of the orientation sensor.
