A door lock device includes a bolt 30 slidable in a housing 10 and a sliding deadlock 60 having two deadlocking members 61, 62 on each side of a compartment 64 into which the bolt can be retracted. A moving device 50 for the deadlock can be mounted using fasteners 18, 19 engaging selected housing apertures 15, 16 and 17 so as to locate the members 61, 62 in two alternative positions relative to the bolt 30 (figs. 3 and 6) and includes an electromagnetic mechanism 51 powered to extend a core 56. In one mounting position the mechanism 51 is normally powered-off and member 62 blocks bolt retraction - the application of power extends the core 56 and aligns compartment 64 to allow retraction (fig. 3). In the other mounting position the power is normally on to extend the core 56 and member 61 blocks bolt retraction (fig. 6) - when the power is off the compartment 64 aligns with the bolt to allow retraction. A spring 35 acts to urge the bolt 30 to the extended position and the bolt has two inclined faces to allow different-handed door operation.
