Abstract: A high security lock apparatus comprises a deadbolt lock (70) having a lock body (71) and a deadbolt (73) extendible therefrom. A lock body support (67) cooperates with the lock body (71) to permit relative movement therebetween and has a deadbolt clearance opening (81) therein to receive the deadbolt (73) when aligned therewith. A doorbolt is operatively connected to the lock body support (67) and mounted for movement with respect to a complementary doorbolt stop in response to the relative movement. A tool receiver (77) cooperates with the lock body support (67) and receives an alignment tool (101) to generate the movement to align the deadbolt (73) with the deadbolt clearance opening (81) prior to extending the deadbolt (73). Preferably, the lock body (71) is journalled for rotation relative to the lock body support (67).
