A resettable double-bit lock is disclosed, with a bolt having a resetting blade and a plurality of studded disks supported therein. The studded disks are adjacent a plurality of tumblers, the tumblers being supported pivotally around a mandrel and arranged by a double-bit key. A resetting swivel is supported on the bottom surface of the housing for the lock, with the resetting swivel being actuated by a bit of a resetting key and displacing thereby a resetting lock device. The resetting lock device includes a nose which releases a locking angle, the latter of which folding over into an opening position under a biassing force, which is preferably created by a spring. The locking angle further includes an arm so that when the bolt of the lock is pulled backwards, the resetting blade runs against the arm of the locking angle and releases the plurality of studded disks contained within the resetting blade.
