A disc tumbler lock having a code range angle, the disc tumbler lock including at least: at least one tumbler and a guard tumbler, the at least one tumbler and the guard tumbler defining a keyway aperture there through; wherein the at least one tumbler includes at least: a key engaging surface defining a key engaging zone, the key engaging zone having a first radius defining the major extent of the key engaging zone, and the key engaging zone having a second radius defining the minor extent of the key engaging zone; wherein the guard tumbler defines: a restrictive aperture comprising a restrictive width having a minimum dimension less than or equal to the sum of the first radius defining the major extent of the key engaging zone and the second radius of the minor extent defining the key engaging zone multiplied by the sine of one half of the following: the code range angle of the lock, minus the angular measure between a last code angle for the lock and a second to last code angle for the lock, minus the angular span of the key engaging surface.

The present invention, in a non-limiting example embodiment provides a locking apparatus and method for securing locking hardware without the use of a key. In an example embodiment, the apparatus comprises at least a keyless insertion rotatable disk-style, barrel locking apparatus that, in a locked state can be inserted into a securing device without first unlocking, and then, thereafter, locking after insertion. In a nonlimiting example embodiment, unlocking and re-locking requires a key. The present invention, in an example embodiment, also provides features that allow the locking apparatus to enter and exit multiple apertures without requiring a key.

A door hasp lock includes a first lock plate having a first flange and a first shield. A second lock plate is detachably engaged with the first lock plate and has a second flange detachably engaged with the first flange. The second lock plate has a third flange. The first lock plate and the second lock plate are engaged and disengaged when disposed at an operating locked state and a non-operating unlocked state, respectively. The third flange is spaced apart from the first flange and the second flange while the door hasp lock is disposed at both the operating locked state as well as the non-operating unlocked state. The third flange may be attached to either the first lock plate or second lock plate and has at least one feature that permits the third flange to break away from the second lock plate when tampered by an unauthorized user.

In one embodiment, the invention provides a lock body comprising a base portion and a moveable portion with each having first and second sides. One of the base portion second side and the moveable portion first side has an extension and the other having a receiver to allow the moveable portion to move translationally with respect to the base portion. A slot is transverse to the extension and cut into one of the face of the second side of the base portion or the first side of the moveable portion. In the open state the portions are separated and in the locked state the faces are substantially adjacent to capture a cylindrical object in the slot. In another embodiment, the lock body is cylindrical with a pair of transverse apertures. A plug inside the lock body moves translationally to capture an object between the apertures.
