The standard, Master
style combination locks
are simply constructed. A steel
catch with an internal locking mechanism. To unlock said mechanism, one must grasp the dial firmly with one's fingers
and turn it completely a few times clockwise
. This is done to reset the pins, tumblers, etc. inside. Once again turn clockwise, to the first number in the combination
. Upon reaching said number, turn the dial counterclockwise
once completely, passing the second number of the combination. Continue turning counterclockwise until you again reach the second number in the combination. Stop
here. Turn clockwise once again until you reach the final number in the combination. Do not pass it.
Pull down firmly on the body of the lock, and with any luck at all, the casp will release.
(This is also a neat instrumental Fugazi song on the album Red Medicine.)
