Hockey Puck Locks




 These “hockey puck locks” commonly made by American Lock Company and Master Lock are starting to pop up all over. No matter who they are made by they all have the same design and specs. The common factor of these locks is that the shackle or pin is completely hidden. This disables you from using any kind of bolt cutters. An option I have seen done but never tried myself is by twisting these off with a pipe wrench. Possible I guess, if you are thinking far enough ahead to be carrying a pipe wrench. We tried prying with a halligan with little success and many of these are mounted with guards to prevent you from doing any type of prying. These are only as strong as their hasp, a weak one will be pried off easily with the lock still attached. What we show below is a specific cut using the demo saw with an abrasive blade.

 To start here is a few of the common uses and guards that these locks will be found on.


.  The most important step in making the right cut is finding the proper location. It is critical because you only have about a half inch area that this procedure can be done within to defeat the pin. Locate the keyway of the lock. You want to make your cut ¾ of the lock away from the keyway. This will effectively defeat the lock by cutting away the pin where it is exposed on its underside. The picture below is probably much clearer.


Once this cut is completed the lock may just fall of the hasp, or you may have to pull it off which should take nothing more than your hand. The picture below lets you see the underside of the lock and what you are defeating.

This allows you to see how they are attached underneath the lock.

The overall operation should only take you 20 to 30 seconds.
