Alternative Snapping | Locksmith Blog
It seems that every crook out there seems to know about lock snapping.

The companies scaremongering the public into upgrading locks put the technique right in the spotlight and i can honestly say i saw the number of lock snap related break ins double if not triple.

However they dont always get in.
I came across this lock mullered in a door a few months ago and had to improvise since picking was well and truly out of the question.

As i have never dug deep and purchased a plug puller tool I decided to drill for the retaining screw and hope to snap the lock using a bit of leverage with the aid of a tight fitting screwdriver down the drill hole.

30 seconds of jiggling and the weak metal finally gave way and out popped the cylinder half.

Its a technique iv heard about in the past but never really been in a situation that allowed me to test it.

In fact theres even a small tools company selling the Rod Based Snapper for this very purpose.


I had a spare half hour today and was playing with some locks and decided I would document a flaw with some of the cheaper antisnap locks on the market.

What i have noticed with companies designing locks that 'tick all the boxes' is that they can actually reduce the overall security of the lock.

This particular one made by UAP (BS Rated?) all singing and dancing anti drill/snap/pick euro cylinder.

However you will notice that all 'anti drill' properties are contained within the sacrificial portion of the lock.
Eliminate that portion and its game over.
If this particular lock has been awarded a BS rating it should most certainly be stripped of it!

I know it would be easy enough to pick the remaining 3 pins for anyone half capable...

However since i had no anti drill pins to wreck a £3+ hardplate bit i decided to snap this in the same method as I used on the vandalised Zone cylinder i encountered on the job above. 
Just for fun :-)
