A long while ago I bought one of the Master brand boxes to store a

It only takes about 20 minutes to try them all...


Combination locks usually are set as 0000 as default. If you have lost it
and it's a 4 digit lock, , the combination is 10x10x10x10 or 10,000 posible
combinations - rather more that 20 mins I suspect.

Cheap combination locks are easy to suss

As was mentioned before, you can feel the positions if you put the lock
under a bit of pressure
