Raziel Most tubular locks out there are weak enough that with the right tools, they basically pick themselves. I think the point made by Taz is mostly that while most are like that, not all of them are. Many quite similar looking locks have very different degrees of security.
Now, those insertable locks that seem to be popular with cages for boys these days... I have the brand-name one, and it still opens with a random piece of metal and some careful jiggling.
