Hello all, I was just playing with the magiclocker and holytrainer - and I found out that it is actually possible to lock without using the key. The twistable part of the magic locker is actually slanted, which means it is possible to insert it in, in the locked form, without the key, but not retrieving it. I'm not sure if the real magic locker is like this, since this is a House of Denial clone. But I haven't seen anyone mention this before, so I assume this would help some people.
There's probably some give with the plastic devices, and who knows how closely the Chinese clone locks are held to the original size. I certainly can't do this with the steel device that I wear.
