I am thinking about purchasing a little cheapo $50 safe. We have have a few items, car and boat titles, just a little cash we keep at the house for emergency, etc. Currently this stuff is in a drawer. I realize their fireproofedness(think I made up that word) is limited so my thought was to put it in the bottom of the freezer. Will that destroy the lock? My other thought was to get a gunsafe and put it in there, however my old neighbors house burned and inside his gunsafe there were no survivors, just some ash and bent metal.
