I had a lockable case in my wife's jeep. It somehow got partially crunched beneath the passenger seat. It was a Nanovault 200. It was deformed in such a way that the key wouldn't turn. I thought it would be a good test to see how long it took me to get into it.

With a hammer and large flat screwdriver, it took me two to three minutes to get into it. And it was not subtle. As far as I am concerned that is good enough for me. It would certainly keep the casual thief from grabbing it. Sorry I did not try to cut the cable, but will do do to see if it will hold up...
