Re: Metal door
We had a mainframe room "upgraded" from high security key lock (which were good enough that I struggled to pick them) to an RF fob lock and one of those big magnetic latches. This was supposed to be for better security (with entry logs) for a high profile project. I demonstrated that I could open the new door either by flicking a mcb on the breaker panel (it was held shut with an active magnet, so fail open) or a really solid shoulder barge (once you opened up a small gap, the magnetic force drops off pretty sharply).
The new system was quickly replaced by some good high security physical locks...
