I asked in another thread about in-the-wall safes. I have decided to buy a real safe--free-standing--and simply secure it to the wall.
However, I was planning on buying one with an electronic lock for quicker access, but my wife asked me: "what happens if we get a huge solar flare, or an EMP burst? How will that affect your ability to get into the safe?" (what a great question)
I was just dumbfound-- I haven't got a clue.
Any of you electronics experts out there know the answer to this??
