    OK - so I have this rather heavy copy-paper cabinet that also was built to be a laser printer stand.

    I'm thinking, "Hey! This might make a light-duty safe - if I could lock it up somehow".

    So I find this nifty keen part from Maxim that should fill the bill to a tee.

    The only problem is it's in a microscopic SMD package!
