Virtually everyone carries keys. That is not a problem until we misplace them. Most of us have experienced the problem of 'putting our keys down somewhere' and rushing around trying to find them. Mostly we'll find them, but what happens when we can't? Suddenly we're faced with having to not only cut new keys, but if there's a chance that the keys have been stolen you would have to replace the locks as well. This could cost hundreds of dollars, if not thousands!! The Register helps remove this problem.
