Your locks could be rendered all but useless if your keys get out of sight for just a minute. And the would-be thief doesn't need to be a master lockpick: all he needs is an iPhone.

Keys have never been the best form of security, but with technology like this around, you might want to think twice before handing your set over to someone else.
