How many have you found yourself locked out, stuck with a visiting friend who has to wait on the curb cause you aren't able to get them a key yet, left out in the cold with a lost key and locksmith, or any number of other unfortunately common circumstances? As long as people use physical keys—we're going to run into some unfortunate problems. And while KeyMe won't solve all of those, it comes as close as you're going to get for now.
What does it do?
Takes a scan of your house key and generates coded instructions that any locksmith or key maker will be able to read, so you can make a copy of your key anywhere in the world, no matter what situation you find yourself in. The code contains one line that instructs with blank to start with and another line with a series of numbers that dictate the depth of the key's teeth. Once you've saved your key, you can even share the instructions with a friend if need be.
Why do we like it?
Getting in once you've found yourself locked out can be preposterously expensive—but normally you have no other choice but to cough up the dough. Now, though, assuming you have the foresight to store your keys' info, you'll be ready to go without paying a ridiculous price, and you won't even have to spend time waiting for the locksmith. Scanning the key is free, but retrieving the information to make a new one costs $10, which isn't cheap, sure, but it's still a hell of a lot cheaper than calling in a professional. Of course, with something like this there will be safety concerns, but keys aren't really the safest of security devices in and of themselves. Now, this certainly doesn't help the situation, but depending on how often you misplace your keys, the convenience could seriously outweigh the risk, as long as your careful about what you leave lying around.
