The only thing worse than carrying a janitorial mess of keys is not being able to find them. The KeySmart Pro with Tile solves both problems. It holds up to 10 keys in two groups, tucked sleekly away until you need them. An integrated Tile Bluetooth tracker lets you locate your keys up to 100 feet away via an iPhone/Android app. You can also play a tone if they're not visible, and it works the the other way around too — the KeySmart Pro can ring your phone if you've misplaced it. Also included is a bottle opener, a loop for attaching a car remote, and an integrated LED flashlight. The USB-rechargeable battery will last a maximum of two to three months.
