This is the smart keyholder that uses advanced locator technology so your keys are never lost. It works with the free Tile phone app to help you find your misplaced keys within a 150' range. If the keyholder is nearby, the app uses a Bluetooth connection to ring the keyholder. If you misplaced the keys elsewhere, you can see the keyholder’s location on a map. The smart technology also works in reverse: if you have the keyholder but can’t find your phone, press a button to make the phone ring, even if it’s in silent mode. The compact keyholder holds and organizes up to 14 keys, and has a built-in LED flashlight, bottle opener, and flathead screwdriver. Charges via USB. 4" L x 3/4" W x 3/4" D. (1 oz.)
