Keylink attaches to keyring, makes noise via app, button makes phone ring Motorola has revealed an accessory which could help prevent people from losing their keys or their phone. The Motorola Keylink is designed to be attached to a key ring, and can be set to make a noise from a connected smartphone at a range of up to 100 feet if they are misplaced, with a button on the key fob able to trigger the smartphone's ringer as well. While similar in concept to the Nokia Treasure Tag, Motorola's effort also adds in the ability to unlock a smartphone by being within a certain range. The second-generation Moto X, Droid Turbo, or any phone running Android Lollipop can alter the Trusted Device settings on their smartphone to keep the device unlocked while the Keylink is within range, re-enabling any passcode or other security if the two items are separated. The Motorola Connect companion app for triggering the ringing function is available for both Android and iOS devices, with Motorola also making the Keylink able to withstand a little rain with its waterproofing. Battery life is said to be up to one year, as it uses a replaceable coin cell battery. Shipping now, the Motorola Keylink is available from the manufacturer directly or T-Mobile, priced at $25.
