That early-morning scramble to find your keys before you leave the house doesn't have to be so frantic if you've got a wireless key finder handy. No bigger than a standard key chain — and even smaller, in some cases — these dongles connect to your smartphone via Bluetooth LE to alert you when your keys are nearby or in danger of being left behind.

Plenty of key finders promise to keep your valuables close at hand, but after putting a variety of devices through their paces, the second-generation Tile ($25) emerged as the best choice for tracking the whereabouts of your keys, with improved range and a helpful two-way finding feature that lets you locate your phone from your key chain. Our runner-up was the Duet by Protag($29), which packs its feature set into a compact design. If you need a device with a loud alarm, check out the TrackR Bravo ($29), while the Pebblebee Honey ($24) adds other features like the ability to control your smartphone's camera.

  • I am surprised there is mention of the Cube. That is the brand that I hear so much about. How does it stack up with the other key tracker devices. Was it in the test and just didn't rate?
  • This device was not that good. The tile and phone could be right next to each other and not work. It kept losing it's bluetooth connection. Went ahead and returned the tile, if no bluetooth connection, it is useless for finding anything.
  • I'm looking for a key finder now, and this is the best, most current article I could find. It's a very well-written, in-depth, and comprehensive article. Great work! That said, I agree that the omission of a review of Lapa is a mistake. Would you please add them to your research?

    (I also looked into Pixie, but I don't think there's a need to review them in this article.)
