I love key trackers because they help me keep track of my keys and other essentials, as long as my phone hasn’t been lost or out of reach. The best key trackers take this a step further and use massive locator networks to help you locate your lost tracker even if you’re miles away.

My favorite is the Tile Pro (2022). It has excellent range for local use and uses Tile’s vast network when you’re out of Bluetooth range.

TL;DR: This key tracker justifies its high price with excellent range and an exceptionally loud alarm.

The Tile Pro has a long Bluetooth range, an extremely loud alarm, a high IP rating, and uses Tile's massive locator network. For that reason, it's my top recommendation for the best key finder.
