We looked at five primary factors when considering which wireless key finder is the best choice.

Design: We considered the size and shape of each proximity sensor. We examined the ease of inserting a new battery into those devices with replaceable batteries. We also took note of indicator lights and other on-device controls.

Battery Life: We looked at how long the batteries powering the devices last, and whether or not you could replace them yourself. For key finders without replaceable batteries, we looked at whether the manufacturers offered a clearly defined upgrade program in which you could replace your device at reduced cost.

App Features: We evaluated the cross-platform compatibility of the companion apps. We also considered any additional features offered beyond just finding your keys, such as a two-way finding feature that let you locate your phone using the key finder.

Volume: We compared how each alarm sounded by testing each device outdoors and placing each key finder in a laundry basket full of clothes.

Range: We tested not only how far we could walk away from a proximity sensor before it lost its connection, but also how easily that connection could be regained once we were back in range.
