Panasonic's wireless technology makes it possible to detect up to 200 meters away from the handset.

*This range may be shorter when the Key Locator / Key Detector is near concrete barriers, etc

Both the handset and the Key Locator / Key Detector beep sound when being searched.
The handset LCD display tells you how far away the misplaced item is.

Rated 5 out of 5 by Key finder Works great!! I'm happy that I bought it. Now I can find my keys when I miss place them within my home. I am surprise how strong the signal is. Did not think it would work when my keys were in a closet but it did. A good price as well as I bought 2 of them. 1 for both of us. August 5, 2016
Rated 4 out of 5 by Tone too high pitched Perhaps a major group who needs this item is older Americans--seniors. Yet those of us with some hearing loss find the alert tone so high pitched, we can't hear it unless we're standing on top of it. Not very good, that. Would benefit from a tone with a lower pitch. Set up and function seemed fairly easy to do, so that's a plus. February 22, 2016
Rated 4 out of 5 by Better than nothing. The beep isn't very loud but it's better than nothing. February 18, 2016
Rated 4 out of 5 by works okay, wish it was cheaper I purchased one for my wife's keys when I purchased new phones. I'm not sure why they are so expensive, as I would have gotten several if they were not. It is not too big, which I was afraid it might be from the picture. Like others have reported, it is not very loud, and does not even begin to beep until you are within a few feet of it. The phone handset does a decent job in getting you to the approximate area of where it is, and when you are about 3-6 feet away, the detector begins to beep, which you wouldn't be able to hear from farther than 6 feet away. I would buy more if they were cheaper. January 5, 2016
Rated 2 out of 5 by Not as useful as I expected The sound on the fob is very low. The handset sometimes increases beeps even when you're not getting close to the fob. The fob beeps of its own accord sometimes when it's hit or moved - this has nothing to do with trying to find it. October 12, 2015
Rated 2 out of 5 by Sound level too low, recommend increase in sound level October 7, 2015
Rated 3 out of 5 by Should be a big help. I have only used the key finder in "test" situations, not a real loss, but it seems to work well and be easy to use. If I should lose my key within the house, it would definitely find it for me. October 3, 2015
Rated 5 out of 5 by Brilliant invention Thank you a million times to whoever invented this wonderful device, it has found my son's keys multiple times already. September 9, 2015
