Sonic Key Finder

The Sonic Key Finder Key Chain ends hours of hopelessly searching for your keys. All you need to do is whistle or shout. Any loud noise causes the Key Finder Key Chain to beep and the light to flash. Also handy for finding keyholes.

The key finder will beep around any very loud noise. If you are near a loud TV or loud noises, it will obviously go off. Please make sure your environment is fairly quiet or the sonic key finder will go off whenever it senses a loud or high pitch noise.
