Use radio frequency to find your lost keys and more! Simply press the button on the transmitter that corresponds to the color receiver you're looking for to trigger a beep from that receiver. The beep is loud enough to hear even when your lost item is in another room or buried in your sofa. It will sound for 10 seconds each time you push the transmitter and can operate when the transmitter and receiver are up to 145 feet apart!
