Radio Frequency Receiver Electronic Key Finder

Features
An extra sensitive radio frequency (RF) receiver will help you find your keys – behind walls, inside drawers, in the lounge, under bedding and any other hard to find places, up to 40 meters away!
Simply attach the RF receiver key ring to your keys. To locate, press the switch on the credit card sized RF transmitter which will then emit a special inaudible RF signal. The receiver will reply with a multi toned sound which will continue until you locate your keys and press the stop button on the receiver. The credit card sized transmitter will fit neatly in your purse or wallet so it’s always there when you need it.
