Description:<br />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 20 meters away!<br />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.<br />Features:<br />Usage: Personal<br />Model Number: card key finder<br />High quality<br />Remote key finder: 20 meters <br />Key finder: electronic key finder <br />Battery: CR2016 battery<br />Weight: 0.11kg <br />Packing: 1pc/blister card <br />Extended battery life: over 8 months with standard use<br />Specifications:<br />Electronic Key Finder / Wireless Key Finder. <br />Battery last time long / Long working distance. <br />RF wireless technology. <br />Environmental. <br />Stable function. <br />Find lost keys， just by a button. <br />Distance: 20m <br />1 x Transmitter <br />2 x Receiver <br />In original package (with English user manual on paperboard)<br /><img src="http://img6.eachbuyer.com/x15/p97/bc086_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p97/bc086_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p97/bc086_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p97/bc086_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p97/bc086_5.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p97/bc086_6.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p97/bc086_7.jpg" />
