How we use the wireless key finder:

1. Use a key ring or double-sided tape to connect the color-coded receiver to items that are often lost 

2. Press and release the corresponding color-coded button on the remote control 

3. If the receiver is in range, it will beep and the LED will flash 

4. If you don't hear a click, change your location or use a new battery and press the button again

5. Our item tracker can attach DIY mode stickers or handwritten stickers to the buttons on the corresponding letters on the transmitter. It is more convenient to remember lost items
