Review on Invisible DIY Electronic Cabinet Lock Kit with USB Cable - Hidden Lock Set for Wooden Cabinets, Drawers, Pantries, and Lockers - RFID Entry by Gabriel Rosenberg

Advance - "Instructions" does not work. He never says "dee-dee-dee" or "didi-didi-didi-didi-didi" so multiple keys can be used. Works with one key and that's it. If you lose the key, you're screwed and have to open the closet, ruining your furniture. If the batteries run out, you're done. You have to cut it out and thereby ruin your furniture. There are no installation steps. It says "use double-sided tape". That's all. Absolute JOKE! The screws that came with it are absolute rubbish. They undress very easily. If it doesn't work the first time, forget it. These screws are burnt out and cannot be reused. There is no template to help you align things. DO NOT BUY THIS. This is a garbage product.
