About this item
- [Scope of Application] The 13.56MHz RFID card can penetrate thicker wood boards (up to 38mm/1.5 inch). It is suitable for 1.2inch thick wooden doors, ideal for cabinets, drawers, lockers, cupboards, closets, data racks, safes, etc.
- [Safe and Sturdy] The latches and mortises are made of metal, which is sturdy enough for privacy and security. It has compact size and sturdy mechanism, providing security protection for your personal belongings. It can improve children's safety at home and prevent children from opening drawers or cupboards at will.
- [Low Battery Alarm] No need to worry about being locked out. After the lock is opened, it will make a long beep sound as needed to indicate the low battery status, and it can be used about 15 times after that. When battery becomes too weak to operate, the door will automatically open, and you must replace battery at this point before use lock again.
- [Battery Operated] This DIY kit needs no drilling, which is easy to fix with screws. The toolkit includes installation templates. It is powered by 4 AAA alkaline batteries, which can last for 9 months with normal use. If you prefer, you can also use a USB power adapter instead of the alkaline batteries.
- [Programmable RFID Lock] This RFID lock is programmable, which is easy to reset, add, remove your own key card. You can use one key to open several cabinet locks. The only thing you need to do is just program the key and test it before installation.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
