Suitable for wooden cabinets: The RFID card can penetrate relatively thick wood boards (up to 45 mm/1.7 inches). Key fobs are mainly used for replicating keys and are somewhat less convenient to use. This lock is suitable for doors with a thickness of 0 - 1 inch and is suitable for cabinets, lockers, wardrobes, file racks, and safes. 2. Compact size and robust structure: The bolt and lock body are made of metal, which is sturdy and durable. The cabinet door can be opened without touching. The RFID card/tag is easy to carry and store, providing security for personal belongings. It can enhance the safety of children at home and prevent them from randomly opening drawers or cabinet doors. 3. Low - battery alarm and automatic unlocking: After the lock is set and programmed, a long beep will sound to indicate low battery when opening. After the long beep sounds, the lock can still be used approximately 20 times. When the battery is too low to work properly, the door will automatically open. At this time, the battery must be replaced before the lock can be used again. 4. Two unlocking modes: - Single - card mode: Use one user card to unlock. - Double - card mode: Use two user cards together to unlock. 5. One card for multiple locks: This RFID lock is programmable. You can use one key (RFID card/key fob) to unlock multiple cabinet locks as needed. You just need to program the key into the lock and test it before installation. D.
