3S Smart key dock

The smart key dock supports the collection of lock IDs. When a key is inserted back into the host, it automatically uploads data and charges the key, with red and blue light indicators. It can manage no less than 5 keys simultaneously, and the status of each key can be monitored in the system. Unauthorized electronic keys cannot be removed from the host, while authorized keys will automatically pop out. After being reinserted, keys are automatically returned and registered.
