Ulisem Waterproof Mechanical Combination Lock: Security and Simplicity for Your Door. Discover the Ulisem mechanical combination lock, a robust and reliable locking solution designed to simplify your daily life while enhancing the security of your access points. Made of high-quality zinc alloy, this lock offers exceptional durability and increased weather resistance, making it perfectly suited for both indoor and outdoor use. No more lost or forgotten keys: opt for a convenient system where access is granted via a personalized password. Why choose this keyless lock? This model is ideal for various situations where using traditional keys is impractical or cumbersome. It is perfectly suited for office doors, interior doors in your home, guest rooms, vacation rentals, or even common areas. Thanks to its waterproof design, it effectively resists humidity and climatic variations, guaranteeing smooth operation year after year. Customizable and Secure Code: One of the major advantages of this mechanical lock is its flexibility. You can set a password of 1 to 11 digits. For the best balance between security and memorability, it is recommended to choose a code between 4 and 6 digits. A clever feature of this system is that the order of the digits is not strictly sequential when entered. For example, if you program the code 123456, the lock can be opened even if the digits are entered in a different order, such as 231456, as long as all the digits of the code are present. This facilitates quick opening while maintaining a high level of security against prying eyes. Detailed Technical Specifications: Material: Solid and durable zinc alloy.
