Shanghai Kuntu Industrial Co., Ltd.’s “lock for key box” series is a specialized line of locking mechanisms designed exclusively to secure our range of key boxes—ensuring that the keys stored inside remain protected from theft, unauthorized access, or tampering. Unlike generic locks, our lock for key box is engineered to fit seamlessly with our key box designs (both portable and wall-mounted), featuring a compact size, durable construction, and security features tailored to key storage needs. Backed by over 20 years of manufacturing experience and BSCI-certified quality control, these locks are a critical component of our key storage solutions, trusted by homeowners, businesses, and property managers worldwide. The design of our lock for key box prioritizes compatibility, security, and ease of use. We offer two primary lock types to suit different key box models and user preferences: - Key-operated locks: Crafted from brass with a high-security pin tumbler design (resisting picking), these locks are ideal for users who prefer the reliability of physical keys. Each lock comes with two keys (one primary, one spare) and is designed to fit the small lock hole of our portable and wall-mounted key boxes—no extra drilling or modification required. - Combination locks: Featuring a 3-digit resettable code (1,000 possible combinations), these locks eliminate the need for keys—perfect for users who share key box access (e.g., family members, co-workers) or frequently misplace keys. The combination dial is large and easy to read, with a tactile grip for use with gloves or in low-light conditions. For outdoor key boxes, both lock types include a weatherproof seal (preventing rain, dust, or rust from affecting the mechanism) and a UV-resistant finish (fading resistance in direct sunlight). A notable case involves a property management company in the United States that uses our wall-mounted key boxes (equipped with combination locks) to store keys for rental properties. The company’s managers can set a unique combination for each key box (linked to the property address) and share the code with maintenance workers or tenants—eliminating the need to distribute physical keys. After 2 years of use, the company reported zero incidents of unauthorized access, and the combination locks showed no signs of wear (even with daily use by multiple workers). The property manager also praised the lock’s weatherproof design: key boxes mounted outside survived heavy rain and snow without lock jamming. For homeowners, our key-operated lock for key box is a popular choice for portable key boxes—providing peace of mind that keys will remain secure if the box is lost or stolen. A homeowner in Canada uses our portable key box (with a key lock) to store car keys and house keys while camping, noting that the lock is easy to open with one hand (even with gloves) and that the brass construction has resisted rust despite exposure to lake water and humidity. For small businesses, such as retail stores or offices, we offer our combination locks for wall-mounted key boxes—allowing employees to access store keys or office keys without carrying a physical key. A boutique in France uses our key box with a combination lock to store cash register keys and stock room keys, and the store owner noted that the combination is easy to change if an employee leaves the company (a simpler process than rekeying a traditional lock). Our commitment to cross-cultural adaptability ensures our lock for key box meets regional needs. For example, in countries like Japan, where users often prefer compact designs, we offer smaller key heads for our key-operated locks (fitting easily in small key cases). In North America and Europe, where combination locks are popular for shared access, we provide larger dials for easier reading. Our foreign trade team also works with clients to integrate our locks with their existing security systems—for instance, linking combination lock codes to employee ID numbers for access tracking in large organizations. Every lock for key box undergoes rigorous testing at our Shanghai factory, including: - Compatibility tests: Each lock is tested with its corresponding key box model to ensure a seamless fit and smooth operation. - Security tests: Key-operated locks are tested against common picking tools; combination locks are tested for code retention (ensuring the code does not reset accidentally). - Durability tests: Locks are cycled 1,000 times (opened and closed) to verify wear resistance. We also offer lock replacement services (for damaged locks) and key duplication (only for authorized clients with proof of purchase). If you use our key boxes and need information on lock options, replacement parts, or bulk lock orders, please contact our team. We are dedicated to ensuring that your key box locks provide the same level of security and reliability as our key boxes.
