What is the difference between shared and assigned locker locks?

Shared locker locks are suitable for scenarios with rapid user turnover where identity cannot be pre-registered, such as one-time gym visitors, swimming pool guests, temporary lockers for students changing for PE classes, or shift-based employee storage in retail stores. These locks are characterized by "not binding identity, only binding the current use." Common practices include users setting a 3- to 4-digit password themselves, with the next user resetting it after use, or using coin-operated mechanical locks with a personal padlock. For buyers, the key evaluation points for shared locks are: whether the reset mechanism is intuitive enough (so non-technical users can operate it), whether the mechanical structure can withstand frequent opening and closing (potentially dozens of times per day), and whether an administrator key is needed for emergency opening. Before purchasing, it is recommended to physically test the reset process once to confirm it can be done without tools; otherwise, there will be a large number of "forgot to reset" complaints on site. Jintai Industrial's password lock and key lock product lines can address such applications, supporting OEM customization and brand collaboration. Actual specifications and reset methods are confirmed based on the project.

Access rights for assigned locker locks are uniformly issued by the management party, commonly seen in long-term employee lockers, monthly membership fitness lockers, fixed school classes or dormitory beds, and rental storage lockers. The core requirement for this type of lock is "traceable, reclaimable, and changeable." Therefore, while mechanical key locks have the lowest initial cost, once a key is lost, the lock or the entire lock cylinder must be replaced, leading to high subsequent maintenance costs. Electronic password locks allow administrators to reset passwords without touching the hardware when a password is lost. Higher-end IoT smart locks can issue and revoke access via Bluetooth, NFC, RFID, or a cloud backend, allowing remote deactivation when a single user leaves without needing to visit the site to change the lock. For buyers, the evaluation focus for assigned locks is: whether access changes require on-site operation at each locker, whether batch processing is possible (e.g., revoking access for an entire floor of students graduating at once), and whether access records are traceable (who opened which locker and when). Before purchasing, it is recommended to first estimate "how many access changes are expected within a year," as this number will directly determine whether to choose mechanical, electronic password, or IoT-connected solutions.

Choosing between a mechanical lock, an electronic lock, or an IoT-connected lock depends on where the management responsibility lies and how frequently changes are made. Mechanical locks (including key locks and mechanical combination locks) have the lowest cost, require no power, and have a low failure rate, but a lost key or forgotten code means destructive opening, after which the lock or lock core must be replaced. They are suitable for scenarios with fixed users and very infrequent changes, such as long-term employee lockers in a small office with a stable headcount. Electronic combination locks can be reset by an administrator and sit between mechanical locks and IoT locks, making them suitable for medium-sized sites such as school class lockers or monthly-rental student lockers, where permission changes occur about once a quarter. IoT-connected locks (Bluetooth, NFC, RFID, cloud back-end) have the highest cost but allow batch issuance and revocation of permissions and leave open/close records, making them suitable for sites with high personnel turnover, such as chain gyms, multi-branch schools, and co-working spaces. For buyers, the key to selection is not that newer technology is always better, but whether the management process can support the technology. If there is no dedicated staff to operate the back-end, permission changes on IoT locks can become a bottleneck, making an electronic combination lock a more practical choice. Before purchasing, it is recommended to first assess the management manpower available, then decide on the technology level.

The cost differences between shared-use and assigned-use locks mainly lie at two levels: the price per lock and the overall lifecycle management cost. You cannot look only at the per-unit quote. In terms of per-lock price, mechanical shared-use locks are the lowest, electronic combination locks are in the middle, and IoT-connected locks are the highest, but the gap narrows with purchase volume and degree of customization. In terms of overall lifecycle cost, shared-use locks have almost no lock replacement cost because users are not fixed, but the mechanical structure may wear out earlier due to frequent opening and closing, so the replacement rate must be considered. Assigned-use locks have a higher unit price, but if the right technology level is chosen, subsequent permission changes can be handled by the administrator without calling a locksmith or replacing the entire lock core each time, which saves money in the long run. For buyers, the correct way to compare costs is to estimate the number of permission changes per year, multiply it by the cost per change, add that to the initial purchase cost, and divide by the estimated service life of the lock to arrive at the annual cost of ownership. This figure often overturns conclusions based on per-unit quotes alone. For example, in a site with high employee turnover, the annual cost of ownership for IoT locks can actually be lower than for mechanical locks. Before purchasing, it is recommended to ask the supplier for an annual cost of ownership comparison sheet for different options, and then make a decision based on that.

The OEM/ODM process from inquiry to mass production typically consists of five stages: DFM design review, mold development, prototyping and validation, testing and certification, and mass production. Each stage has decision points that buyers must participate in. During the DFM design review stage, buyers need to provide information such as cabinet dimensions, cutout specifications, user operation flow, and estimated annual usage. Based on this, the supplier evaluates whether existing molds can be reused or new molds are required. The decision at this stage directly affects subsequent mold costs and unit prices. In the mold development stage, buyers need to confirm the mold material, estimated lifespan (usually calculated by the number of mold cycles or annual output), and mold ownership. In the prototyping and validation stage, buyers need to actually test the sample's operating feel, opening and closing smoothness, and whether the password setting process matches the end user's capabilities. In the testing and certification stage, applicable regulations and certification items need to be confirmed based on the target market, but specific certification numbers and test data must be issued by certification bodies after actual submission, and cannot be verbally claimed by the supplier. In the mass production stage, buyers need to confirm delivery time, acceptance criteria, packaging methods, and the yield guarantee for the first production batch. Jintai Industrial's OEM/ODM process covers all five stages mentioned above. The actual timeline and costs are confirmed based on specifications and project complexity. It is recommended that buyers provide estimated annual usage and target market when requesting a quote, so the supplier can evaluate the most suitable configuration.
