Should I buy mechanical safe deposit box or self-service safe deposit lockers?

Updated: Apr 12

When choosing safe deposit lockers, it's important to consider factors such as the type of customers you serve, the level of security required, and the space available for installation. Here's a breakdown of the types of safe deposit boxes and their respective advantages and disadvantages to help you make an informed decision:

Mechanical Safe Deposit Box:


  1. Low Product Failure Rate: Mechanical safe deposit boxes have a low failure rate and typically require minimal maintenance.

  2. Customer Autonomy: Customers can deposit and withdraw items independently, enhancing security and providing peace of mind.

  3. Flexible Location: These boxes can be placed in relatively hidden areas such as garages or the first floor, reducing rental costs.

  4. High-Quality Service: With employees available to assist throughout the process, these boxes offer friendly and personalized service, particularly suitable for elderly customers.

  5. Customization: Large and super-large cabinets can be customized to accommodate valuable items such as gold, antiques, and cultural relics.


  1. Space Requirements: Mechanical safe deposit boxes require a larger space, including areas such as the treasury, business area, office, and rest zones (typically 50-1000 square meters).

  2. Personnel Costs: Multiple service personnel may be required, increasing operational expenses.

  3. Fixed Business Hours: Customers can only access the safe deposit boxes during specific hours, limiting flexibility.

Self-Service Safe Deposit Box:


  1. Space Efficiency: Self-service safe deposit boxes require less space, typically comprising only the account opening counter, vault, and operation room (10-30 square meters).

  2. 24/7 Service: These boxes can offer round-the-clock service, appealing to customers who require flexibility in accessing their belongings.

  3. Lower Personnel Costs: With no need for multiple service personnel, operational expenses are reduced.


  1. Maintenance Needs: Self-service boxes involve electronic devices that require regular maintenance, with a relatively higher failure rate.

  2. Customer Interface: The self-service process may not be as friendly to elderly customers who prefer assistance.

  3. Location Requirements: These boxes are typically installed in crowded areas such as shopping malls or urban centers, leading to higher rental costs.

  4. Limited Size: Self-service boxes usually offer only small to medium-sized compartments, restricting the storage of large or heavy items.

Choosing the Right Type:

  • Mid-to-High-End Customers: For customers with higher storage requirements for valuables and greater demands for safety and service, fixed mechanical safe deposit boxes are preferable.

  • General Public or Mid-End Customers: Self-service safe deposit boxes are suitable for customers mainly storing documents, jewelry, and personal items, especially if flexibility in use time is important.

Consider your target customer base, space constraints, and service preferences when selecting the type of safe deposit box for your business.
