Frequently Asked Questions (FAQs)

  • What is a master key system, and how does it work?

    A master key system allows different keys to open specific locks, while a master key opens all of them. For example, tenants may each have a unique key to their apartment, but a property manager can access all with one key. This structure simplifies key management without compromising individual security.

  • Can a master key system be used in residential homes?

    Yes, a master key lock system can be installed in residential properties, especially in large homes with multiple access points, guest suites, or rental units. It's a great way to maintain control while offering limited access to family members, guests, or maintenance staff.

  • Is it safe to use a master key system?

    Absolutely. When installed by a professional master key system locksmith, the system is highly secure. Access levels are clearly defined, and the locks are designed to resist tampering and unauthorized duplication.

  • Can I rekey my existing locks into a master key system?

    In many cases, yes. Existing hardware can often be adapted to fit into a lock with a master key system, provided it’s compatible with the new pinning system. Our technicians can inspect your locks and recommend the best approach for retrofitting or replacing.

  • How often should a master key system be maintained?

    We recommend having your master key door lock system inspected and serviced annually or after major tenant or staff changes. Regular maintenance ensures the system continues working smoothly and remains secure.
