Frequently Asked Questions
What is a master key system?
A master key system allows one key (the master) to open multiple locks, while individual keys only open specific locks. It’s a tiered access control solution ideal for multi-unit properties or businesses.
Is a master key system secure?
Yes. When set up by a professional, master key systems offer excellent security. We use high-security, restricted keyways to prevent unauthorized duplication.
How long does it take to set up?
Simple setups can be done in a day. Larger properties may take 2–3 visits depending on the number of locks and access levels required.
Can I add more locks later?
Absolutely. We design systems to be expandable so you can add locks to the system at any time without replacing the entire setup.
