The Problem With Multiple Keys
If you manage an office, retail space, or apartment complex, you know the frustration: different keys for every door, staff carrying oversized keyrings, constant rekeying when employees leave, and no clear way to control who can access what. A master key system solves all of these problems simultaneously — and costs far less than most business owners expect.
What Is a Master Key System?
A hierarchical lock configuration where individual keys open only specific locks, while master keys open groups — and grand master keys open everything. The same lock opens with both a specific employee key and a manager's master key through "cross-keying" engineered into the same pin stack.
Simple office example:
- Employee key: Opens only their office and main entrance
- Manager key: Opens all offices in their department plus common areas
- Grand master key: Opens everything in the building
Each person carries one key. When an employee leaves, you rekey their specific lock — not the whole building.
Who Needs a Master Key System?
- Office buildings with multiple tenants or departments
- Apartment complexes — maintenance access with tenant privacy
- Hotels and hospitality properties
- Medical offices with privacy requirements
- Warehouses with different access zones
What Does It Cost in Las Vegas?
- Small office (5–10 doors): $300–$600
- Medium facility (15–30 doors): $600–$1,500
- Large complex (50+ doors): $2,000–$5,000+
Includes security survey, key schedule design, rekeying or cylinder replacement, and all keys. Long-term savings in management and rekeying typically justify the investment within the first year.
