Why Commercial Door Security Matters

Business break-ins cost companies thousands in stolen inventory, damaged property, and lost productivity. But the right security measures can prevent most incidents before they happen.

The Stakes Are Higher for Businesses

  • Inventory and equipment worth thousands or millions
  • Sensitive data and customer information at risk
  • Employee safety during and after hours
  • Insurance requirements for coverage
  • Legal liability if security is inadequate

Types of Commercial Door Locks

1. Mortise Locks (Premium Choice)

The gold standard for commercial doors. Mortise locks are installed inside the door, making them extremely difficult to defeat.

Best for: Office buildings, storefronts, high-security areas

Grades: Look for ANSI/BHMA Grade 1 for maximum durability

2. Cylindrical Lever Locks

The most common commercial lock. Easy to operate with lever handles that comply with ADA requirements.

Best for: Interior doors, offices, restrooms

Considerations: Choose Grade 1 for exterior use

3. Panic Hardware (Exit Devices)

Code-required for public buildings. Allows emergency exit while preventing entry from outside.

Best for: Emergency exits, assembly areas, schools

4. Electronic Access Control

Modern solution providing keyless entry, access logs, and remote management.

Best for: Multi-tenant buildings, offices needing audit trails, 24-hour facilities

Master Key Systems Explained

A master key system allows different employees to have different access levels:

  • Grand Master: Opens everything (owner/CEO)
  • Master: Opens a department (manager)
  • Change Key: Opens specific doors only (employees)

Benefits:

  • One key for management instead of a heavy keyring
  • Easy to revoke access when employees leave
  • No need to change locks, just issue new keys
