Cam Lock vs Combination Lock: Which Is Better for Schools & Workplaces? (UK Guide 2026)

Choosing between cam locks and combination locker locks affects long-term maintenance costs, user experience and site security. In UK schools and workplaces, both options are widely used, but each suits different operational needs.

This guide compares cam locks and mechanical combination locks to help facilities managers select the right system.

What Is a Cam Lock?

A cam lock is a traditional keyed locker lock. It uses a mechanical cylinder operated by a physical key.

• Low upfront cost
• Simple installation
• Replacement keys available by code
• Supports master key systems

What Is a Mechanical Combination Lock?

A mechanical combination lock operates using a numeric code rather than a key. It eliminates physical key management.

• No keys required
• Public or private use modes
• Higher upfront cost
• Reduced long-term key replacement

Cost Comparison

• Cam Locks: Lower initial cost but ongoing key replacement expenses.
• Combination Locks: Higher purchase cost but reduced administrative burden.

Security Considerations

• Cam locks rely on key control.
• Combination locks rely on secure code management.
• Master key systems may simplify cam lock oversight.
• Reset key control is critical for combination locks.

Which Is Better for Schools?

Schools with high key loss rates often benefit from combination locks. However, smaller schools with effective key registers may find cam locks more economical.

Which Is Better for Workplaces?

Workplaces with stable staff numbers may prefer cam locks. High-turnover or shared-use environments often benefit from combination systems.

When to Upgrade

• Frequent lost key incidents
• High administrative overhead
• Refurbishment projects
• Desire to modernise facilities
