What properties use master key systems?

Apartment buildings, office complexes, hotels, schools, hospitals, warehouses, churches, HOA common areas—any property with multiple doors and different access levels. Even large homes with guest houses, workshops, or pool houses benefit from simplified key management.

Can you expand my existing master key system?

Usually yes, if the original system was designed well. We assess your current setup, determine available expansion capacity, and advise on what's possible. Poorly designed systems may be maxed out—we'll tell you honestly.

What if someone copies a master key?

With standard keyways, that's a real risk. We recommend restricted keyways that can ONLY be duplicated by authorized dealers with your key control card. No hardware store copies, no unauthorized duplicates. This costs slightly more but provides actual key control.

How long does master key system installation take?

It depends on size. A small office might be done in a day. A 100-unit apartment building might take a week. We schedule around your operations and provide realistic timelines upfront.

Master keys vs. electronic access—which is better?

Both have their place. Electronic access offers detailed tracking and instant revocation but requires power and networking infrastructure. Master key systems are simpler, more practical, and work during power outages. Many properties use both: electronic for high-traffic entrances, master keys for utility/storage areas.

Signs You Need Master Keys

key

Your Keyring Weighs More Than Your Phone

Carrying dozens of nearly-identical keys, fumbling to find the right one at every door. A master key means ONE key in your pocket opens every door on your property.

Maintenance Needs Access to Everything, But...

...tenants should only access their units, managers need their floors, and the janitorial crew needs the common areas. That's hierarchical access—everyone gets exactly what they need.

Tenant Turnover Is a Constant Headache

Every move-out means rekeying. With a proper master key system, you rekey just that unit without affecting anything else. Your master still works. Their old key doesn't.

You Don't Know Who Has Keys Anymore

Past employees, old contractors, tenants from three years ago—keys are everywhere. Master systems with proper key control let you know exactly who has what.

Your Current System Is Maxed Out

You're adding units or doors but your locksmith says the existing system can't expand. Poorly designed systems hit limits. We design systems with growth in mind.

Our Process

How We Design Your System

1

Map Your Access Needs

We sit down with you to understand your property: who needs access to what, how many levels of hierarchy, future expansion plans.

2

Design Your System

We create a key hierarchy that makes sense—not overengineered, not undersized. Clear documentation of what key opens what.

3

Assess Existing Locks

What can be rekeyed into the new system? What needs replacement? We give you options, not just the expensive answer.

4

Implementation

We rekey or install locks, cut your key hierarchy, and configure restricted keyways. Minimal disruption to operations.

5

Documentation and Training

You receive complete records: what keys exist, who has them, what they open. We train your team on adding/revoking access.

What's the difference between key cards and fob access?

expand_more

Both use RFID technology. Key cards are credit-card sized and often more practical. Fobs are keychain-sized and more convenient. Both can be instantly deactivated when an employee leaves. We install and program both types.
