What Is a Master Key System?
A master key system is a setup where multiple locks are keyed differently, but one master key can open all of them.
Each lock can still have its own individual key (called a “change key”), but the master key works across every lock in the system.
Real-Life Home Uses in Phoenix
🔑 You have a main house and a guest house, and want to give guests limited access
🔑 You manage a rental unit or Airbnb on your property and need access to all doors
🔑 You want your kids to access only certain areas while you maintain full access
🔑 You’re caring for an elderly family member living in a separate entrance suite
🔑 You have a pool gate, garage, and back entry and want one key for everything
Benefits of a Master Key System at Home
✅ Simplifies your keyring — One key opens all doors you need
✅ Controls access — Give others only the keys they need
✅ Improves organization — Know exactly who has access to each space
✅ Works with existing locks — We can often rekey your current hardware into a master system
✅ More affordable than you think — You don’t have to buy new locks to set this up
What’s the Difference Between Master Keying and Rekeying?
- Rekeying changes the pins inside a lock to match a new key
- Master keying configures the lock so it works with two or more keys: a unique one and a master key
We can often rekey your existing locks and add a master key layer for improved convenience.
Is It Secure?
Yes—when set up professionally, a master key system is just as secure as individual locks. You still have full control over who gets each key, and we’ll document the key hierarchy for your peace of mind.
You can even combine a master key setup with smart locks or restricted keyways for added protection.
