How a Residential Master Key System Works
A master key system is a pin-tumbler hierarchy that lets a single master key for all locks open every door while each individual lock still works with its own unique key. You keep day-to-day convenience, and guests, cleaners, or tenants keep their privacy.
- Individual keys operate just one door—bedrooms, home office, side gate.
- Section keys (optional) work a group of locks, e.g., all upstairs rooms.
- Master key opens every lock on the property, including exterior doors and Master Lock padlocks on sheds or gates.
Why Homeowners Love Master Keys
Quickly change a master lock combination or revoke a lost sub-key without swapping hardware.
Carry one key instead of five.
Expand the hierarchy when you add a guest house, ADU, or new garage.
Give contractors a sub-key that won’t open bedrooms or the office.
