Master Key Systems

One key for the owner, the right doors for everyone else, and no more hand-stamping copies for every new hire.

A master key system is a commercial keying setup where one master key opens every lock in a building, while each individual key opens only its assigned door. Apex Locksmith Pros designs and cuts the keying hierarchy, re-pins your existing locks, and hands you a key schedule so you control exactly who gets into what across your office, retail space, or property.

Simple & fast

How Master Key Systems Work

We map your access needs, design the keying hierarchy, then re-pin your locks so one master opens everything and each key opens only its door.

  1. 1

    On-site walkthrough

    A tech comes to you, counts your doors, checks your existing hardware, and asks who needs access to which areas. This is where we catch problem doors before they cost you.

  2. 2

    Design the key hierarchy

    We build a keying schematic with your master, sub-masters for departments or floors, and individual change keys. You approve who opens what before we cut a single pin.

  3. 3

    Re-pin and hand off

    We re-pin or swap your cylinders on site, test every door, then give you labeled keys and a written key schedule for your records.

  4. 4

    Pay the assessed price

    You pay the per-building number set after the walkthrough. Down the road, a departing keyholder means re-pinning a few doors, not redoing the system.

Frequently Asked Questions

Re-keying changes one lock so old keys stop working; master keying adds a second key combination to each cylinder so a single master opens many doors while each door still has its own key. Master keying is the layered version built across a whole building.

Usually yes. Most pin-tumbler commercial cylinders from Schlage, Kwikset, Medeco, and Best can be re-pinned to a master system, so you rarely need to buy all-new hardware.

No. We re-pin your existing cylinders on site wherever the hardware supports it, and only recommend new locks for doors with worn or incompatible cylinders.

We can build the system on restricted or patented keyways like Medeco or Mul-T-Lock, where blanks aren't sold at hardware stores and copies require your authorization. That keeps your master key from being duplicated behind your back.

Yes. With a master system we can re-pin only the affected doors and issue new change keys, so you keep your master working without re-keying the entire building.
