A property manager carrying 30 individual keys for a 30-unit East Austin apartment complex has already lost control of their building. When one tenant loses a key, the manager cannot know how many copies exist. Master key systems solve this permanently. WOW Locks designs and installs precision-pinned master key hierarchies for Austin apartment complexes, office buildings, and multi-department campuses, giving managers single-key access while every tenant or employee key opens only their assigned space.

How We Save Your Day
The Hero Protocol
- Step 1
Call with door count and access requirements
Tell us your total door count, the number of key levels you need, and any restricted areas that require separate access. The dispatcher schedules a site survey and confirms a flat-rate quote range.
~10 min - Step 2
System design and flat-rate quote
WOW Locks designs the key hierarchy on paper, identifying which cylinders serve which level and specifying the restricted keyway if applicable. Written flat-rate quote provided before any work begins.
~60 min - Step 3
On-site installation
All cylinders are re-pinned on-site to the system specification. Master keys and change keys are cut, tested in every lock, and distributed by role.
120-240 min - Step 4
Documentation delivered
Key bitting records, system diagram, and key-holder assignments are documented and provided to the property owner or manager. Without this documentation, future expansion requires decoding.

What is a master key system?
A master key system uses precision-pinned cylinders with two shear lines. The change key (individual room key) aligns pins at the first shear line to open one specific lock. The master key aligns pins at a second shear line to open all locks in the system. Each cylinder is uniquely pinned so no change key can accidentally open another room. The math behind this is called key bitting space calculation, and getting it right requires professional system design. See our commercial locksmith hub for related services.
How do you prevent unauthorized key duplication?
Restricted keyways. Brands like Medeco, Mul-T-Lock, and Schlage PRIMUS use patented key profiles and sidebar mechanisms that require authorization from the manufacturer or the system owner to cut copies. Change keys in a restricted keyway cannot be duplicated at a hardware store or a big-box key kiosk. The system owner controls who gets copies. This is the difference between a functional master key system and one that degrades the moment a tenant walks into a Home Depot.
How long does installation take for a 10-unit building?
A 10-unit building with one master level and individual change keys typically takes 3 to 5 hours on-site, including system design finalization, cylinder re-pinning, key cutting, testing every combination, and documentation. We schedule installations at times that minimize disruption to tenants. A full-building installation in a larger complex may span two visits.
Which brands do you use for master key systems?
Medeco, Schlage, and Best (ASSA ABLOY) are our primary platforms for master key systems requiring key control. Kwikset and Schlage residential cylinders are used for simpler two-level systems where restricted duplication is not required. Brand recommendation depends on your building type, budget, and how important key control is to your access policy.
