Master Key Systems Fort Collins — Schlage Primus, Medeco M3 & Best Access Design

A properly designed master key system gives different users different access levels through a single hierarchy of cylinders. Done right, you rekey one cylinder when an employee leaves without touching the rest of the building. Done wrong, you end up rekeying 30 cylinders every time a key disappears. We've designed master key systems for HP-area tech companies, Old Town restaurants, downtown Fort Collins medical practices, and multi-tenant property managers across Larimer and Weld County since 2016.

Keyway brand comparison — what we install most

Schlage Primus (most common Fort Collins commercial): sidebar element on top of standard 6-pin cylinder creates a restricted keyway that hardware stores cannot duplicate. 10-year+ track record, holds up to bump-key and pick attacks, $85-$140 per cylinder installed. Right for most Fort Collins offices, retail, light industrial. Medeco M3 (medical / legal / financial / pharmacy): elevating-pin design plus restricted keyway, each key duplicate requires written authorization, $140-$220 per cylinder. Right for any environment where unauthorized key duplication is a compliance issue. Best Access IC core (schools, universities, large facilities): interchangeable core design — swap the core in 30 seconds without removing the lock. $110-$170 per cylinder initially, but rekey labor drops 70% over the building's lifetime. CSU campus housing uses Best for exactly this reason.

Designing a multi-tier master key system — our process

(1) Site walkthrough or blueprint review. We list every door, its user group, and exception requirements (ADA, fire-rated, after-hours-only). (2) Group doors into access categories. Most Fort Collins offices end up with 3-5 access groups: Public (front door, conference room, public restroom), Staff (back office, break room, supply closet), Management (HR, finance, server room), Owner (every door + safe). Each group becomes a 'change key' tier. (3) Design the master hierarchy. Master key sits at the top — opens every door. Below the master: sub-masters for departments or floors. Below those: individual change keys. A 20-door office might have 1 Master, 3 Sub-masters, 5 Change keys. (4) Pick keyway brand based on security and budget profile. (5) Order hardware (2-5 business day lead time for restricted keyways). (6) Install over 1-2 business days. (7) Hand off labeled keys, printed master schedule, encrypted records archived 7 years.

Retrofit vs new-build master key systems

Retrofit (existing building): We replace your existing cylinders with new master-keyed cylinders. Costs $400-$1,800 for typical 10-30 door offices. Takes 1-2 business days on-site. Recommended when you're changing tenants, after a security incident, or when current keys have proliferated beyond control. New-build (construction): We design the master system from the blueprint and order matched cylinders for the builder to install during finish-out. Costs $300-$1,200 depending on door count. We coordinate with general contractor on hardware schedule. Recommended for any new Fort Collins commercial build over 5 doors. ROI math for a 20-door office: WITHOUT a proper master system, expect $4,000-$7,000 over 10 years on ad-hoc rekeys and lock replacement triggered by every employee turnover. WITH a Schlage Primus master system, $1,800 upfront then $200-$400 per turnover for surgical rekeys. Break-even at 8-12 employee turnovers.

FAQ — Master Key Systems

Common Questions

How long does a master key install take?+
Design + quote: 48 hours after walkthrough. Hardware lead time: 2-5 business days for restricted keyways. On-site install for 10-30 doors: 1-2 business days. Total elapsed time: 1-2 weeks from initial call to fully installed.
Schlage Primus vs Medeco M3 vs Best Access — which should I pick?+
Schlage Primus for most Fort Collins offices (10-yr+ track record, reasonable cost, restricted keyway). Medeco M3 for medical/legal/financial/pharmacy (highest security, every key duplicate requires authorization). Best Access for schools, universities, high-rotation facilities (IC core makes future rekeys 70% cheaper).
Can you match an existing master key system?+
Yes — if the existing cylinders are a standard keyway (Schlage C, Kwikset KW1, etc.) we can rekey new cylinders to match. Restricted keyways (Primus, M3) require the original system's authorization documentation.
What happens when an employee leaves with their key?+
We rekey the cylinders that key accessed. With a properly designed master system, that's usually a 20-60 minute job — not a full building rekey. Records retention means we know exactly which cylinders to touch.
Do you provide ongoing maintenance?+
Yes — we maintain records of every master system we install. Can dispatch for adds, changes, and rekeys with same-day or next-day response.
What if our existing master system has no records?+
Common scenario — previous owner, lost paperwork, etc. We can audit the existing system, document the current hierarchy by examining each cylinder, and reconstruct a master schedule. $200-$500 for typical 10-30 door audit.
Can you install Schlage Primus in a residential setting?+
Yes — but it's uncommon. Primus is overkill for most homes; standard Schlage C keyways are sufficient. Primus makes sense for: high-value residential (Stone Creek, Promontory Greeley, TPC Colorado Berthoud), home offices with sensitive materials, or homeowners who've experienced break-in attempts.
What about access control / electronic master systems?+
We install electronic access control (keypads, proximity cards, biometric) and often combine with mechanical master keys (electronic on common areas, mechanical on individual offices). $300-$1,200 per door for electronic access depending on type.
