Lock Change Service — When & Why Highlands Ranch Homeowners Replace

Lock change means full hardware replacement: out with the old cylinder, deadbolt, lever, or strike; in with new. It is the right move in some scenarios and overkill in others. Most of the time, rekeying is the better answer (see our rekey vs replace decision guide). But when lock change is the right call, here is what to expect.

Five Scenarios Where Lock Change Beats Rekey

  1. Locks are 15+ years old. Pin springs and tolerances wear out past 15 years. A perfect rekey on tired hardware fails within 12 months.
  2. Hardware is physically damaged. Cracked deadbolt housing from a forced entry. Stripped lever set. Corroded cylinder. Cosmetic dings on a high-traffic door.
  3. Security grade upgrade. Going from ANSI Grade 3 (builder-grade Kwikset Smartkey) to Grade 1 (Schlage B60) requires new hardware, not pin replacement.
  4. Aesthetic upgrade. You bought the house with builder-default polished brass and want oil-rubbed bronze across all entry doors. New hardware, not rekey.
  5. Smart-lock retrofit. Smart locks (Yale Assure, Schlage Encode, August, Kwikset Halo) require replacing the existing deadbolt mechanism. Rekey cannot give you keypad entry.

What Lock Change Costs in Highlands Ranch

ScopeCost (installed)
Single deadbolt, builder-grade Kwikset$95–$135
Single deadbolt, Schlage B60 ANSI Grade 1$185–$245
Single deadbolt, Medeco / Mul-T-Lock high-security$325–$425
Single smart lock (Yale / Schlage Encode / August)$245–$385
Whole-home (4–6 doors, Schlage B60)$685–$1,285
Whole-home smart-lock retrofit (3 doors)$685–$985

Process & Time On-Site

Single deadbolt change: 25–40 minutes. Single smart-lock retrofit: 40–75 minutes (door-prep + WiFi pairing + multi-user code setup). Whole-home replacement: 2–4 hours typically. We supply hardware on the truck for Schlage and Kwikset; restricted-keyway hardware (Medeco, Mul-T-Lock, ASSA) requires a 2–4 day pre-order.

Should You Buy Hardware Yourself?

You can. Big-box stores carry Schlage and Kwikset at retail ($60–$185 per deadbolt). We charge $85 labor only if you supply hardware. Trade-off: you pick the brand and finish; we cannot warranty hardware we did not source. Most clients prefer we supply — cost is similar after labor and we warranty parts plus labor for 1 year.

★★★★★

We installed Yale Assure smart locks on three doors in our DTC office building. The team coordinated with our IT for the Wi-Fi mesh and access control integration, and trained our front desk staff on the management app. Whole project completed in one afternoon.

— Tom B., Greenwood Village, CO
★★★★★

I run a small office downtown and our Adams Rite storefront deadbolt was failing — wouldn't throw fully. They diagnosed it as a worn cylinder rather than total replacement and rebuilt it for $185 instead of the $580 quote I had from another company. Honest and competent.

— Linda H., Englewood, CO
★★★★★

Snapped my key off in the front door at 6am leaving for work. They walked me through staying calm on the phone, got out within 30 minutes, extracted the broken half cleanly, and cut a fresh key on site. No damage to the cylinder. Saved me from a $300 lock replacement.
