When's the Best Time to Rekey or Upgrade Locks in Colorado?
Seasonal · Published 2026-01-21
Lock service can happen any month, but Highlands Ranch homeowners get noticeably better outcomes when they schedule with Colorado's climate in mind. Avoid winter for outdoor work; favor October and April for preventive service. Here's the year's schedule we recommend.
October — The Sweet Spot
By far the best month to schedule rekey, lock change, deadbolt installation, smart lock retrofit, or annual lock service in Highlands Ranch. Reasons:
- Daytime temperatures still mild (45-65°F), no winter freeze risk during install
- Locks have endured the summer heat (95°F max) and any expansion/contraction has settled
- Pre-winter is when chronic problems surface — sticky locks, worn cylinders, smart-lock battery drain — ideal for diagnosis
- Locksmith schedules are open (not the post-burglary December rush)
- Holiday gift-giving season (smart locks make great gifts) hasn't spiked demand yet
April — Second-Best
Spring service is good for catching issues that emerged over winter. Door alignment shifts during freeze cycles, smart-lock batteries are at half-life, and outdoor activity is starting back up. Schedule the annual maintenance now.
December-February — Avoid for Outdoor Work
Reasons to delay non-emergency lock work:
- Outdoor temperatures below 30°F make adhesive-based lock body installation unreliable
- Door frames are contracted — strike plate alignment that's perfect in January will rub in May
- Frozen-lock emergencies dominate locksmith schedules; routine appointments take longer to book
- Salt and de-icer residue gets dragged inside and ruins clean install conditions
Exception: emergency work (lockouts, post-burglary) we handle anytime.
July-August — Avoid for Door Frame Work
Hot summer days expand door frames. A strike plate adjustment in August will create a too-loose fit in October when frames contract. Wait for September or do it in October.
Schedule by Service Type
| Service | Best Month | Avoid |
|---|---|---|
| Whole-home rekey | October, April | Anytime is OK |
| Smart lock installation | October | Below 30°F |
| High-security upgrade | October, April | Anytime is OK |
| Strike plate / hinge adjustment | September-October | July-August (frame expanded) |
| Cylinder service / lubrication | October | Below freezing |
| Master key system install | October-November | Anytime is OK |
| Commercial panic bar / access control | October-November | December (holiday closure) |
