Fast, Reliable Change Door Locks Across Windsor
If you need to change door locks in Windsor, the job typically costs between $65 and $185 for a standard knob or deadbolt rekey, and $120 to $300 for a full new deadbolt installation on a pre-hung 1990s door. Most Windsor calls are completed the same day, often within 60 to 90 minutes of your phone call. We know this town’s housing stock well: the planned subdivisions off Brooks Road, the older ranch-style homes on the rural fringe, and the short-term rentals near the Town Green. The locks on those doors were installed when Windsor incorporated in 1992 or shortly after, and many of them have never been touched since. Call (910) 714-4287 and you’ll get a live person who can tell you exactly who is coming to your door and what the job will cost before anyone is dispatched.
Why Dunmore Locksmith Is Windsor’s Preferred Change Door Locks Company
Windsor homeowners call us because we do not make them guess. Every technician who comes to your home in the Brooks Creek subdivision or anywhere between Shiloh Road and the Russian River is background-checked, identity-verified, and sent to you by name and photo before the visit. That is the Threshold Standard, and it matters more than most people realize until someone knocks on their door claiming to be from a locksmith company and the homeowner has no way to verify it. Perry Osgood leads our team with a simple rule: the person you are told to expect is the person who shows up, in a marked uniform, with a photo ID badge you can see before you unlock the door.
We answer the phone live, 24 hours a day. Not a voicemail, not a chatbot. A real human in the San Francisco Bay Area office who can schedule a Windsor technician while you’re still on the line. Every price goes in writing before any work starts, and the quote you get is the price on the invoice. No call-out surcharge added on arrival. No estimate that inflates after the lock is apart. If the repair fails within 365 days, we return at no charge and make it right. That is the Done Right Promise, stamped in writing on every job.
The Windsor crew knows the specific quirks of this town’s doors. We know the 1998 builder-grade Kwiksets in the subdivisions off Arata Lane. We know the stickiness that hits exterior cylinders every August when the heat bakes the lubricant out. And we know the short-term rental homes near the golf course where owners need smart locks working with existing door preps, not a sales pitch for replacing everything.
Change Lock Cylinder in Windsor
Changing a lock cylinder in Windsor usually means swapping the internal pin-and-tumbler core so the old key no longer works, while keeping your existing hardware in place. For a Windsor home built between 1992 and 2005, a standard cylinder change runs $65 to $115 for a Kwikset or Schlage B-series knob or deadbolt. If the cylinder is seized from years of Sonoma County heat and winter rain, or if you want a bump-resistant ANSI Grade 1 cylinder, expect $90 to $140. We stock common cylinders for Windsor’s dominant builder hardware, so most cylinder changes happen in one visit.
When a cylinder change beats a full replacement
If the lock body is still solid and the finish matches your other hardware, you do not need a whole new deadbolt. We pull the old cylinder, install a new one with fresh pins matched to a new key, and the old key is dead. That is the right fix for a resale closing, a divorce, a roommate departure, or a lost key where you do not want to replace every lock on the house.
Builder’s key still turns your lock
A lot of Windsor homes have never been rekeyed since the day a builder’s crew locked up for the final inspection. That means at least one key you have never seen still opens your front door. We see this on nearly every 1990s resale in this town. A cylinder change kills that risk in 20 minutes.
Door Lock Installation in Windsor
Door lock installation in Windsor means a new deadbolt, knob, lever, or smart lock mounted into an existing door prep, or a fresh bore in a door that never had one. Standard deadbolt installation on a Windsor pre-hung door runs $120 to $220, including the labor and a new Kwikset or Schlage deadbolt. For a smart lock retrofit, like a Schlage Encode or August on a 1990s door, expect $180 to $300 depending on backset compatibility and whether we need to enlarge the bore. New bore work on a solid-core door adds $40 to $80.
Smart lock retrofit on 1990s preps
Windsor’s short-term rental market has made smart lock installation one of our most common jobs. The challenge is not the lock itself; it is the door. Homes built in the 1990s and early 2000s typically have a 2-3/8 inch or 2-3/4 inch backset with a 2-1/8 inch bore. Some smart locks fit those preps cleanly. Some do not, and the result is a misaligned bolt that binds or a loose housing that wobbles every time a guest enters. We verify compatibility against your existing prep before we install anything, and we tell you if a different model will fit better.
Upgrading builder-grade hardware
If your Windsor door still has the original Kwikset or Schlage B-series deadbolt from the Clinton-era building boom, it has likely been turning for 25 to 30 years. The tailpiece wears, the bolt grows sloppy, and the cylinder gets grainy in the heat. A new ANSI Grade 1 deadbolt is a different animal. We install them with reinforced strike plates on 1990s door frames too, so the deadbolt actually throws into solid wood.
Trusted Brands We Service in Windsor
We are factory-authorized on the hardware Windsor homes actually use. That means Schlage and Kwikset deadbolts for everyday security, plus Medeco and Abloy when a Windsor homeowner or rental owner asks for high-security cylinders that cannot be duplicated at a hardware store. We keep common Kwikset and Schlage cylinders, tailpieces, and strikes in our Windsor service vehicles, so we rarely have to leave a job half-done and come back. If your lock needs a brand-specific part that is not in stock, we tell you before we start, not after the lock is apart.
Common Change Door Locks Problems We See in Windsor Homes
- Builder’s key still works after a resale. The new owner on Antelope Way or in the Vintage Greens subdivision assumes the locks were changed at closing. They were not. The old key, or the builder’s master key, still turns the cylinder. We rekey or change the cylinder the same day.
- August stickiness in exterior cylinders. Windsor’s dry summer heat evaporates the light lubricant inside lock cylinders. By late August, keys drag, pins hang, and deadbolts bind. We clean and re-lubricate with a graphite or Teflon formula that holds up to the heat, or we swap the cylinder out entirely.
- Smart lock misalignment on 1990s door preps. The bore and backset on a 1990s pre-hung door do not always match modern smart lock templates. The bolt misses the strike plate by a fraction, or the housing rides loose. We correct the prep before mounting, so the bolt throws clean every time.
- Warped frames on older ranch-style homes. The heavy winter rain and dry heat cycling on Windsor’s rural fringe warps wooden door frames over decades. The deadbolt no longer lines up with the strike. We realign the strike plate and, when needed, reinforce the frame so the lock actually engages.

FAQs About Change Door Locks in Windsor
If the deadbolt still turns smoothly and the bolt throws fully into the strike plate, rekeying is enough, and it runs $65 to $95 in Windsor. But if the cylinder binds, especially after a dry summer, or if the deadbolt has visible play in the throw, replacement is the better call, and a new Kwikset or Schlage deadbolt installed runs $120 to $220. Call (910) 714-4287 and we’ll tell you which applies to your door before we touch anything.
Almost always, yes. Most Windsor rental homes were built in the 1990s or early 2000s with standard 2-1/8 inch bores and a 2-3/8 inch or 2-3/4 inch backset. Some Schlage Encode and August models fit those preps directly; others need minor adjustment. We verify compatibility against your specific door before installing, and the typical retrofit runs $180 to $300. Call (910) 714-4287 with your door’s backset measurement if you have it, or we’ll check it on site.
A keypad deadbolt with a remote-access app is the most practical setup for Windsor homeowners who want to lock or unlock from a distance during a future evacuation or when a neighbor needs to check the house. For most 1990s doors, we recommend a Schlage Encode or August retrofit, and the installed cost runs $180 to $300. In the Kincade Fire evacuation, Windsor was the only entire incorporated city in Sonoma County placed under mandatory evacuation. That experience changed how people here think about their locks. Call (910) 714-4287 and we’ll match a lock to your existing door prep.
Windsor’s warm, dry summers evaporate the light lubricant inside exterior lock cylinders, leaving pins to drag and the key to bind. By late August, the cylinder is effectively running dry. The fix is a thorough cleaning and re-lubrication with a heat-stable formula, or a straight cylinder change for $65 to $115 if the pins are too worn. Call (910) 714-4287 and we’ll get it turning smoothly before the fall rains arrive.
In almost every case, yes. We open standard Kwikset and Schlage pin-tumbler locks on Windsor homes without drilling by using non-destructive entry tools and techniques. Drilling is a last resort for high-security cylinders or severely seized locks, and we tell you before we do it. Lockout calls in Windsor are quoted on the phone before we dispatch anyone, and the price is the invoice price. Call (910) 714-4287 day or night.
