Why Dunmore Locksmith Is Concord’s Preferred Change Door Locks Company
Concord homeowners call us for a specific reason: they want to know who is coming to their door before they open it. That’s the Threshold Standard at work. Every technician we send to a Concord address is background-checked and identity-verified, and you get that technician’s name and photo before the visit. When he or she arrives in a marked uniform, a photo ID badge is shown at the door. If the person standing there isn’t the person we told you to expect, the visit is covered at no charge. That’s not marketing language. It’s a written condition of how we operate.
Dunmore Locksmith is the Concord face of Threshold Group, the independent locksmith network built on that one idea. We’ve operated under the Threshold umbrella since 2007. The name comes from old words for a great fort, a stronghold built to keep what is inside safe. That’s the job in Concord: not just swapping hardware, but making sure the lock change actually secures the door, the frame, and the people behind it. Every job carries our 365-Day Done Right Promise in writing. If the repair fails within a year, we return at no charge. That guarantee is stamped on your invoice, not buried in a terms page.
Perry Osgood leads our team, and a live person answers our phone 24 hours a day, every day of the year. When a Concord homeowner calls at 11 p.m. about a deadbolt that won’t throw, they get a human, not a recording. The full price is quoted on the phone before anyone is dispatched. That price is the price on the invoice. No call-out surcharge added on arrival. No estimate that balloons once the work starts.
Change Lock Cylinder in Concord
A change lock cylinder job in Concord means removing the old key cylinder from your existing lock body and installing a new, pinned cylinder, often because the original 1960s or 70s brass unit is too worn to rekey. In Concord’s ranch-style tract homes, we regularly see Kwikset and Schlage cylinders from the Nixon era that still turn, but their internal pins are so rounded they can’t hold a new key pattern. You’ll hear a real locksmith say the cylinder is “shot.” What that means: no amount of repinning will make it reliable again. The fix is a new cylinder matched to your existing hardware, or a full lock replacement if the lock body is equally worn.
Cylinder swap versus full replacement
If your lock body is solid and only the cylinder is worn, we swap the cylinder. In Concord, this runs $95 – $190 depending on the keyway and brand. If the deadbolt’s internal mechanism is also binding from 50 years of use, replacement is the honest call, usually $150 – $240 for a standard residential deadbolt installed.
Matching original Concord hardware
Many Concord homes have original mortise-style entry sets or discontinued Kwikset keyways. We stock common Schlage and Kwikset cylinders and can order Medeco or Yale high-security cylinders for same-week installs. You don’t need to replace your whole entry set just because a cylinder gave out.
Door Lock Installation in Concord
Door lock installation in Concord often involves more than screwing a new deadbolt into an existing hole, because the door itself has moved. The city’s inland Diablo Valley heat regularly pushes past 100°F in July and August, and those sustained temperatures expand the wooden door frames on 1955 – 1980 ranch homes enough to shift deadbolt throws out of alignment. A new lock installed without fixing that alignment will bind by Labor Day. We check the frame, the strike plate, and the door’s sag before we drill a single hole. Then we install the lock and the adjustment holds.
Full deadbolt and knobset replacement
A standard Grade 2 residential deadbolt installation in Concord runs $140 – $240, including the hardware. For an ANSI Grade 1 deadbolt, the price climbs to $220 – $380. We quote the full amount before work begins, and that number includes drilling, strike plate alignment, and cleanup.
Upgrading from hollow-core doors
Concord’s original hollow-core front doors are a known weak point. A brand-new Medeco deadbolt mounted in a sagging hollow-core door is still a weak door. We’ll tell you straight if your door is too far gone for a lock upgrade to matter, and we’ll give you the lock numbers anyway so you can decide with facts, not pressure.
Trusted Brands We Service in Concord
We’re factory-authorized to install and service Schlage, Kwikset, Medeco, Yale, Baldwin, Mul-T-Lock, Sargent, and Abloy hardware, from basic pin-tumbler rekeying to high-security commercial cylinders. For Concord customers, that means we stock the exact cylinder formats and pinning kits that match the city’s original 1960s and 70s entry hardware. If you’re replacing a worn Kwikset deadbolt on a Holbrook Heights rancher and want your back door key to keep working, we can match the new lock to the existing keyway. If you want to step up to Medeco or Yale for better drill resistance, we’ll give you honest numbers for that upgrade too.
Common Change Door Locks Problems We See in Concord Homes
- Summer heat expansion jams deadbolts. Concord’s July and August temperature spikes past 100°F expand wooden door frames enough to push deadbolt throws out of strike-plate alignment. This produces the predictable late-summer wave of lockout calls across Dana Estates and Holbrook Heights.
- Worn 1970s Kwikset and Schlage cylinders won’t rekey. The original brass and pot-metal cylinders in Concord’s ranch homes have internal pins so rounded they can’t hold a new key pattern. A full cylinder replacement is often the only durable fix.
- Aluminum sliding-door latches bind seasonally. Concord’s ubiquitous 1970s aluminum slider frames expand in sustained 95 – 105°F heat, which binds latches and leads homeowners to force them, damaging the mortise mechanism inside.
- Forgotten or unaccounted-for keys after a move. Concord has a very active resale market for older ranch homes. New owners rarely know how many keys were distributed over 40 years. Changing or rekeying the locks closes that gap.

FAQs About Change Door Locks in Concord
It depends on the cylinder’s internal wear, and we’ll tell you straight once we see it. Many original 1970s Kwikset cylinders in Concord have pins so rounded they can’t hold a new key pattern, which means rekeying is not a durable fix. If the cylinder is still tight, rekeying runs $25 – $45 per cylinder. If it’s shot, a cylinder change or full replacement is the honest call, usually $95 – $240. Call (910) 714-4287 and we’ll give you a written price after a quick inspection.
Because Concord sits deep in the inland Diablo Valley, where summer temperatures routinely spike past 100°F while coastal East Bay cities like Walnut Creek stay 30 degrees cooler. That sustained heat expands the wooden door frames on your ranch home enough to push the deadbolt throw out of strike-plate alignment. It’s a seasonal, climate-driven failure, not random wear. We fix the alignment and the lock together so you don’t repeat the cycle every August.
Rekeying changes the internal pins so your old keys no longer work; the existing cylinder stays in the lock. Changing the cylinder removes the old cylinder entirely and installs a new one, which is the right move when the original unit is too worn to hold a new pin pattern. In Concord’s older housing stock, cylinder changes are more common than rekeys because the original brass and pot-metal hardware has aged beyond repinning.
Yes, and this is a common request in Concord’s ranch homes where owners want one key for front and back. We stock Schlage and Kwikset cylinders in the keyways most common to 1960s and 70s Concord hardware, and we can pin the new deadbolt to match the existing back-door key. You get one working key for the whole house. Call (910) 714-4287 and we’ll confirm the keyway match before we order any parts.
Yes. We open most Concord residential locks without damaging the door or frame, using the same commercial-grade tools we’d use on a high-security job. If the lock is already failing, we’ll tell you the replacement cost before we do anything beyond getting you inside. And because the full price is quoted on the phone before dispatch, there’s no surprise bill once the door is open.
