Dunmore Locksmith is the Threshold Group member business serving Pleasant Hill with lock changes, rekeying, and full residential locksmith - Pleasant Hill work. We’ve held that role since 2007, and every technician who comes to your door is background-checked, identity-verified, and sent to you by name and photo before the visit.
Why Dunmore Locksmith Is Pleasant Hill’s Preferred Change Door Locks Company
Pleasant Hill homeowners call us because we treat the whole property, not just the front door. That matters here more than in most East Bay cities. The 1960s and 1970s ranch and split-level tract homes that define Pleasant Hill often have detached garages, workshops, and gate locks on separate keys, and owners want all of it keyed alike in one visit. We plan for that from the first phone call.
Every job carries the 365-Day Done Right Promise in writing. If a lock change fails within a year, we come back and make it right at no charge. That guarantee is stamped on the invoice, not buried in fine print. It’s a real commitment, and it’s why homeowners who want a technician they can verify tend to choose us. The Threshold Standard is how we earn trust: background-checked, photo-badged, uniformed, and introduced by name and photo before arrival. If someone shows up who you weren’t told to expect, that visit is covered at no charge.

Change Lock Cylinder in Pleasant Hill
Change lock cylinder work in Pleasant Hill means replacing the internal pin and tumbler core inside your existing lock body, so the old keys stop working and new keys take over, without replacing the entire hardware set. This is the right move when the lock body is still sound but keys have gone missing, a tenant or roommate has moved out, or you’ve bought a 1960s ranch home and don’t know how many copies of the old key are floating around. On Pleasant Hill’s aging Schlage and Kwikset hardware, a cylinder change typically runs $75 to $160 per lock, depending on the brand and whether the cylinder is standard or high-security.
Our Change Door Locks team stocks cylinders for Kwikset, Schlage, Yale, and Medeco on the truck, so most Pleasant Hill jobs finish in one visit.
When a cylinder swap beats a full lock replacement
If your deadbolt still turns smoothly and the latch aligns, changing only the cylinder is cheaper and faster than swapping the whole lockset. Original Schlage and Kwikset lock bodies from the 1970s are often mechanically fine even when the cylinders are worn. In Pleasant Hill’s heat, worn cylinders fail faster because the brass pins expand and bind in high summer temperatures.
Keyed alike during the cylinder change
When we change a cylinder on one door, we can pin it to match the rest of the property’s keys. That means the front door, back door, workshop, and gate all open with the same key. For Pleasant Hill owners with outbuildings, this is the single most requested upgrade.
Door Lock Installation in Pleasant Hill
Door lock installation in Pleasant Hill means removing the old lockset entirely and fitting a new knob, lever, deadbolt, or smart lock into the door. It’s the better choice when the lock body is worn, the finish is failing, or you want keypad entry on a detached workshop. A standard deadbolt or knob installation ranges from $95 to $180 per door. A keypad or smart lock install, including wiring-free models from Kwikset or Yale, runs $160 to $280. The full price is quoted on the phone before anyone rolls, and that’s the number on the invoice.
New deadbolts for heat-warped doors
Doors in Pleasant Hill shift with the Diablo Valley summer. A deadbolt that binds each July has often been misaligned by a swollen jamb. During installation, we adjust the strike plate and deepen the pocket so the new deadbolt throws cleanly through the full range of seasonal movement. That adjustment is part of the install, not an upsell.
Smart locks on detached workshops
Many Pleasant Hill properties have a workshop or detached garage set back from the house. We install keypad and smart locks out there so you don’t need a separate key ring. Baldwin and Kwikset both make keypad deadbolts that fit standard 2-1/8-inch crossbores, which covers most 1970s tract-home doors.
Trusted Brands We Service in Pleasant Hill
We’re factory-authorized on Schlage, Medeco, Mul-T-Lock, Abloy, Baldwin, Yale, Kwikset, and Sargent hardware. For Pleasant Hill’s housing stock, that matters: the original Schlage and Kwikset locksets on 1960s and 1970s ranch homes have specific pin and tumbler stacks that generic parts don’t match. Our trucks carry genuine cylinders and tailpieces for Kwikset, Medeco, and Yale, along with Baldwin trim for owners upgrading a front entry. That stock means we don’t have to order a part and come back a second day.
Pleasant Hill homeowners tell us the most common request is matching a new Yale or Kwikset deadbolt to the existing Schlage keyway so one key works every door on the lot. We do that on the first visit.
Common Change Door Locks Problems We See in Pleasant Hill Homes
- Worn original cylinders from 1960s and 1970s locksets. These Schlage and Kwikset pin stacks were installed when the house was built. After 50-plus years of use and heat-driven expansion, the pins no longer seat cleanly and keys start to stick or spin without turning the bolt.
- Detached workshop and gate locks on different keys. Many Pleasant Hill properties have a shop or side gate that was keyed separately at some point and never matched back to the house. Old keys stay in circulation, and owners want the whole property reduced to one key.
- Summer deadbolt misalignment from frame swelling. When valley temperatures pass 100°F, wooden door jambs expand. The deadbolt that worked in October binds in July, or worse, doesn’t fully throw and the door pops open under pressure.
- Keys that no longer match after a tenant or sale turnover. The apartment and condo corridor near the Contra Costa Centre BART station cycles through tenants year-round. Property managers need consistent rekeying, and homeowners who buy from a previous owner never know how many key copies are out there.

FAQs About Change Door Locks in Pleasant Hill
Yes, this is the core of what we do in Pleasant Hill. We can rekey the house, detached workshop, and gate cylinders to one keyed-alike set in a single visit, as long as the cylinders are compatible. Most original 1970s Schlage and Kwikset locks on Pleasant Hill tract homes share standard pin and tumbler configurations, so we can pin them all to match. If a workshop lock is too worn to rekey reliably, we’ll change the cylinder on the spot and pin it to match. We handled a call off Pleasant Hill Road near Paso Nogal Park where a homeowner’s detached workshop had a 1970s Kwikset knob that no longer turned with the house key after a summer of 100°F-plus heat swelled the frame. We rekeyed the Kwikset cylinder in the original lockset to match the home’s Schlage deadbolt keyway and adjusted the strike plate, so one key now opens the front door, back door, and shop. Call (910) 714-4287 and we’ll tell you in five minutes whether your existing hardware can be keyed alike.
It’s usually the frame, not the lock. Pleasant Hill’s inland Diablo Valley location produces summer highs above 100°F, and wooden door jambs expand in that heat. The deadbolt then hits the edge of the strike plate instead of sliding into the pocket. If the key still turns smoothly in the cylinder, the lock itself is likely fine. We fix this by adjusting the strike plate and sometimes shimming or reshaping the pocket so the bolt throws cleanly through the full summer-to-winter movement range. Call (910) 714-4287 for a quick diagnosis and a written quote before we come out.
No, drilling is a last resort and we almost never need it on Schlage or Kwikset locks. If you have the working key, we can disassemble the lock and rekey or replace the cylinder without damaging the door or hardware. If you’ve lost all keys, we can often impression or pick the cylinder open first. Drilling only comes up when a lock is seized beyond picking, and we’ll tell you that on the phone before we touch anything. The replacement cylinder cost is part of the written quote, so there’s no surprise after the fact.
Rekey the lock body if it’s still in decent mechanical shape; replace it if the deadbolt binds, the finish is failing, or you want keypad entry. Pleasant Hill’s 1960s and 1970s Schlage and Kwikset lock bodies are often still sound, even when the cylinders are worn and the keys are old. Rekeying costs less than replacing, and it solves the security question of who holds old keys. If the deadbolt has been misaligned by repeated heat-driven frame swelling and the internal parts are loose, replacement is the better long-term call. We’ll give you an honest recommendation with the price attached, and both options carry the 365-Day Done Right Promise.
Yes. We install keypad and smart deadbolts on detached workshops, garages, and gates throughout Pleasant Hill, including the hillside lots east of Paso Nogal Park. Most 1970s doors have a standard 2-1/8-inch crossbore, so Kwikset and Yale keypad deadbolts fit without router work. We’ll also match the smart lock to your existing house keyway if you want a physical backup key that still works everywhere. A keypad install on a workshop typically runs $160 to $280, quoted in writing before we start. Call (910) 714-4287 and describe the door; we’ll tell you if it’s a simple swap or a custom bore.
