Fast, Reliable Change Door Locks Across Simi Valley
If you need to change door locks in Simi Valley, the job usually costs between $95 and $260 depending on the hardware and whether we’re rekeying or replacing, and a technician can typically reach most neighborhoods within 30 to 45 minutes. A straight-forward single deadbolt replacement on a standard entry door runs $95 to $180, while a full rekey of multiple exterior locks runs $140 to $320 depending on cylinder count and key type. Call (910) 714-4287 and a live person answers, any hour, every day. We serve the entire valley, from the tract homes off Cochran Street to the newer builds in Wood Ranch and the condo complexes along Madera Road.
Simi Valley is not a city where you wait around for help from over the hill. The SR-118 corridor is the main artery in and out, and when it slows down, so does every locksmith coming from Moorpark or Thousand Oaks. Our Change Door Locks team knows this geography. We schedule Simi Valley jobs with local traffic patterns in mind, not a generic dispatch radius. That means a resident near Royal Avenue or a condo owner near the 93065 zip code gets a realistic arrival time, not an optimistic guess.
Why Dunmore Locksmith Is Simi Valley’s Preferred Change Door Locks Company
Dunmore Locksmith operates under the Threshold Group umbrella, serving Simi Valley residential and commercial customers since 2007. Every technician we send into Simi Valley is background-checked, identity-verified, and uniformed. Before the visit, you receive the technician’s name and photo. They show a photo ID badge at the door. If someone arrives who you were not told to expect, that visit is covered at no charge. That is The Threshold Standard, and it matters more in Simi Valley than most places because of how many homes here sit on quiet cul-de-sacs where a stranger at the door is genuinely unsettling.
We hear from Simi Valley customers who have been burned by bait-pricing locksmiths before. A $19 teaser becomes a $400 invoice once the technician is standing in the driveway. We do not do that. The price you get on the phone is the price on the invoice. Every job comes with the 365-Day Done Right Promise: a written guarantee on every lock change. If the work fails, we return at no charge. That is not a verbal pledge. It is printed on the work order. Perry Osgood, who leads Dunmore Locksmith, built this operation around a simple idea: you should know exactly who is coming to your door before you open it, and you should know exactly what the job costs before we start it.
Door Lock Installation in Simi Valley
Door lock installation in Simi Valley often means more than swapping one deadbolt for another. Most homes here were built between 1965 and 1990, and a large share still have original hollow-core entry doors and builder-grade Kwikset hardware that predates modern bump-resistant standards. When we install a new lock on a Simi Valley home, the first thing we check is whether the existing door prep even fits the new hardware. On many 1970s tract homes, the bore holes are worn oblong from decades of use, and the strike plate has been shimmed or bent so many times that a new deadbolt will not seat cleanly. A proper installation here means addressing the strike and the frame, not just the cylinder.
Replacement Deadbolts on Aging Tract Doors
Simi Valley homes from the aerospace-era building boom often have single-cylinder Kwikset deadbolts that are now 40 to 50 years old. These locks were never designed to resist bumping or picking. Replacing them with a modern Schlage or Medeco deadbolt usually runs $120 to $260 installed, including strike reinforcement. The job takes under an hour for a standard door, and we stock common finishes locally so the hardware matches the existing trim.
New Construction and Smart Lock Retrofits
For newer homes in Wood Ranch or the developments near Big Sky, we install smart locks and keypad deadbolts on standard prep doors. Many homeowners want a keypad for kids coming home from school or for housecleaners and dog walkers without handing out physical keys. A smart deadbolt install on a compatible Simi Valley door runs $180 to $320, and we configure the lock before we leave. No app troubleshooting after dark.
Patio Door Lock Change in Simi Valley
Patio door lock change in Simi Valley gets more calls than most people expect, and the reason is local. The valley’s inland climate pushes summer temperatures past 100°F, and that heat does two things to patio doors: the aluminum frames expand and contract, and the wood framing behind them swells. The result is a patio door lock that falls out of alignment, a latch that will not engage, or a handle that jams. On top of that, Santa Ana winds funneling through the Santa Susana Pass slam patio doors hard enough to bend flush bolts and twist sliding-door hardware. We replace patio door locks on sliding glass doors, French doors, and swing patio doors throughout Simi Valley, typically for $110 to $240.
Sliding Glass Door Lock Replacement
Most Simi Valley sliding patio doors rely on a small die-cast latch that wears out long before the door does. We replace these with mortise-style sliding door locks or surface-mount secondary locks that actually secure the panel. If the door has shifted in its track, we adjust the rollers before installing the lock so the new hardware engages properly. A sliding-door lock replacement runs $95 to $190.
French Door and Swing Patio Lock Work
French patio doors on Simi Valley homes often have two-point or three-point locking hardware that is no longer made. We match existing hardware to current production from Baldwin, Schlage, or Kwikset, or we retrofit with a modern multi-point system. These jobs run $160 to $320 because they involve aligning both doors and the astragal. Written price before we start, always.
Trusted Brands We Service in Simi Valley
Dunmore Locksmith is factory-authorized for Schlage, Kwikset, Medeco, and Abloy hardware, and we service Baldwin, Yale, and Mul-T-Lock as well. For Simi Valley customers, that means we stock common Kwikset and Schlage cylinders locally and can usually complete a standard lock change on the first visit without waiting for parts. When a Simi Valley condo association or apartment complex specifies a restricted keyway, we cut and register keys through the authorized Medeco or Abloy channel. No generic blanks, no unrecorded copies. That key control is a big deal in multi-tenant buildings where a single unauthorized duplicate compromises the entire complex’s security.
Common Change Door Locks Problems We See in Simi Valley Homes
- Heat-swollen door frames throwing deadbolts out of alignment. Summer days above 100°F make the wood frames on 1970s and 1980s tract homes swell and shift. The deadbolt throw no longer lines up with the strike plate, so the lock either will not throw or will not release. A straight rekey does not fix this – the strike has to be repositioned or reinforced.
- Santa Ana wind damage to strike plates and lock seating. Every fall, winds through the Santa Susana Pass slam doors hard enough to bend strike plates and seat deadbolts in stressed positions. We see a seasonal spike in no-latch and lockout calls from homeowners whose doors simply will not stay closed or will not unlock.
- Original builder-grade Kwikset deadbolts past their useful life. Homes built for aerospace and defense workers in the 1970s and 80s often still carry the original single-cylinder Kwikset deadbolt. These locks are worn, easily bumped, and increasingly prone to internal failure. Rekeying them is sometimes enough; replacing them is often the better call.
- Restricted-key breakdowns in multi-tenant complexes. When a Simi Valley apartment or condo resident copies a restricted key at an unauthorized shop, the entire building’s key control is compromised. We rekey and reissue under the building’s original restricted system so property managers regain control without replacing every lock in the complex.

FAQs About Change Door Locks in Simi Valley
Yes. We work on HOA-owned doors throughout Simi Valley every week, and we use non-destructive entry methods whenever a lock has failed or keys are lost. That means we disassemble the lock through the cylinder and latch, not the door. The door and frame remain untouched. We also handle the key hand-off. If your HOA requires a copy of the new key, we provide it in a sealed envelope for the property manager. The written price covers the full job, and the 365-Day Done Right Promise applies even when the HOA owns the door. Call (910) 714-4287 and we will walk you through what your HOA’s rules allow before scheduling.
Replace it. The builder-grade Kwikset deadbolts installed on 1970s Simi Valley tract homes were never designed to resist bumping or picking, and after 40 to 50 years they are worn past their useful life. Rekeying changes the key but does nothing about the worn cylinder, the sloppy bore, or the outdated pinning. For most Simi Valley homes with original hardware, we recommend a bump-resistant Schlage or Medeco deadbolt with a reinforced strike plate, and we rekey the remaining exterior cylinders to match. Replacement and full rekey typically runs $180 to $320. Call (910) 714-4287 and tell us the year your home was built. We will give you a straight recommendation and a written price.
Santa Ana winds. Every autumn, wind gusts funneling through the Santa Susana Pass slam exterior doors hard enough to bend strike plates and shift deadbolt alignment. The deadbolt no longer seats cleanly into the strike, so the door will not latch or the key will not turn. We see this seasonally across Simi Valley, especially on north-facing doors and on homes near the foothills. The fix is usually a strike plate replacement plus a deadbolt realignment, often $95 to $160. If the frame has swollen or warped, we may need to adjust the door itself. Call (910) 714-4287 and we will diagnose it over the phone before sending anyone out.
Yes. We change patio door locks on sliding glass doors, French doors, and swing patio doors throughout Simi Valley, including the tract subdivisions off Cochran and the newer homes in Wood Ranch. The local heat and Santa Ana winds put extra stress on patio hardware, so we check frame alignment and roller condition before installing the new lock. A sliding-door lock replacement runs $95 to $190; a French door multi-point replacement or retrofit runs $160 to $320. All prices are written before work starts. Call (910) 714-4287 and describe your patio door. We will tell you what the job likely costs on the spot.
Yes, but the process is different. Restricted key systems, like Medeco or Abloy, require that keys be cut only through authorized channels. We are factory-authorized for both, so we can change your unit lock and cut new keys under the building’s existing keyway. We coordinate with the property manager or owner to ensure the new keys are registered in the building’s key control system. A restricted-key unit lock change in Simi Valley typically runs $180 to $320, depending on the cylinder type. Call (910) 714-4287 and have your building’s key code or property manager’s contact info ready. We will handle the authorization so you do not have to.
