Changing door locks in Palmdale runs $95 to $240 for most residential hardware, depending on whether you need a simple rekey or full hardware replacement. We’re Dunmore Locksmith, and we handle everything from a single front-door cylinder swap to complete rekeying of every exterior lock on a Palmdale tract home. Call (910) 714-4287 and a live person answers, day or night.
Palmdale’s high-desert climate and aging 1980s-to-2000s housing stock create lock problems you won’t find in the LA Basin. We know the difference between a lock that genuinely needs replacing and one that just needs the right adjustment, because we see these specific failures every week across Palmdale neighborhoods.
Why Dunmore Locksmith Is Palmdale’s Preferred Change Door Locks Company
Dunmore comes from old words for a great fort. A stronghold built to keep what’s inside safe. That’s the standard we bring to every lock change in Palmdale, and it’s backed by something most locksmiths won’t offer: a written 365-Day Done Right Promise. If the lock we install or rekey fails within a year, we return and fix it at no charge. Full stop.
Perry Osgood leads our team, and every technician we send to a Palmdale home is background-checked, identity-verified, and dispatched by name and photo before the visit.

Patio Door Lock Change in Palmdale
Patio Door Lock Change work in Palmdale typically runs $110 to $220, and it’s one of the more common calls we field because so many Palmdale homes were built with aluminum-framed sliders that have outlived their original hardware. The lock on a patio slider isn’t just a security point, it’s also the mechanism that keeps the door seated against the frame, and when that mechanism wears, the door either won’t lock firmly or won’t open without a fight.
Slider Lock Replacement
Most Palmdale patio sliders use a mortise-style latch mounted in the edge of the door. When the internal spring loaded hook or pawl wears down, the door can feel locked when it isn’t. We replace the latch assembly and rekey the cylinder to match your existing keys, so you don’t end up carrying a separate patio key on your ring.
Keyed Patio Door Cylinders
If your slider has a keyed cylinder that’s stiff or seized, the fix is usually straightforward: remove the old cylinder, clean the pocket, and install a new one. We stock Schlage and Kwikset cylinders sized for the aluminum door thickness common in Palmdale’s tract subdivisions. The whole job usually takes under an hour.
Door Lock Change in Palmdale
Door Lock Change jobs in Palmdale run $95 to $240 depending on hardware grade and cylinder type. A straightforward swap of a worn Kwikset or Schlage deadbolt on a standard exterior door usually sits at the lower end. Anything involving Medeco or Mul-T-Lock high-security cylinders pushes toward the upper end, and for good reason: those cylinders are pick-resistant and key-controlled, which matters to people who don’t want unauthorized key copies floating around.
Deadbolt Replacement
Deadbolts on Palmdale tract homes from the 1980s and 1990s are often builder-grade Kwikset or Schlage units that were never meant to last 30 years. We pull the old deadbolt, check the bore and strike alignment, and install a replacement that throws cleanly. If the frame has shifted, we address that too, because a new deadbolt in a misaligned frame will bind within weeks.
Full Lock Set Change
When you want every exterior lock changed at once, we do it fast and rekey everything to one key. That’s common after a roommate moves out, a tenant turnover, or a lost key incident. For a typical Palmdale single-family home with two or three exterior doors, expect $160 to $240 for the full set, including rekeying all cylinders to match.
Trusted Brands We Service in Palmdale
We’re factory-authorized to install and service Schlage, Kwikset, Medeco, and Abloy hardware. For Palmdale homeowners, that means we stock the common parts locally, and we can get high-security cylinders ordered quickly when a Plant 42 engineer asks for something above the standard residential grade. If you already have Kwikset or Schlage hardware on your doors, in most cases we can rekey it without replacing anything, which saves you money and keeps your existing keyway.
Common Change Door Locks Problems We See in Palmdale Homes
- Afternoon thermal binding on aluminum-framed doors. The 40 to 50 degree daily temperature swing makes aluminum frames expand and contract enough that a deadbolt throwing cleanly at 7 a.m. binds by 3 p.m. The lock isn’t broken. The frame moved. We realign the strike plate or hinge-side clearance instead of selling you hardware you don’t need.
- Mojave dust packed into pin and tumbler cylinders. Fine desert dust works its way into keyways and builds up until keys turn stiff or seize entirely. People often assume someone tried to break in. Usually it’s just dust, and the fix is a thorough cylinder cleaning and rekey, not a police report.
- Original builder-grade hardware from the 1980s to 2000s growth boom. Most Palmdale homes have original Kwikset or Schlage locks that are 20 to 35 years old. Internal springs fatigue, pins wear, and keys get sloppy. At that age, replacement is usually the honest answer, not another repair.
- Mortise locks on older Palmdale doors with obsolete cylinder formats. Some older homes here have mortise lock bodies with cylinder dimensions nobody manufactures anymore. A modern cylinder won’t drop into the existing pocket. We tell you straight whether yours can be fitted or whether the mortise body needs replacement too.

FAQs About Change Door Locks in Palmdale
No. What you’re describing is thermal binding, and it’s the most common repeat service call in Palmdale. The aluminum door frame expands in the high-desert heat and shifts the strike plate position just enough that the bolt catches. We fix it by adjusting the strike plate or hinge-side clearance, and sometimes we recommend replacing worn pins in the cylinder so the lock throws smoothly across the full temperature range. Call (910) 714-4287 and we’ll tell you if it’s an adjustment call or a lock replacement.
In most cases, we can rekey your existing Kwikset or Schlage hardware, and it runs $45 to $75 per cylinder. Rekeying means changing the internal pins so your old keys stop working and a new key operates the lock. It’s cheaper than replacing hardware, and it makes sense when the lock itself is still in good mechanical shape. If the lock is 20-plus years old with worn springs and sloppy key feel, we’ll tell you that replacement is the better long-term call.
In Palmdale, stiff or seized keys are usually caused by Mojave dust packed into the pin and tumbler cylinder. The fine desert grit works into the keyway and grinds against the pins until the key binds. Tampering can cause similar symptoms, so we check for both. If it’s dust, we clean the cylinder and rekey if needed. If there’s evidence of forced entry or picking, we’ll show you what we found and recommend replacement.
Air Force Plant 42 and the surrounding aerospace and defense industry employ thousands of people in Palmdale who hold active security clearances. Those residents understand physical security at a professional level, and they apply that mindset to their homes. That’s why we see more requests for pick-resistant Medeco and Mul-T-Lock cylinders, and ANSI Grade 1 deadbolts, in ordinary Palmdale tract houses than we do in comparable high-desert cities. We’re qualified to install and service all of them.
We handle patio slider locks, including the mortise-style latch assemblies common on aluminum-framed Palmdale sliders. We replace worn latch hooks, rekey keyed cylinders, and adjust the roller and track alignment when the door won’t seat firmly against the frame. Expect $110 to $220 for most patio slider lock work, and the written quote you get on the phone is the price you pay.
