Parkwood’s unincorporated San Joaquin County home stock has a problem you won’t hear about from a national call center: builder-grade Kwikset locks installed in the 1960s through 1980s were often never rekeyed after handover. In too many cases, a builder’s key from decades ago still opens a door that has changed owners two or three times. That’s not a lock that’s broken. It’s a key-control gap, and it’s the most common reason we get called to Parkwood homes.
Why Dunmore Locksmith Is Parkwood’s Preferred Change Door Locks Company
We’re part of Threshold Group, the network built around one idea: you should know exactly who is coming to your door before you open it. Every technician we send to Parkwood has been background-checked, identity-verified, and photo-badged under what we call the Threshold Standard. Before the visit, we send you the technician’s name and photo. When they arrive, they show a photo ID badge at the door. If someone shows up who you weren’t told to expect, that visit is covered at no charge.
Perry Osgood leads our field crews, and the work carries a 365-Day Done Right Promise: a written guarantee on every repair, and if the repair fails, we return at no charge. Parkwood homeowners call us for a specific reason. They’d rather pay a little more and know the person at the door is who we said it would be, and that the price we quoted on the phone is the price on the invoice. That’s the whole point of our Change Door Locks team.
Patio Door Lock Change in Parkwood
A patio door lock change in Parkwood usually means the sliding glass door at the back of a ranch-style or tract home, and it’s a job we handle all year. The original lock is often a cheap latch that was never meant to stop a determined push. What you need is a keyed or keypad-controlled lock, and we install both.
Sliding Glass Door Hardware
Most Parkwood sliding doors have either a surface-mount latch or a mortise lock built into the frame. A standard patio door lock change runs $120 to $190 unkeyed, and $180 to $260 if you want a keyed cylinder or a smart keypad. We stock parts locally for Parkwood jobs, so we’re not waiting on a warehouse.
When Heat Warps the Track
San Joaquin Valley summers above 100°F expand the aluminum frame and the steel latch, and a sliding door that locked easily in March can refuse to latch in July. We realign the strike, replace the latch if it’s bent, and test it through a full open-close cycle before we leave.
Door Lock Change in Parkwood
A door lock change in Parkwood replaces the entire visible hardware assembly: knob, deadbolt, or both. If your lock is original to the house, it’s likely a builder-grade Kwikset from the 1960s to 1980s, and the internal pins have never been changed. That means the builder’s key may still work, and the cylinder is probably packed with mineral scale from hard well-water. We pull the cylinder, flush it, and install new hardware.
Entry Knob and Deadbolt Replacement
Replacing a knob alone runs $95 to $140. A deadbolt alone runs $110 to $175. A matched knob-and-deadbolt set, installed and keyed alike, runs $180 to $240. Parkwood homeowners often upgrade to an ANSI Grade 1 deadbolt with a bump-resistant pin, which is the single best dollar-for-dollar improvement you can make on an older entry door.
Rekey, Replace, or Both
Rekeying changes the internal pins so old keys stop working but keeps the existing hardware. Replacement swaps the whole unit. In Parkwood, we commonly do both: rekey one door to keep a mortise lock that’s in good shape, and replace the front entry with a Grade 1 unit. You’ll get one key that operates everything.
Trusted Brands We Service in Parkwood
We’re factory-authorized on Schlage, Kwikset, Medeco, and the full Threshold Group hardware line, and we keep the common cylinders and strike plates for Parkwood’s 1960s-to-1980s tract homes on the truck. If your lock is a builder-grade Kwikset from that era, we can rekey it same day, or replace it with a Schlage B560 or B660 deadbolt that survives San Joaquin Valley heat without warping. No waiting on a parts order. No “we’ll come back next week.”
Common Change Door Locks Problems We See in Parkwood Homes
- The builder’s key still works. Many Parkwood homes from the 1960s – 1980s were never rekeyed after the original builder’s-key handover. A key that came with a new house thirty years ago can still open the front door today, even if the home has changed owners twice since. Rekeying is the fix.
- Sticky deadbolts in July and August. Above 100°F, the steel bolt and the strike plate expand at different rates. A deadbolt that glides in March can seize in July, and we see it every summer in Parkwood. We file or replace the strike plate and test the throw in both directions.
- Corroded cylinders in Tule fog season. From November through February, dense Tule fog pushes sustained moisture against exterior lock cylinders. The pin tumblers bind, the key gets hard to turn, and by January the keyway is often corroded enough to slow a standard pick attempt. We flush the cylinder and re-lubricate with a dry graphite that survives the season.
- Mineral-scaled keyways from hard well-water. Parkwood’s well-water households deal with mineral-laden irrigation runoff, and over years that scaling builds up inside the keyway itself. Bump keys and picks run slow, and keys feel gritty when inserted. We flush before rekeying, every time, because a scaled cylinder will ruin a brand-new set of pins within a season.

FAQs About Change Door Locks in Parkwood
It means your locks were never rekeyed after the builder handed over the keys, which is common in Parkwood’s 1960s-to-1980s tract homes. Anyone who ever held that builder’s key can still open your door. You need a rekey, not necessarily new hardware, and we can tell you which locks are worth keeping and which are too corroded to save. Call (910) 714-4287 for a same-week appointment.
Probably not the lock itself. San Joaquin Valley heat above 100°F thermally expands the steel bolt and shifts the strike plate, and a deadbolt that throws cleanly in winter can bind in summer. We realign or replace the strike and test the throw through a full temperature cycle. If the lock is also worn internally, we’ll tell you, and the written quote will be before any work starts.
Tule fog from November through February pushes sustained moisture into exterior lock cylinders, corroding the pin tumblers and making keys bind. Parkwood’s hard well-water compounds it with mineral scaling inside the keyway. We flush the cylinder, replace any corroded pins, and re-lubricate with a dry graphite that won’t evaporate. Same-day service is available in Parkwood.
Yes. If you already have a smart lock or a keypad entry system, we can match a new deadbolt or knob to the existing system so one code operates every door. We’ve done this on Parkwood homes where the front entry was a decades-old Kwikset and the patio door had a separate smart lock. We brought both onto the same keypad scheme, and the owner got one code for the whole house.
Yes, especially if the lock was never rekeyed and the keyway shows mineral scaling. A new ANSI Grade 1 deadbolt with a bump-resistant pin costs $110 to $175 installed, and it’s a far stronger defense than a 1970s builder cylinder. We can keep the old knob and rekey it, or replace the whole set. Call (910) 714-4287 and we’ll give you a written quote on the spot.
