Why Dunmore Locksmith Is Orange’s Preferred Change Door Locks Company

Dunmore comes from old words for a great fort, a stronghold built to keep what is inside safe. That’s the standard we hold ourselves to in Orange. We’re part of the Threshold Group, serving customers since 2007, and we answer the phone with a real human every time you call. Our Orange customers tell us the same thing: they know who’s coming to the door before they open it.

Every technician who knocks on an Orange door has been background-checked and identity-verified under what we call the Threshold Standard. Before the visit, you get the technician’s name and photo sent to your phone. When they arrive, they’re in a clean marked uniform with a photo ID badge shown at the door. If someone shows up you weren’t told to expect, that visit is covered at no charge.

We work on schedule and we work fast, but we don’t rush the important part: figuring out whether your lock genuinely needs replacing or just a rekey. In Orange’s older neighborhoods, that distinction saves people hundreds of dollars. Every job is covered by our 365-Day Done Right Promise. If a repair fails within a year, we return at no charge. Written on every job. No fine print.

Change Lock Cylinder in Orange

Change Lock Cylinder work in Orange is the repair we recommend most often for Old Towne mortise locks that still function but need modern security. The cylinder is the part where the key enters. On a standard 1950s-1970s tract home east of the 55, swapping a cylinder is straightforward: remove the old pin-tumbler cylinder, install a new one, cut new keys. It typically runs $85 to $150 per lock.

On a 1920s Craftsman bungalow off North Glassell, changing the cylinder is a different trade skill. The original mortise lock box stays in the door. We insert a modern keyed cylinder into the existing 1⅛” or 1¼” face opening, preserve the period faceplate, and you keep the original skeleton key as a backup if you want it. That conversion runs $160 to $320 depending on cylinder vintage and finish.

When you need this: after a roommate, tenant, or caregiver moves out and you want new keys without replacing the whole lock. Also after a lost key, a break-in attempt, or when you buy an Old Towne bungalow and have no idea who still holds keys. If the cylinder body itself is worn or the vintage size is wrong, the lock won’t latch even with new keys, and we’ll tell you that before touching the hardware.

Mortise cylinder conversion

We keep mortise cylinder inserts in the correct vintage face sizes most common to Orange’s Old Towne stock. The original faceplate and box stay untouched for historic-character compliance. This is not a job we recommend attempting without a trained locksmith; the internal parts are under spring tension and the cylinder timing matters.

After a key loss or tenant change

If you own a rental near Chapman University, changing the lock cylinder between tenants is cheaper than a full replacement and gives you control over key copies. We can key multiple cylinders alike so one key works the front and back doors.

Door Lock Installation in Orange

Door Lock Installation in Orange means fitting a complete new lockset where none exists, or replacing a failed lock outright. In the tract neighborhoods between Katella and Tustin Avenue, that’s often a standard knob-and-deadbolt pin-tumbler set on an interior or exterior door. We carry Schlage and Kwikset hardware in the van, and typical installation runs $120 to $240 per door including the hardware for a basic grade-2 residential lock.

In Old Towne, door lock installation is rarely “standard.” The original doors are often 1¾-inch solid fir with mortise pockets cut for lock bodies that haven’t been manufactured in decades. A big-box knob-and-deadbolt set forced onto a mortise-lock door means cutting away the original faceplate and box, which destroys the period hardware that historic-character compliance depends on. We don’t do that unless the original lock is genuinely beyond saving, and we’ll show you why before any cutting happens.

Full replacement when rekeying can’t work

If the lock body is cracked, the internal springs are broken, or someone already drilled the cylinder and damaged the mortise box, rekeying won’t hold. That’s a replacement. We’ll quote the full price in writing before work begins and tell you exactly what hardware we’re installing.

New deadbolts on period doors

Installing a new deadbolt on a 1910s-1940s door in Orange takes careful alignment with the original strike plate. If the door has sagged or the frame has shrunk from Santa Ana wind cycles, the new bolt won’t throw cleanly. We adjust the strike plate and shim the hinges as part of the installation, not as an add-on surprise.

Trusted Brands We Service in Orange

We’re factory-authorized to install and service Schlage, Kwikset, and Medeco hardware, plus higher-security lines like Mul-T-Lock and Abloy for Orange homeowners who want bump-resistant or restricted-key cylinders. Most Old Towne mortise conversions use a Schlage or Medeco cylinder insert that matches the vintage face size. For 1960s tract homes near Villa Park, Kwikset smart-key and Schlage B-series deadbolts are the common workhorses. We carry common parts in the van, so a standard Change Door Locks job in Orange doesn’t require a second trip.

Common Change Door Locks Problems We See in Orange Homes

• Deadbolts that worked all summer fail in October. Santa Ana wind events drop humidity fast, and the original wood door frames in Old Towne shrink and gap. The bolt no longer reaches the strike plate. We adjust the strike and extend the bolt throw instead of selling you a new lock.
• A big-box knob-and-deadbolt was forced onto a mortise-lock door. The original faceplate and box got cut away, which hurts historic-character compliance on a pre-war home. We can sometimes restore a period-appropriate mortise cylinder insert and repair the door.
• A rekey was attempted on a mortise lock with a worn cylinder body. The lock still won’t latch because the cylinder itself is shot or the insert is the wrong vintage size. We stock 1⅛” and 1¼” mortise cylinder formats for exactly this scenario in Old Towne.
• Rental turnover near Chapman creates key-control anxiety. You don’t know how many copies of the old key are floating around. A rekey gives you new keys and a controlled copy count, and it costs far less than replacing every lock on the property.
