Locksmith in Claremont, CA
Finding a locksmith in Claremont means working with a city that has two very different sets of doors: century-old mortise locksets on craftsman bungalows near the Village, and mid-century deadbolts on ranch homes further south and east. The work here is shaped by Santa Ana winds that dry out wooden frames every fall and by the seven Claremont Colleges, which compress a huge amount of institutional rekeying into a few weeks each late summer. Dunmore Locksmith answers the phone with a live person around the clock and sends a named, photo-badged technician to your door. Call (910) 714-4287 for a written quote before any work begins.
Why Claremont Homes Are Different
Claremont’s housing stock runs old in the historic core. Many homes near the Village were built between 1910 and 1945, and a good number still have their original mortise locksets. Those are not hardware-store swaps. They need legacy parts, careful fitting, and a technician who knows the difference between a worn spindle and a broken spring inside the case. A quick replace-it-with-a-modern-deadbolt answer strips character out of a home and often leaves a badly patched door edge behind. We prefer to rebuild the original lock when it makes sense, and we stock common mortise components so the job does not stretch into a multi-week parts hunt.
The climate here does real work on doors. Claremont sits at the base of the San Gabriel Mountains, exposed to the same dry Santa Ana winds that hit the foothill cities hardest each fall. When humidity drops into single digits for days, wooden door frames shrink. Deadbolts that lined up in July suddenly bind against the strike plate in October. This is not a broken lock; it is a gap that appeared overnight. We see a predictable wave of these calls every autumn, and the fix is usually a strike plate adjustment or a slight re-mortise of the frame, not a new lock.
Summer adds another layer. Inland temperatures here regularly pass 100°F, which bakes the lubricant out of exterior lock cylinders and hardens rubber weatherstripping until latches drag. A lock that feels gritty in August often just needs a proper clean and a graphite or dry-film lubricant, not replacement. Knowing which problem you have before anyone quotes a price is the whole reason we inspect first and write the number down second.
Our Main Claremont Services
Claremont homeowners call most often about two situations: a lock that has stopped working properly on an older home, and a genuine security concern that calls for changing or rekeying locks. Each service has its own Claremont page with detail on pricing and process.
Residential Locksmith in Claremont
Most residential work in Claremont falls into three buckets: rekeying after a home sale or change in housemates, repairing aging hardware, and upgrading weak deadbolts on mid-century ranch doors. The historic homes near the Village often have older mortise bodies that can be rekeyed or repaired without replacing the whole lock, which preserves the original hardware. Our technicians arrive in a marked uniform, show a photo ID badge at the door, and put the full price in writing before any work starts. Read the full breakdown on our Residential Locksmith in Claremont page.

Door Lock Repair in Claremont
Door lock repair in Claremont often comes down to seasonal alignment issues. A deadbolt that will not throw, a latch that sticks past its strike plate, a key that turns but will not retract the bolt. In the fall, dry Santa Ana conditions shrink frames and throw deadbolts out of line; in high summer, baked-out lubricant makes cylinders feel rough and heavy. These are repairable conditions, and the fix is usually measured in minutes, not hours. Every repair we complete is covered by the 365-Day Done Right Promise: if it fails within a year, we return at no charge. Details are on our Door Lock Repair in Claremont page.

Change Door Locks in Claremont
When you change door locks in Claremont, the first decision is whether to rekey the existing hardware or replace it outright. Rekeying is less expensive and keeps your original hardware, but if the lock is worn past smooth operation, new hardware is the better long-term call. Homes built before 1945 with original mortise locks can often be rekeyed in place by a technician who knows the old pinning systems. If you’ve lost keys or have a new family member moving in, changing the lock removes any question about who has copies. See the full comparison and pricing on our Change Door Locks in Claremont page.

Commercial Locksmith in Claremont
Commercial work in Claremont is dominated by the Claremont Colleges ecosystem: seven institutions, dense master-key hierarchies, and a rush of rekeying and access-control changes every August and September when dormitories, faculty offices, and administrative buildings turn over simultaneously. That institutional rhythm makes this market different from any neighboring city. We work on master-key planning, electronic access control, and high-security cylinders for businesses across the city. Each job begins with a written scope and flat per-lock pricing. Learn more on our Commercial Locksmith in Claremont page.

Pricing for Locksmith in Claremont, CA
What a locksmith job costs in Claremont depends on the type of lock, the condition of the door, and whether we’re rekeying or replacing. These are the ranges we quote most often, always in writing before any work starts:
| Service | Typical range in Claremont |
|---|---|
| Rekey a standard knob lock | $40 – $80 per cylinder |
| Rekey a deadbolt | $50 – $90 per cylinder |
| Change one standard lock | $95 – $175 including hardware |
| Change one deadbolt | $110 – $200 including hardware |
| Repair a sticking or misaligned deadbolt | $75 – $150 depending on frame work |
| Mortise lock repair on a pre-1945 home | $130 – $280 depending on internal condition |
| Lockout service | $65 – $125 depending on time of day |
| Master-key system consultation | Quoted by written scope |
Mortise locks on older Claremont homes tend to push repairs higher because the internal components are no longer standard and take longer to fit. Commercial work is quoted per lock with a written scope, never an hourly estimate that can drift. The price we write before the work is the price on the invoice, every time.
