Fast, Reliable Door Lock Repair Across Burlingame
Door lock repair in Burlingame usually costs between $85 and $240 for common fixes like a seized cylinder, broken key extraction, or a misaligned latch. Most jobs are completed the same day, and our team answers the phone around the clock at (910) 714-4287. We know Burlingame’s older homes and apartment buildings better than a generalist ever could, because the lock problems here are not the same as they are ten miles inland.
If you live in the Easton Addition, near Burlingame Avenue, or up in the Burlingame Hills, you are probably dealing with hardware that was installed before your parents were born. That is not a reason to replace a solid door. It is a reason to call someone who understands mortise lock repair, bay-salt corrosion, and non-standard escutcheons.

That is the Threshold Standard, and it applies on every single call, whether it is 2 p.m. on a Tuesday or 3 a.m. on a Sunday.
Our response time to Burlingame neighborhoods is fast because dispatch is coordinated from the San Francisco Bay Area office, and crews are stationed to serve the Peninsula directly.

Door Knob Lock Repair in Burlingame
Door Knob Lock Repair in Burlingame most often means freeing a seized or stiff knob mechanism, tightening a loose rose plate, or replacing a worn latch assembly that no longer retracts cleanly. Given the age of many door prep jobs here, the knob is often mounted to a mortise lockset rather than a modern cylindrical bore, which means the repair has to be adapted, not swapped. A standard knob lock repair in Burlingame typically runs $85 to $165, depending on the hardware and whether the latch or cylinder needs replacement.
Tightening and alignment work
A loose interior knob or a sagging latch on a 1930s door usually means the mounting screws have backed out of the threaded rose or the strike plate has drifted. We re-secure the hardware, shim or re-align the strike, and verify the latch throws cleanly before we leave. This is the least expensive repair we do, and it is often the one that keeps a door from failing again weeks later.
Replacing worn latch or cylinder components
When the knob turns but the latch no longer retracts, the internal spindle or cam is worn. On older Burlingame hardware, replacing these components usually costs more than a big-box swap because the parts are sourced to match the original prep, not the other way around. We carry a range of mortise latch assemblies and adapters, so we can usually repair the door without cutting into it.
Broken Key Extractor in Burlingame
Broken key extractor service in Burlingame is one of our most common calls, and the marine layer is a major reason why. Salt-laden moisture from the bay works into brass and zinc-alloy cylinders, accelerating corrosion. The pins bind, you apply more pressure, and the key snaps off in the cylinder. We use non-destructive extraction tools designed for standard and high-security keyways, and the repair typically runs $95 to $180, including the extraction and a replacement key if the original is too damaged to duplicate.
Non-destructive extraction
The goal is always to pull the broken piece out without drilling the cylinder. We use spiral, hook, and barbed extractors matched to the keyway profile. In most cases on Kwikset and Schlage cylinders, the extraction takes under thirty minutes. The cylinder is then cleaned, lubricated, and tested with a fresh key.
When the cylinder is already too far gone
If the cylinder was severely corroded before the key broke, the internal pins may be damaged enough that the cylinder should be replaced rather than repaired. We will tell you that before we start. The repair is still usually done the same day, and the price is in writing before any work begins.
Trusted Brands We Service in Burlingame
Our Door Lock Repair team is factory-authorized on the hardware Burlingame homeowners actually have: Schlage, Kwikset, Medeco, and Abloy, among others. We keep a working inventory of mortise cylinders, latch assemblies, escutcheons, and strike plates in our service vehicles, because a 1930s Sargent lock in the Easton Addition does not accept the same cylinder as a 2005 Kwikset deadbolt near Broadway. That inventory means we can usually complete the repair on the first visit. When a specific trim or finish has to be ordered, we say so upfront, in writing, with a timeframe that does not change later.
Common Door Lock Repair Problems We See in Burlingame Homes
- Seized mortise cylinders from bay-salt corrosion. Homes within a mile of the bay get daily marine-layer exposure, and original brass cylinders on 1920s and 1930s Craftsman doors bind and snap keys. We free the pin stack, clean the corrosion, and often adapt a new cylinder to the old escutcheon instead of drilling.
- Restricted key loss in multi-tenant buildings. Burlingame’s condo and apartment buildings often use restricted keyways where a lost key means the common entry door has to be rekeyed, not just recut. We coordinate with the property manager so a single duplicated key does not compromise building-wide key control.
- Smart lock retrofits on thick-stile mortise preps. Frequent-flyer homeowners in the Burlingame Hills want remote access without gutting a century-old door. A misaligned smart lock bolt on a non-standard mortise prep is a common failure. We adapt the prep or recommend hardware that actually fits.
- Deadbolts that were never rekeyed. Mid-century ranch homes above El Camino Real often still have the original deadbolt from the 1950s or 1960s, and the keys have passed through a dozen hands. We rekey these cylinders so unknown old keys no longer work.

Beyond Door Lock Repair in Burlingame
While Door Lock Repair is the call we answer most often in Burlingame, it is rarely the whole job. A seized cylinder on an Easton Addition bungalow usually points to a lock that should have been rekeyed a decade ago. A broken key in a condo common door often means the building should talk to us about restricted key control. Dunmore Locksmith handles the full range: rekeying, lock changes, deadbolt installation, high-security cylinder work, and access control. When we repair one lock on a home, we always check the others and tell you if another cylinder is about to fail. That is not an upsell; it is how a knowledgeable neighbor treats a Burlingame door.

FAQs About Door Lock Repair in Burlingame
Yes. Restricted keyways are designed so that a lost key does not automatically force a full master-system rekey, but the common door cylinder usually does have to be rekeyed to exclude the lost key from the system. We coordinate with your property manager, confirm the keyway and system documentation, and rekey the affected cylinder so the lost key no longer operates it. This typically runs $95 to $180 per cylinder in Burlingame, and we provide written documentation for the building. Call (910) 714-4287 and we will walk you through it.
No. In most cases on original Burlingame mortise locks, the broken key can be extracted non-destructively and the seized cylinder freed without drilling. The challenge on many Easton Addition doors is the antique escutcheon, which is often a non-standard size. We stock mortise cylinder adapters specific to these older preps, so we can fit a new cylinder without cutting into the door or replacing the original trim. This repair pair, extraction plus cylinder adaptation, typically runs $140 to $240. If the mortise body itself is damaged, we will tell you before any work starts.
Burlingame sits on the western edge of San Francisco Bay, and the daily marine layer carries salt-laden moisture directly into exterior lock mechanisms. That salt accelerates corrosion of brass and zinc-alloy components significantly faster than in San Mateo, Belmont, or other Peninsula cities a few miles from the water. The result is seized cylinders, stiff pins, and broken keys at a higher rate. We clean and lubricate the cylinder during the repair, which slows the recurrence, but bayfront locks will always need more frequent maintenance than inland ones.
Usually yes, but it is not a simple screw-on job. Thick-stile mortise preps from the 1920s through 1940s were not built for modern cylindrical smart lock hardware. We can often install a smart lock or keypad using an adapter plate that preserves the original mortise prep, or we can recommend a smart mortise cylinder that fits the existing lock body. The key is getting the bolt alignment right so the door latches cleanly every time. A retrofitted smart lock install in Burlingame typically starts at $180, with the exact price depending on the prep and hardware. Call (910) 714-4287 and we will assess your door specifically.
Rekeying is almost always the better first step, and it costs less. Rekeying a standard deadbolt in Burlingame runs $65 to $120, and it makes all previous keys useless. Replace the hardware only if the deadbolt itself is failing: a loose bolt, a stripped tailpiece, or a cylinder that no longer turns smoothly even after cleaning. On a mid-century ranch home above El Camino Real, the original deadbolt is often serviceable and worth keeping. We will tell you honestly which applies to your door, and the price is in writing before work starts.
