Fast, Reliable Door Lock Repair Across Palo Alto
Door lock repair in Palo Alto usually costs between $95 and $240 for a standard knob or deadbolt fix, and most jobs are done the same day. We work throughout Palo Alto, from the tree-lined streets of Old Palo Alto to the ranch homes of Midtown, and we carry parts for the older mortise locks so common here. If your key won’t turn at all, a latch won’t retract, or your deadbolt has started binding, call us at (910) 714-4287. We will give you a written price before any work begins, and that price does not change when the tech arrives.
Why Dunmore Locksmith Is Palo Alto’s Preferred Door Lock Repair Company
Palo Alto door hardware is not like door hardware in other Bay Area cities. We see original mortise locks from the 1920s and 1930s nearly every week, often in homes where the owner wants to keep the historic brass faceplate but needs the internals rebuilt. Our techs know how to re-cylinder a 1938 Craftsman mortise body without butchering the door, and they know when a lock is genuinely beyond saving. That matters more here than in a city where every door takes a modern tubular latch.
Our reputation in Palo Alto is built on written prices and named technicians. You get the technician’s name and photo before the visit. The price goes in writing before a single screw comes out. Our 365-Day Done Right Promise is stamped on every job: if the repair fails, we return at no charge. No vague promises, no “satisfaction pledge” fine print. The Threshold Standard applies to every person we send to a Palo Alto home: background-checked, identity-verified, photo-badged, and dressed in a marked uniform.
We coordinate dispatch from the brand’s San Francisco Bay Area office, and our techs are normally in Palo Alto within 45 to 60 minutes for a scheduled repair. Phones are answered 24 hours a day by a live person, never an answering service or a chatbot. If you call at 2 a.m. because your deadbolt just seized, a real person picks up.
Door Knob Lock Repair in Palo Alto
Door Knob Lock Repair in Palo Alto typically runs $95 to $180, and most knob repairs take under an hour once we’re at the door. A knob lock that spins without engaging, fails to latch, or turns but won’t open the door is usually a worn spindle, a broken latch spring, or a misaligned strike plate. In older Palo Alto homes, we often find another culprit: original brass knobs with worn internal hubs that no longer grip the spindle. A quick lube job won’t fix that. The hub needs replacement or the knob body needs a rebuild.
The good news is that a worn knob on a 1930s Craftsman door in Palo Alto rarely means you need a whole new lockset. We can replace the internal hub and spindle, re-pin the cylinder to match your existing key, and keep the visible hardware exactly as it is. For standard modern knobs, we stock Schlage and Kwikset internals on the truck and can usually complete the repair the same visit.
When a Knob Repair Becomes a Replacement
Some knob locks are too far gone. If the knob body is cracked, the spindle channel is wallowed out, or the internal spring mechanism has shattered, replacing the knob is cheaper than rebuilding it. In that case, we can match the existing Schlage or Kwikset keyway, or re-pin a new knob to your current key, so you aren’t paying for new keys on top of the repair.
Knob Lock Repair vs. Door Alignment in Palo Alto
On older Palo Alto doors, the knob latch and the door alignment are often fighting each other. A latch that only catches sometimes is frequently a sagging door, not a broken lock. We check the reveal, the hinge screws, and the strike plate before we touch the internal mechanism. If the door has settled, we adjust the strike plate or re-hang the door rather than forcing the lock to work against a misaligned frame.
Broken Key Extractor in Palo Alto
Broken Key Extractor service in Palo Alto costs $85 to $150 when the key half is visible in the cylinder, and $125 to $220 if the break is deep inside the lock. A broken key is one of the most common emergency calls we get here, especially in older locks with worn cylinders that grip the key tighter than they should. The key snaps, the broken half stays in the keyway, and you either can’t get in or you can’t lock the door behind you.
We use a broken key extractor set, not drills, as the first tool on the job. If even a sliver of the key protrudes, a spiral extractor or a thin hook pick usually pulls it out in minutes. For keys snapped deep inside the cylinder, we may need to disassemble the lock enough to push the broken piece out from the back. On a standard knob or deadbolt, that is a 15-minute job. On an original Palo Alto mortise lock, it takes longer because the cylinder has to come out of the mortise body first.
Extraction Without Destroying the Cylinder
Our goal on every Palo Alto extraction call is to save the lock. Drilling destroys the cylinder and means a full replacement. Extraction preserves it. After removing the broken key, we test the cylinder for damage. A bent key fragment can nick the pin chambers, and on rare occasions the cylinder needs re-pinning before it will accept a key smoothly again. We will tell you if that is the case before we do the work.
What to Do Before We Arrive
Do not force the broken key further into the lock and do not insert a second key or a paperclip. Both push the broken piece deeper and turn a simple extraction into a disassembly. Leave the lock as it is and call us. We can usually be at a Palo Alto address within an hour for this kind of urgent repair.
Trusted Brands We Service in Palo Alto
We are factory-authorized to service Schlage, Kwikset, Medeco, and Yale hardware, and we stock common Schlage and Kwikset pins, spindles, latches, and cylinders on the truck so most Palo Alto repairs are one-visit jobs. For high-security cylinders on older homes, we install and service Medeco and Mul-T-Lock at the mortise lock level, preserving the original faceplate while upgrading the cylinder core to something that resists picking and bumping. If your Palo Alto home runs a Schlage Encode or Yale Assure smart lock, our techs handle the firmware and pairing problems as readily as the mechanical repair underneath.
Common Door Lock Repair Problems We See in Palo Alto Homes
- Worn mortise lock hubs and cams in Old Palo Alto and Crescent Park. Original mortise bodies from the 1920s through 1950s have brass hubs that wear oval after decades of use. The latch retracts weakly or does not retract at all, even though the key turns. Lubricating the lock treats the symptom; rebuilding the hub treats the lock.
- Marine-layer humidity binding on north-facing and west-facing doors. Palo Alto’s Bay-side moisture swells original unfinished wood and oxidizes brass and steel hardware faster than in drier inland cities like Los Altos Hills. Deadbolts that threw smoothly in September can bind come February. We replace steel internals with satin nickel or stainless where the corrosion pattern calls for it.
- Smart lock retrofits that don’t fit the original door geometry. We see many smart locks bolted onto doors with non-standard backsets or mortise preps. The keypad plate sits crooked, the bolt drags, and the motor strains until it burns out. The lock is not defective. The mounting is. We rework the prep and align the bolt so the smart lock actually works.
- Student and postdoc rental turnover along El Camino Real and streets near Stanford’s campus. Landlords and property managers re-key in bulk around Stanford’s academic calendar, which means June and August are when we see the most worn latches, loose knobs, and seized deadbolts on rental-grade hardware. Lock repair volume spikes in those six weeks every year.
Pricing for Door Lock Repair in Palo Alto, CA
Our typical door lock repair in Palo Alto runs $95 to $240 depending on what is actually wrong. Here are the line-item ranges we quote most often: knob lock repair from $95 to $180, deadbolt repair from $110 to $220, broken key extraction from $85 to $150 for a visible break, and mortise lock rebuilding from $180 to $340 depending on the internal condition and cylinder type. A rekey, which is related but separate, typically runs $20 to $35 per cylinder on a standard Schlage or Kwikset lock. High-security Medeco or Mul-T-Lock cylinders cost more because the cylinders themselves are more expensive, not because the labor is marked up.
We give the full written price on the phone before we dispatch anyone. That is the price on the invoice. There is no call-out surcharge added on arrival and no bait-pricing where a low number suddenly becomes something else at your door. Call (910) 714-4287 and we will quote the job honestly, including the range, so you know what to expect before the tech arrives.

FAQs About Door Lock Repair in Palo Alto
Yes, we can rekey an original mortise lock in your Old Palo Alto bungalow in most cases. The mortise body itself rarely needs replacement just to rekey; we pull the cylinder, swap the pins to match a new or existing key, and put it back into the original body. What sometimes needs replacement is the internal hub or cam if those parts have worn after 80-plus years of use, but the visible lock body and faceplate stay. Rekeying a mortise cylinder in Palo Alto typically runs $25 to $45 per cylinder. Call (910) 714-4287 and we can walk through what your specific lock needs, with a written quote before we schedule.
In Palo Alto it is usually both. Marine-layer humidity swells the original unfinished wood, and the door edge moves just enough that the deadbolt no longer lines up with the strike. The lock mechanism itself may still be fine. We check the bolt throw, the strike plate alignment, and the hinge screws to see which part has moved. Often the fix is hand-fitting a satin-nickel strike plate to the warped door edge, not replacing the deadbolt. We will tell you which it is before we charge for any repair.
Your smart lock has lost its orientation calibration. Replacing the cylinder changes the internal tailpiece position slightly, and the lock’s firmware now thinks the bolt is in the wrong state. In many Palo Alto smart lock callouts, the mechanical lock works fine and the issue is a Bluetooth pairing or Z-Wave inclusion problem after the cylinder swap. The fix is usually a factory reset of the lock plus a fresh pairing, not a new lock. Bring the original install code with you if you have it. If you don’t, we can still recover most locks from the keypad admin menu.
No, drilling is the last resort on a Midtown Palo Alto lockout. Most knob locks and deadbolts on Midtown ranch homes open with picks, bump-resistant techniques, or airbag and bypass tools within a few minutes, none of which damage the lock. Drilling is only used when the cylinder is severely corroded, the lock has been tampered with, or the keyway is too worn to pick. Even then, we tell you the price for the drill-and-replace before we start.
Because Palo Alto’s rental market runs on Stanford’s academic calendar. The dense student and postdoc rental corridor along El Camino Real and streets bordering campus turns over in mid-June and late August, and landlords schedule bulk re-keys, lock repairs, and lock changes during those two windows. It is the busiest time in a Palo Alto locksmith’s year. If you need non-urgent lock repair during those weeks, book a few days ahead. If it is urgent, call anyway; we keep emergency slots open and a live person answers at (910) 714-4287.
