We carry hardware that matches local door types, so the lock we install fits the door you actually have, not whatever happens to be on the truck.
Why Dunmore Locksmith Is Palo Alto’s Preferred Change Door Locks Company
Dunmore Locksmith operates under the Threshold Group umbrella, serving Palo Alto customers since 2007 with a standard most local locksmiths don’t meet: every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. When the technician rings your bell, you already know exactly who should be standing there. That matters on a quiet Crescent Park street at 9 p.m.
Our Palo Alto customers consistently mention two things in reviews: the technician arrived when promised and the price on the invoice matched the quote. We don’t play the bait-pricing game that plagues this trade. The price goes in writing before work starts, every time. If a repair fails within 365 days, we return at no charge under our Done Right Promise. That’s not marketing language. It’s stamped on every written guarantee we hand a Palo Alto homeowner.
We also answer the phone with a live person 24 hours a day, 365 days a year. No voicemail tree, no chatbot, no answering service that promises a callback. If you’re locked out of a Midtown ranch at 2 a.m., a real human answers. Perry Osgood, who leads our team, set that standard because he knows a lock emergency doesn’t wait for business hours.
Door Lock Installation in Palo Alto
Door Lock Installation in Palo Alto means fitting a new deadbolt, knob lock, or handle set to an existing door, which in this city often involves preserving the character of older doors while upgrading the security cylinder inside them. We regularly install Grade 1 deadbolts on Midtown ranch homes, replace worn entry sets on condos near University Avenue, and retrofit 1920s mortise lock bodies in Old Palo Alto with modern high-security cylinders. A standard deadbolt installation in Palo Alto runs $110 – $190 per lock; a complete entry handle set replacement typically falls between $160 and $240 depending on hardware grade.
Working With Your Existing Door
Palo Alto homes built before 1960 often have doors that aren’t pre-drilled for modern deadbolt backset measurements. We carry adjustable latches, wrap plates, and mortise-specific hardware so we can install a secure lock without butchering an original door. If the freeholder or HOA restricts changes to the door itself, we can swap the cylinder only and leave the visible hardware untouched.
Smart Lock Installations
Palo Alto has a higher concentration of smart locks than most comparable cities. We install and service August Pro, Schlage Encode, Yale Assure, and Nest x Yale hardware, including Bluetooth and Z-Wave pairing, firmware troubleshooting, and access-log setup. If your lock won’t stay paired with HomeKit or Google Home, we can usually resolve it on site without calling the manufacturer.
Patio Door Lock Change in Palo Alto
Patio Door Lock Change in Palo Alto typically involves replacing or rekeying the mortise-style lock bodies and sliding door hardware on the glass doors that open to backyard decks and side yards. On Crescent Park and Old Palo Alto properties, these doors often sit on north- and west-facing elevations where marine-layer humidity accelerates oxidation of brass and steel hardware. We swap tired pin-and-tumbler cylinders on sliding doors for satin-nickel or stainless assemblies that hold up better in that exposure. A patio door lock change in Palo Alto generally runs $95 – $160 per door.
Sliding Door Locks That Actually Align
Palo Alto’s older homes settle. Sliding doors drift out of alignment, and the cheap surface-mounted locks that came with the door stop catching. We carry adjustable patio locks and foot bolts that compensate for a door that no longer sits square in its track. It’s a small fix that makes a real difference in how the door feels, and it costs under $150 in most cases.
Keeping Exterior Exit Paths Code-Compliant
Palo Alto building code requires egress doors to open from the inside without a key. If your patio door has a double-cylinder deadbolt that requires a key on the inside, it may not pass inspection when you sell. We can swap it for a single-cylinder deadbolt or an interior thumb-turn that keeps the outside keyed but allows one-motion exit from inside. Most Palo Alto homeowners change these out during pre-sale repairs or after a home inspection flags it.
Trusted Brands We Service in Palo Alto
We’re factory-authorized to install and service Kwikset, Medeco, Yale, and Baldwin hardware, and we carry a local parts inventory for Palo Alto’s most common door types. You don’t wait a week for a special order when your Baldwin entry set gives out. The team also works extensively with Medeco high-security cylinders on multi-tenant properties where restricted key duplication matters. For a Midtown home with standard Schlage or Kwikset hardware, we can complete the job in a single visit.
Common Change Door Locks Problems We See in Palo Alto Homes
- Copied keys on multi-tenant entries. A resident duplicates a building key at a hardware kiosk, and suddenly there are keys floating around that nobody can account for. We re-key the entry cylinder and issue controlled copies to current residents, restoring key control.
- Marine-layer binding on north- and west-facing doors. Palo Alto’s Bay-side humidity causes brass and steel locks on older unfinished wood doors to oxidize and bind. The deadbolt won’t retract smoothly, and the key feels like it’s fighting you. We swap in satin-nickel or stainless internals and lubricate the assembly.
- Mortise lock bodies owners don’t want replaced. Old Palo Alto and Crescent Park homeowners often want their original 1920s – 1950s mortise lock bodies preserved for historic aesthetics. We keep the body, replace the cylinder inside with a high-security one, and the door looks exactly the same.
- Smart locks that drop off the network. We see Bluetooth and Z-Wave pairing failures on almost every call involving a Palo Alto smart lock, often after a router change or firmware update. Most of these we fix by re-pairing and updating the lock’s firmware on site.

FAQs About Change Door Locks in Palo Alto
Yes. We can change the cylinder inside a condo entry door without replacing the door itself, which means the freeholder’s hardware stays intact but your keys stop working. This is standard practice in Palo Alto condo buildings along University Avenue and near downtown. Call (910) 714-4287 and we’ll quote the per-lock price before scheduling.
Marine-layer humidity from the Bay penetrates north- and west-facing doors during spring months, causing brass internals to swell and bind. We replace the cylinder with satin-nickel internals and lubricate the assembly, which typically resolves the seasonal binding. This is a common Old Palo Alto pattern we see every May and June.
Yes. The rental corridor along El Camino Real and streets bordering Stanford’s campus turns over units in bulk, and we handle multi-unit re-key jobs throughout June and late August. Landlords and management companies book us weeks ahead because those windows fill fast. Mention your building manager’s name and we’ll coordinate a bulk rate.
Yes. We remove the original cylinder from the mortise lock body, install a high-security cylinder from Medeco or a similar manufacturer, and the visible hardware stays exactly as it was. The door still opens with the period handle, but the key is now restricted and can’t be duplicated at a kiosk.
Yes. Bluetooth and Z-Wave pairing failures are common with August, Schlage Encode, and Yale Assure locks after router changes or firmware updates. We re-pair the lock, update its firmware, and verify the access log is recording correctly. This is a same-day fix for most Palo Alto homes. Call (910) 714-4287 for a free phone diagnosis.
