Fast, Reliable Door Lock Repair Across Sebastopol
A door lock that sticks, rattles, or flat-out won’t latch isn’t something to put off.

We serve the whole Sebastopol area with same-day scheduling, a written price before we send anyone out, and a live arrival time you can follow on your phone. Call (409) 405-4485 and a real person picks up, 24/7.
Why Preston Locksmith & Security Is Sebastopol’s Preferred Door Lock Repair Company
We’re the Door Lock Repair team that Sebastopol homeowners call when a front door won’t latch before work or a patio slider won’t lock before a trip. Kevin Yoon leads Preston Locksmith & Security, founded in 2008, with each location independently owned and operated under the Relay Home Co. family. What that means in practice: background-checked, uniformed techs, a phone answered by a live person, and a written guarantee stamped on every repair.
Sebastopol customers tell us the same thing again and again: they called us because someone else gave them an estimate that changed when the tech showed up. We don’t play that. The price we quote over the phone is the price on your invoice, and the full scope is agreed before a single tool leaves the bag. We coordinate dispatch and scheduling from our Bay Area office, with crews serving Sebastopol locally.
The 365-Day Done Right Promise is simple: if it’s not done right, we make it right, including a free second visit if the repair fails. Every job comes with before-and-after photos and a digital invoice with a pay link. You’ll know who is coming, what they look like, and when they’ll arrive.Deadbolt Repair in Sebastopol
Deadbolt Repair in Sebastopol usually means one of three things: a bolt that won’t fully throw into the strike plate, a thumbturn that spins without engaging the bolt, or a cylinder that grinds when you insert the key. On older Sebastopol homes, the deadbolt is frequently the original hardware from the 1950s or 60s, and the issue is a strike plate that drifted out of alignment when the door swelled. We quote the lock work and any strike adjustment together so you get one honest number before dispatch. Expect $95 to $240 for a typical deadbolt repair in Sebastopol, depending on the lock body condition and whether parts are needed. Replacement deadbolts run $180 to $340 including installation.
Sticking or Misaligned Deadbolt
When a deadbolt sticks, the bolt is often dragging against the strike plate edge. We realign the strike, shim it if needed, and lubricate the bolt throw so the key turns smoothly again. If the bolt itself is bent or the tailpiece is worn, we replace the internal components without changing your keys unless you want a rekey.
Deadbolt That Won’t Lock From the Inside
A thumbturn that spins freely usually means the tailpiece has broken or slipped out of the lock body. In Sebastopol homes with older Schlage and Kwikset deadbolts, this is a 20-to-40-minute repair. We open the lock body, re-seat or replace the tailpiece, and test the throw from both sides before we leave.
Patio Door Lock Repair in Sebastopol
Patio Door Lock Repair in Sebastopol focuses mostly on sliding glass doors and French doors that won’t secure. Sliding door locks jam when the track fills with dust and debris, or when the latch hook misaligns with the keeper. French door locks fail when the doors sag on the hinges and the lock no longer lines up with the strike. The repair typically involves cleaning and adjusting the latch mechanism, realigning the keeper or strike plate, and sometimes replacing the latch hook or handle set. Expect $120 to $320 for patio door lock repair in Sebastopol, with written confirmation before work begins.
Sliding Door Lock Not Catching
A sliding door lock that won’t catch is usually a keeper alignment problem, not a broken lock. We remove the keeper, reposition it so the latch hook engages fully, and clean the track so the door glides without dragging. If the latch itself is worn from years of use, we replace the hook assembly and adjust it on site.
French Door Handle That Won’t Lock
French doors often shift as the seasons change, which throws the handle-set out of line with the strike. We restore the alignment by adjusting the hinges or repositioning the strike, then lock and unlock the door a dozen times to make sure it engages from both sides. A written price comes before any adjustment begins.
Trusted Brands We Service in Sebastopol
We’re trained and equipped to service the hardware already installed in Sebastopol homes, from everyday Kwikset and Schlage deadbolts to Baldwin mortise locks and Medeco high-security cylinders. If your door has a Yale lock from the mid-century or a newer Baldwin handle set, we stock the common internal parts and can source the rest fast. No need to replace a classic mortise lock just because a chain shop doesn’t work on them. We service what’s already on your door, and when replacement genuinely makes more sense, we tell you straight and quote the full job before dispatch.
Common Door Lock Repair Problems We See in Sebastopol Homes
- Seasonal wood-door swell near downtown and Florence Avenue. Damp winters and hot, dry summers make wood doors expand and contract enough that strike plates drift. The deadbolt drags in fall and rattles in summer, and the fix usually includes an alignment correction alongside the lock work.
- Gummed-up mortise lock internals. Sebastopol’s damp-then-dry cycle pulls moisture into older mortise lock bodies, which thickens the factory grease into paste. The result is a key that turns hard or a bolt that won’t fully extend. Repair means pulling the lock body, cleaning the internals, and re-lubricating.
- Worn pin-and-tumbler cylinders on original 1950s and 60s doors. The pins wear down over decades until the key fails intermittently. We rekey these cylinders rather than replace the whole lock, which keeps the original hardware intact and costs less than full replacement.
- Patio slider locks jammed by track debris. Dust and grit from dry summers work into the latch and keeper. The door seems broken but the lock just needs cleaning and realignment, which we can usually do in one visit.
Here’s the thing locals already know: a lock that fails in Sebastopol is rarely just a lock problem. It’s a lock plus door condition, and a tech who only replaces the cylinder leaves you with a door that fails again in a few months. That’s exactly why we quote the lock work and any strike correction together, before anyone is dispatched.
We got a call from a homeowner near downtown Sebastopol whose 1950s front door had a Baldwin mortise lock that suddenly wouldn’t latch. The bolt was throwing, but the door had swelled with the season and the strike was misaligned. Our tech started with non-destructive entry to get them back inside, then pulled the mortise lock body, cleaned and lubricated the internals, and adjusted the strike plate so the deadbolt engaged smoothly again. We also rekeyed the cylinder at the same visit so the old keys stopped working and the family had a single working key for the door.

FAQs About Door Lock Repair in Sebastopol
It’s usually both. In Sebastopol, wood doors near the downtown core and Florence Avenue swell noticeably as fall humidity sets in, which pushes the strike plate out of line with the deadbolt.
