Fast, Reliable Door Lock Repair Across San Rafael
A deadbolt that won’t throw or a sliding door latch that won’t catch is more than annoying. It’s a hole in your home’s security. Door lock repair in San Rafael typically runs $85 – $225 depending on the lock type and what’s actually wrong, and most jobs are finished the same day we arrive. We’re Preston Locksmith & Security, and we’ve been fixing locks across San Rafael since 2008. Call (409) 405-4485 and you’ll get a written price before we dispatch anyone, a live arrival time you can track, and a technician in uniform who shows up with a photo ID.
We know San Rafael’s neighborhoods: the hillside homes off Lincoln Avenue, the older bungalows near downtown, the mid-century tracts in Terra Linda and Santa Venetia. Different houses, different lock problems. Our Door Lock Repair team carries the hardware and replacement parts for the brands most common in Marin County, so we’re not running to a supply house mid-job.
Why Preston Locksmith & Security Is San Rafael’s Preferred Door Lock Repair Company
We’re not a call center that subcontracts to whoever’s available. Kevin Yoon runs our San Rafael operation, and every technician who knocks on a door in this city is background-checked, uniformed, and is the same person whose name and photo you received before we dispatched them. That matters when you’re letting someone into your home to work on the lock that protects it.
Our San Rafael customers tell us the same thing: the price we quoted on the phone is the price on the invoice. That’s not a marketing line. It’s The Relay Visibility Guarantee, and it means a written price before work starts, live tracking of our arrival time, before-and-after photos of every repair, and a written 365-Day Done Right Promise on every job. If the repair fails within a year, we come back and make it right at no charge. That’s not a policy we quote to close a sale. It’s stamped on every work order.
We answer our phones with a live person 24/7. No voicemail queue, no “leave a message and we’ll call you back.” When you call at 2 a.m. because a deadbolt has seized and the door won’t close, you’ll talk to someone who can dispatch a technician to your location in San Rafael right then.
Sliding Door Lock Repair in San Rafael
Sliding door lock repair in San Rafael usually means one of three things: a patio door latch that won’t grab the strike plate, a locking mechanism that’s stuck in the locked position, or a handle that spins free without engaging the lock at all. The fog that rolls through the San Rafael hills doesn’t just make the grass wet. It gets into door frames and alarmingly often it’s the sliding doors in older San Rafael homes that take the worst of it. Wood swells, aluminum tracks oxidize, and the latch that worked fine in October suddenly won’t catch in February. Most of these repairs run $95 – $185 for a standard sliding patio door, and we’ll tell you before anything is ordered whether we can repair the existing hardware or need to replace the latch assembly.
What We Actually Do
We remove the handle set and mortise latch, clean out the track and the latch pocket, check the door’s alignment on its rollers, and then re-install or replace the latch so it seats cleanly. If the door itself has sagged, which is common on older San Rafael decks and patios, we adjust the rollers rather than grinding the strike plate. A properly adjusted door locks with a soft click, not a hard slam.
What It Costs
Expect $95 – $185 for sliding door lock repair on a standard patio door in San Rafael. If you have a multi-point lock or a custom Andersen or Marvin sliding door, the range can stretch to $220 – $340 because those parts cost more and the alignment work takes longer. No call-out surcharge on top of the quoted price, no “we didn’t realize it was that kind of lock” upcharge when we arrive. The price we give you on the phone is the price you pay.
Call (409) 405-4485 for an exact quote on your sliding door. We’ll ask you a few questions about the door brand and what’s happening, and you’ll get a written price before we dispatch anyone to San Rafael.
Deadbolt Repair in San Rafael
Deadbolt repair in San Rafael covers a few common failures: a bolt that won’t fully extend into the strike plate, a thumb turn that spins without moving the bolt, or a key that turns but only partially retracts the deadbolt. San Rafael’s older homes, especially the mid-century construction in Terra Linda and Santa Venetia, have a specific problem: the exterior doors are thinner than modern building standards call for. A Grade 1 deadbolt needs full door thickness to sit correctly, and on these doors the bolt often doesn’t have enough travel to seat fully into the frame. That’s why we carry reinforcement plates and longer mounting screws as standard on our San Rafael trucks. Most deadbolt repairs run $85 – $185 for labor, and if the deadbolt itself is worn past repair, a new Schlage or Kwikset deadbolt installed typically runs $150 – $250 including the hardware.
When Repair Beats Replacement
If the deadbolt is binding but the bolt moves, the fix is usually the strike plate rather than the lock itself. The plate has shifted a millimeter or two, or the wood around it has swelled, and suddenly the bolt doesn’t line up. We adjust the plate, and if the frame has swollen we shim it and reset the screws. That’s a $85 – $125 repair on most San Rafael doors.
When the Lock Body Is Done
If the springs inside the deadbolt have worn out, the bolt won’t stay thrown even after you’ve turned it. You can see it creep back into the door. That’s not a strike plate issue. The lock body is spent, and on most residential hardware the fix is a new deadbolt. We install Schlage, Kwikset, Medeco, and Yale deadbolts, and we’ll give you the exact installed price on the phone before we dispatch. For high-security options like Medeco or Mul-T-Lock, expect $280 – $400 installed in San Rafael, and we’ll show you the written price before we touch a screwdriver.
Trusted Brands We Service in San Rafael
We work on the hardware that’s actually on the doors in San Rafael. That means plenty of Schlage and Kwikset on the residential side, some Yale on older entry sets, and Medeco on the commercial storefronts along Fourth Street and on upscale homes in the Dominican neighborhood. We stock replacement cylinders, tail pieces, strike plates, and mounting hardware for these brands in our vehicles, so when we diagnose a failed Kwikset deadbolt we usually have the part on the truck. That’s the difference between “we’ll have to come back” and done today.
Common Door Lock Repair Problems We See in San Rafael Homes
- Fog-swollen doors misaligning deadbolts: The damp air that rolls through San Rafael from the bay and the nearby wetlands gets into wood door frames. Casings swell, and a deadbolt that worked fine all summer suddenly won’t throw because the strike plate is now sitting a quarter-inch off. We realign the plate, and often add a hardened steel reinforcement plate so it doesn’t happen again.
- Original mid-century mortise locks with dead springs: Homes built in the 1950s and 1960s in neighborhoods like Rafael Meadows and Sun Valley often still have their original mortise lock bodies. The exterior cylinder looks fine, but inside the lock body the springs have gone dead. You turn the key and nothing engages. The honest fix is replacing the mortise body, not lubricating it and hoping.
- Sliding door latches that only catch on the third try: San Rafael’s older patio doors sit on rollers that wear unevenly on wooden decks. The door sags, the latch misses the strike plate, and you’re standing there jiggling the handle. We adjust the rollers and realign the latch. It’s usually a repair, not a replacement.
- Door handles with worn spindles or stripped screws: Interior and exterior passage locks take abuse, especially in homes with kids. A handle that droops or spins likely has a worn spindle or a stripped set screw. We replace the internal components, not the whole door. Most of these jobs are under $125.

FAQs About Door Lock Repair in San Rafael
Yes, and this is one of the most common repairs we make in San Rafael. The deadbolt usually isn’t fully extending because the strike plate has shifted, the door has sagged or swelled with damp fog, or the bolt is binding inside the lock body. We diagnose it on site, show you what’s actually wrong, and in most cases the repair is $85 – $185. If the lock body itself has failed, we’ll quote you a replacement price in writing before touching anything. Call (409) 405-4485 for an exact price on your specific door.
Generally yes, by a small margin. Sliding door repair in San Rafael typically runs $95 – $185 versus $85 – $185 for a deadbolt, because sliding door latches require more alignment work and often roller adjustments. The materials can also cost more on multi-point locking systems. The price you’re quoted on the phone for either job is the price you pay. We don’t add a premium once we see the door.
Before we dispatch anyone to your home in San Rafael, we send you the technician’s name, photo, and vehicle description. When they arrive, they’ll be in a Preston uniform and carrying a photo ID you can ask to see. This is part of The Relay Visibility Guarantee. You never get an anonymous contractor in an unmarked van. You know who’s coming before they knock, and their live arrival time is trackable on your phone.
In most San Rafael homes, yes. A sticking Kwikset lock is usually a strike plate misalignment, dirt or corrosion inside the cylinder, or a swollen door frame. We clean and lubricate the cylinder, adjust the plate, and re-torque the mounting screws. Drilling is a last resort for a seized cylinder that won’t turn even with the correct key, and we’ll tell you before we do it. Most sticky Kwikset locks we see are fixed for $85 – $125 without needing replacement hardware.
On older San Rafael doors, especially mid-century homes in Terra Linda and Santa Venetia, the repair usually starts with the door itself. If you’d prefer to rekey rather than replace, we can handle that too once the hardware is working smoothly. We check the bolt’s alignment against the strike plate, and if the wood has swelled, we’ll shim or reset the plate, lubricate the bolt, and re-torque the mounting screws. In some cases we install a reinforcement plate with longer screws because the original builder-grade screws are too short for the thinner door slabs common in this era of San Rafael construction. The goal is a deadbolt that throws cleanly without needing replacement. Most of these repairs are $85 – $185, and the price is in writing before we start.
