Why Preston Locksmith & Security Is Cotati’s Preferred Door Lock Repair Company
Kevin Yoon founded Preston Locksmith & Security in 2008, and the way we run Cotati jobs comes straight from how Kevin would want a repair done at his own front door. Every Cotati customer gets The Relay Visibility Guarantee on paper: a written price before any work starts, a live arrival time you can track on your phone, before-and-after photos, and a written guarantee covering the repair for a full year. If it’s not done right, we make it right at no charge, and a failed repair earns a free second visit. Phones are answered 24/7 by a real person, never a voicemail tree.
We’re part of the Relay Home Co. family, and this location is independently owned and operated. That means the technician who shows up in Cotati is accountable to the person whose name is on the guarantee, not a distant call center. We keep parts for Schlage, Kwikset, Medeco, and Yale hardware stocked in our service vehicles, so most Cotati repairs finish in a single visit. When a technician arrives, they’re in uniform, they carry ID, and they’ll walk you through exactly what needs to happen before any tool leaves the bag.
Broken Key Extractor in Cotati
A Door Lock Repair call that starts with a snapped key is common in Cotati, particularly in the older ranch homes near downtown where original mortise hardware has outlived two or three generations of keys. Broken key extraction in Cotati typically runs $85 – $150, depending on how deep the break is and whether the cylinder has internal damage from years of slow wear. We use a broken key extractor tool to pull the snapped piece out without drilling, and we always confirm the cylinder still turns clean before calling the job done. If the mortise internals are gummed up, we rebuild those first so the repair holds.
Non-Destructive Entry First
Some Cotati locksmith calls end with a drilled-out lock that never needed to be drilled. We don’t do that. A broken key extractor, a pick gun, or a bypass tool gets most Cotati doors open without destroying the hardware. That matters in a town where 1960s-era mortise locks aren’t sitting on a shelf at the local hardware store anymore.
When The Key Breaks Off Inside
In Cotati’s older homes, keys usually snap because the pin and tumbler inside the cylinder have been slowly binding for months or years. The key finally gives. We extract the broken piece, clean and lubricate the cylinder, and test the lock with a new key before we leave. If the cylinder is too far gone, we quote a replacement before doing the work, never after.
Sliding Door Lock Repair in Cotati
Sliding glass door lock repair in Cotati typically costs $110 – $220, and the work usually takes an hour or less once we’re on site. Cotati homes built from the 1970s onward commonly have patio sliders with rim locks or mortise-style sliding door latches that seize after years of Petaluma Valley dust and seasonal moisture working into the track and mechanism. A sliding door that won’t latch is a security problem, not just a nuisance: that door is often the least visible entry point on a Cotati home.
What The Repair Actually Involves
We start by checking whether the lock body is misaligned with the strike, which is the most common failure in Cotati’s settling ranch homes on clay soil. Then we inspect the latch, the thumb turn, and the track. If the hardware is just gummed up and misaligned, we realign and service the existing lock for the quoted price. If the lock body is cracked or the latch is worn past function, we’ll show you the failed part and quote a replacement before touching it.
Replacing Worn Sliding Door Hardware
When a Cotati sliding door needs new hardware, we carry replacement locks that fit standard patio door cutouts and can match the existing finish in most cases. A worn sliding door lock that finally stopped latching is the top reason Cotati renters and homeowners call us about patio security. We’ll also check the anti-lift blocks and secondary screws while we’re there, because a sliding door lock only works if the door can’t be lifted off its track.
Trusted Brands We Service in Cotati
We service and repair Schlage, Kwikset, Medeco, and Yale hardware across Cotati, from the deadbolts on Old Redwood Highway storefronts to the Kwikset knobsets in subdivision homes near Helen Putnam Regional Park. Our service vehicles carry common cylinders, springs, tailpieces, and mortise cassette replacements for these brands, which means most Cotati repairs don’t wait on a parts order. If you have a Baldwin or Sargent lock, we service those too. If you’re not sure what brand is on your door, call (409) 405-4485 and describe what you see; we’ll identify it from your description and arrive with the right parts.
Common Door Lock Repair Problems We See in Cotati Homes
- Re-drilled mortise lock pockets in 1950s – 60s ranch homes. Decades of hardware swaps leave original mortise pockets chewed out. What looks like a deadbolt repair often becomes a mortise lock rebuild, and we quote that honestly before starting.
- Stiff or jammed deadbolts near downtown Cotati. Older single-story homes near the downtown corridor deal with moisture and seasonal temperature swings that make unmaintained deadbolts bind. A bolt that fights the key is a sign the cylinder or tailpiece is failing.
- Sliding patio doors that won’t latch on newer two-story builds. Cotati’s newer construction on the east side of town often has patio sliders with lightweight rim locks. When the latch stops engaging, homeowners go weeks assuming the lock is fine because the handle still moves.
- Lost or duplicated keys after a tenant turnover. Cotati has a steady rental market near Sonoma State University. Landlords call us for rekeys and lock repairs between tenants, and we quote per-cylinder pricing in writing before the job is scheduled.
Pricing for Door Lock Repair in Cotati, CA

Rekeying a standard lock to a new key runs $25 – $45 per cylinder, and if you have a few locks, that adds up fast but stays predictable.

FAQs About Door Lock Repair in Cotati
Yes, in most cases. We use a broken key extractor to pull the snapped key from the cylinder, then test whether the internal pins and tumbler still function. If the cylinder turns clean, the lock stays in place and you save the cost of a replacement. Call (409) 405-4485 and describe your lock; we’ll tell you over the phone what’s likely involved.
Your technician arrives in a marked vehicle, wearing a Preston Locksmith & Security uniform, and carries company ID. When you book, you get a live arrival time you can track, so you’ll know who’s coming and when they’ll be at your Cotati door before anyone knocks. We’ll also confirm the job details and price with you before any work begins.
Almost always yes. Rekeying in Cotati runs $25 – $45 per cylinder, which means you can reset every lock on a rental for less than the cost of one good-quality replacement deadbolt. The existing hardware on a Cotati rental is often original 1960s mortise hardware that’s better built than what’s sold at a big box store today, so rekeying preserves that value. Call (409) 405-4485 and we’ll quote a flat per-cylinder price for the whole property before you agree to anything.
We assess whether the lock body is misaligned, whether the latch or thumb turn is worn, and whether the door itself has shifted on its track. In Cotati’s ranch homes, clay soil movement often knocks the door slightly out of alignment, which prevents the latch from seating. We realign and service the existing hardware when possible, and quote a replacement only when the lock is genuinely exhausted.
No. We use non-destructive entry methods first: broken key extraction, picking, or bypass tools. Drilling is a last resort, and if we ever need to drill, you’ll see why before we do it. Drilling a 1960s-era mortise lock in Cotati destroys hardware that’s hard to replace, and a real locksmith should exhaust every other option first.
