If you’re locked out on Old Redwood Highway or need a deadbolt replaced near Sonoma State, you want a locksmith who names a real price before getting in the van. That’s how we work in Cotati. Most residential calls here run between $65 and $240 depending on what the lock needs, and you’ll hear that range on the phone, in writing, before anyone is dispatched.

Why Preston Locksmith & Security Is Cotati’s Preferred Residential Locksmith Company
Cotati homeowners tend to ask the same three things before they let a locksmith touch their door: what’s this going to cost, who exactly is coming, and will I get a receipt I can actually read. We answer all three before the tech arrives. The price is in writing. The tech’s name and live arrival time show up on your phone through the Relay Visibility Guarantee, so you’re not staring out the window guessing which van is yours. And after the job, you get before-and-after photos plus a digital invoice with a pay link. No paper scribble, no “the bill got bigger when he saw the lock.”
Kevin Yoon, who leads Preston Locksmith & Security, built the whole operation around a very Cotati idea: this town is small enough that word travels, and a locksmith who pulls a bait-and-switch near La Plaza doesn’t stay busy for long. Our techs come in uniform and have been background-checked. Every repair carries the 365-Day Done Right Promise. If something isn’t done right, we come back and make it right. Free second visit if a repair fails. Written guarantee on every job, stamped on the invoice.
Locksmith Key Replacement in Cotati
Locksmith Key Replacement in Cotati usually means one of three things: you’ve lost the key entirely, the key snapped off in the cylinder, or the key you have is so worn it’s stripping the pins inside the lock. If a key snapped in a deadbolt on E Cotati Avenue, we extract the broken piece and cut a new key on the spot. If the key is just worn, we can decode the existing one and cut a fresh copy that actually works. Replacing a standard residential key for a Kwikset or Schlage lock in Cotati typically runs $12 to $25 per key, and if the cylinder itself is damaged, a new cylinder runs $35 to $70 installed.
What you’ll pay for key replacement in Cotati depends on what the lock accepts. A plain kwikset keyway is straightforward. An older Baldwin or Medeco cylinder with restricted key blanks costs more because the blanks aren’t something a hardware store stocks. We carry those blanks on the truck, which is why a Cotati call usually wraps up in one visit instead of two.
Broken Key Extraction
When a key breaks off flush with the face of the lock, the fix is usually a spiral extractor that hooks the broken blade and works it out. Most Cotati jobs like this take under 20 minutes. If the key broke because the cylinder is failing, we’ll tell you before replacing anything, with the price for the cylinder spelled out.
Replacement After a Lost Key
If you lost a key and can’t account for where it went, we recommend rekeying rather than just cutting a replacement. Rekeying the lock in Cotati means we change the internal pins so the old key no longer works. On standard single-cylinder deadbolts and entry knobs, expect $18 to $30 per cylinder, and a typical front door with a knob and deadbolt runs $36 to $60 to rekey both, plus a service call if you’re outside our standard dispatch window for Cotati.
Smart Lock Installation in Cotati
Smart Lock Installation in Cotati means mounting a keypad, touchscreen, or keyless-entry deadbolt and making sure it actually aligns with the existing door prep. Cotati homes built in the 1960s and 70s often have narrower bore holes or mortise-style prep that doesn’t match modern smart lock templates. We remove the old hardware, widen the prep where necessary, install the new smart lock, and program codes while you watch. Standard installation for a Schlage Encode or similar Wi-Fi deadbolt in Cotati runs $90 to $160 for labor, plus the hardware cost if you haven’t bought the lock yet.
Before you buy a smart lock online, call us. We can tell you whether the unit you’re looking at will fit your Cotati door or whether you’re about to order something that needs a faceplate adapter and a chisel. That ten-minute phone call has saved Cotati homeowners from printing return labels more times than we can count.
Mortise Lock Conversions
The downtown Cotati blocks and west-side streets are full of 1950s and 60s doors with original mortise lock bodies. A mortise lock isn’t an obstacle for a smart lock install, but it does change the scope. We remove the mortise body, fill the pocket if needed, and prep the door for a standard cylindrical deadbolt. Expect an extra $30 to $50 in labor on a Cotati mortise conversion versus a standard swap.
Code Setup and App Pairing
We set your codes, pair the lock to your phone or Wi-Fi, and delete the factory defaults before we leave. You get a walkthrough on how to add and remove users. If you’re renting out a unit near Cotati’s downtown, we’ll set up temporary codes that expire.
Trusted Brands We Service in Cotati
We stock parts and key blanks for the hardware Cotati homeowners actually have on their doors. That means Schlage and Kwikset for everyday deadbolts and knobs, Medeco for high-security cylinders, and Yale for the growing number of smart locks showing up on newer builds and remodels. Because we carry those parts on the truck, a deadbolt rebuild or a rekey doesn’t turn into a two-trip job with a “parts are on order” phone call. If your lock needs a specific tailpiece or a Medeco sidebar, it’s probably in the van before we pull up to your Cotati address.
Common Residential Locksmith Problems We See in Cotati Homes
- Mismatched hardware on downtown-era doors. Original mortise locks on the front door, newer deadbolts above them, and two different keys. We re-pin the mortise body and key the deadbolt alike so one key runs everything.
- Sticky thumb-turns on west-side deadbolts. Cotati’s fog-in-the-morning, dry-by-noon cycle pulls moisture into unsealed door hardware. Over time, internal springs bind and the thumb-turn gets stiff. A clean, lubricate, and pin-and-tumbler refresh typically fixes it without replacing the lock.
- Renter turnover rekeys near Sonoma State. Landlords with units near Petaluma Hill Road or Gravenstein Highway need rekeys done between tenants, often same-day. We handle multiple cylinders per visit and keep keys organized by unit.
- Drilled locks from a previous locksmith. When someone shows up to a Cotati lockout and reaches for a drill first, the lock usually gets destroyed. Most Cotati residential doors open without drilling. If your lock was drilled before, we’ll replace the cylinder and get your key working again.

FAQs About Residential Locksmith in Cotati
Yes. A standard Cotati rekey is $18 to $30 per cylinder for most Schlage and Kwikset locks. We confirm the lock type when you call, give you a firm written total before dispatch, and that’s the number on the invoice. Call (409) 405-4485 and you’ll have the exact price in about five minutes.
No, it just changes the prep work. We remove the mortise body and re-drill the door for a standard cylindrical deadbolt, which adds about $30 to $50 in labor on top of the standard smart lock install. We’ll tell you the exact total before we start.
Almost never. Most Cotati residential doors with standard deadbolts and knobs open with non-destructive entry tools in under ten minutes. We only drill as a last resort on damaged or non-standard hardware, and we’ll tell you the cost before we do it.
Rekeying swaps the internal pins and springs inside the cylinder so the old key no longer works. The lock housing, knob, and deadbolt stay in place. It’s the fastest way to invalidate old keys without buying new hardware. In Cotati, most rekeys take 15 to 20 minutes per lock.
