Fast, Reliable Rekey Locks Across Sonoma
Rekeying a lock in Sonoma typically costs $25 – $45 per cylinder for standard Schlage or Kwikset hardware, and most jobs wrap up in under an hour. The written price you get on the phone is the price on the invoice, no call-out surcharge added when the van pulls up. We serve Sonoma daily, from the Plaza to the east-side subdivisions, with a live arrival time you can track before the tech knocks. Call (409) 405-4485 for a free estimate in the next five minutes.
Sonoma’s mix of housing means a Rekey Locks job here rarely looks like what a national YouTube video shows. We’re talking century-old mortise locks on Victorian doors near downtown and 1990s builder-grade Kwikset knobs in the subdivisions off Arnold Drive. We know both. That local knowledge is why Sonoma homeowners call us instead of gambling on a four-hour arrival window and a price that changes at the doorstep.
Why Preston Locksmith & Security Is Sonoma’s Preferred Rekey Locks Company
We answer the phone with a live person, 24/7. No voicemail tree, no callback queue. When you call about rekeying a lock in Sonoma, you get a written price before anyone is dispatched, and that price is locked before the tech leaves the shop. Kevin Yoon, our owner, built this company on a simple rule: the person at your door should be background-checked, uniformed, and carrying a price you already agreed to.
Every Sonoma job is covered by the 365-Day Done Right Promise. If a rekey isn’t done right, we come back and fix it at no charge. That promise is stamped on every repair, in writing. Customers near Maxwell Farms and the Springs have told us the photo-update system is what sealed it for them: you see before-and-after photos of every lock we touch, so there’s no question what was done inside the cylinder.
We’re part of the Relay Home Co. family, independently owned and operated since 2008. The Relay Visibility Guarantee is on every job we run in Sonoma: a live trackable arrival time, before-and-after photos, a written price before work begins, and a written guarantee on the repair itself. No anonymous tech, no vague hourly rates, no “starting at” bait.

Keyed Alike in Sonoma
Keyed alike in Sonoma means re-pinning multiple locks so one key operates all of them. It’s the most common rekey request we get from Sonoma homeowners, especially after a purchase or a tenant move-out. A family closing on a home near the Plaza handed us a set of mismatched keys: a Schlage deadbolt on the front door, an older Kwikset knob on the back, and no key that worked the side gate. We pulled each lock cylinder, re-pinned them to a single key in about forty minutes, and left the original brass mortise hardware on the front door untouched because the homeowner wanted to keep it. One key, three doors, no drilling. Keyed alike in Sonoma typically runs $25 – $45 per cylinder plus a service call, with the total written before we start.
Matching Existing Hardware Without Replacing It
Keyed alike doesn’t require buying new locks. We re-pin the internal pins inside each cylinder so the old keys stop working and a single new key takes over. On Sonoma’s older mortise locks, we preserve the brass faceplate and the original hardware; only the pins inside change. If a lock is worn past safe re-pinning, we tell you before we touch it, and we show you the replacement price in writing first.
When Sonoma Homeowners Key Alike
The typical triggers: closing on a home and not knowing who still holds a key, a tenant leaving a rental on Fifth Street West, or a homeowner tired of carrying five keys for five doors. Landlords in the Springs and near Sonoma Valley High School often have us key alike the front and back doors plus a gate so one key manages the whole property.
Rekey Deadbolt in Sonoma
Rekey deadbolt in Sonoma means changing the internal pins inside the deadbolt cylinder so the existing key no longer operates it. The deadbolt itself stays in the door, which matters here because Sonoma’s split housing stock means we’re often rekeying a modern Schlage B60 deadbolt on a 1990s east-side home or a Baldwin deadbolt on a Plaza-area Victorian. Rekeying a deadbolt in Sonoma runs $25 – $45 per cylinder, and we confirm the exact figure before anyone drives out.
Single-Cylinder vs. Double-Cylinder Deadbolts
Most Sonoma homes have single-cylinder deadbolts: keyed outside, thumbturn inside. Some older homes near Spain Street still carry double-cylinder deadbolts that need a key on both sides. Double-cylinder rekeys are identical in price per cylinder, but we also check fire-code implications with you before the work, since a keyed interior can slow an exit in an emergency.
Checking Key Control While We Rekey
We verify the deadbolt’s grade and bump-resistance during the rekey. A rental flip in Sonoma might tolerate a builder-grade Kwikset, but a primary residence deserves ANSI Grade 1 hardware. If a deadbolt is worn, we show you what’s replaceable and what it costs. No forcing the hardware, no cracking the faceplate, no surprise upgrade charges.
Trusted Brands We Service in Sonoma
We rekey standard and high-security hardware across Sonoma, and we stock common pin kits locally so turnaround stays fast. We’re trained and equipped on Schlage, Kwikset, Medeco, Yale, Baldwin, Mul-T-Lock, Sargent, and Abloy cylinders, from residential deadbolts to small-business storefront locks. That means a Sonoma homeowner with a Schlage deadbolt gets it rekeyed same-day without waiting for a part. A business near Broadway with Medeco high-security cylinders gets a key-control conversation before we touch anything.
Common Rekey Locks Problems We See in Sonoma Homes
- Mismatched cylinder brands on one house. A century-old home near the Plaza often has a Schlage deadbolt, a Kwikset knob, and a mortise lock on the side door. One key can still run all of them; we re-pin each cylinder to match, no hardware replacement needed.
- Builder-grade Kwikset knobs on east-side homes. The 1980s-90s subdivisions off Arnold Drive were built with Kwikset hardware. It’s fine for rekeying, but we point out bump-resistance and grade differences so a primary residence isn’t left with rental-grade key control.
- ‘Starting at’ price changed at the door. A Sonoma homeowner gets a phone quote, then the tech arrives and says the mortise lock needs a different cylinder kit. The number changes on the doorstep. Our price is written before dispatch and doesn’t move.
- Old mortise faceplates cracked during the rekey. Some homes downtown still have original mortise locks. Forcing the cylinder can crack the faceplate and turn a rekey into a full hardware replacement. We use a non-destructive entry approach and leave the original brass intact.

Here’s the straight answer: standard rekeying in Sonoma runs $25 – $45 per cylinder.

FAQs About Rekey Locks in Sonoma
Yes. You approve a written price before dispatch, and that’s the price on the invoice. No call-out surcharge added on arrival, no changing the quote because a mortise lock needs a different kit. Call (409) 405-4485, describe your locks, and you’ll get the exact figure before the van leaves.
Yes, that’s keyed alike. We re-pin each cylinder so a single key operates every door. It works across brands: Schlage deadbolt, Kwikset knob, even an original mortise lock near the Plaza. We did exactly this for a family near the Plaza: mismatched keys, one key afterward, no drilling.
Most Sonoma jobs with one to four locks take 30 to 60 minutes on site. High-security Medeco or Mul-T-Lock cylinders add time because the pins are matched differently and require more precise work. You’ll see the live arrival time before we leave and before-and-after photos after we finish.
Our tech is uniformed, background-checked, and tracked on a live map from dispatch to your Sonoma door. You’ll see a photo and name before the knock, not just a phone-call description. Then you get before-and-after photos of every lock we touched, and a written guarantee on the repair itself.
No. We remove the cylinder and re-pin it, keeping the original brass mortise faceplate and hardware untouched. We don’t force anything. If a lock is too worn to re-pin, we stop and show you the replacement option with a written price before proceeding.
