Rekeying is the fastest way to take back control of who holds a key, and in Sonoma it’s rarely a simple five-minute job. The homes here, from 19th-century adobes near the Plaza to wine-country estates off Arnold Drive, carry hardware that demands a locksmith who understands old mortise pockets and modern cylinders equally. Citadel Locksmith has served Sonoma since 2011, rekeying everything from original skeleton-key front doors to rental properties that need keyed-alike systems for cleaners and property managers. Call (833) 589-8078 for a direct quote before anyone is dispatched.
Why Sonoma Homes Are Different
Sonoma’s lock and key landscape is split between 19th-century adobe and wood-framed buildings around the Plaza and along Spain Street, many with original mortise locks, skeleton keys, and hand-forged iron hardware, and wine-country estates and vacation rentals whose owners want master-key systems and smart locks tied to property managers. A locksmith here must be part historian, part security-tech, because a single day can mean rekeying a 150-year-old Victorian front door with antique brass and installing a Bluetooth lockbox for a rental on a vineyard property.
Near the Plaza, many front doors still have their original mortise locks with skeleton keys, and homeowners often ask for those locks to be repaired and matched with modern deadbolts, a job that’s routine in Sonoma but rare in most California suburbs. The housing stock ranges from 1840s to 1900s adobe, stone, and wood-frame buildings to mid-century ranch homes along East Napa Street and newer estates in the hills above Lovall Valley Road. Trades often encounter doors that have been retrofitted many times, so lock replacement usually involves repairing old mortise pockets with custom strikes or rebuilding jamb reinforcement.
Sonoma’s hot, dry summers and damp winters cause wooden doors and frames to swell and shrink, making lock alignment and strike plates a recurring seasonal issue. The same dry conditions oxidize exterior hardware, so locksmiths here routinely free up or replace corroded brass and iron locksets. What looks like a lock failure is often a door that moved, and fixing that correctly means resetting the strike, not just swapping the cylinder.
Styles & brands we work with







Our Main Sonoma Services
Sonoma homeowners and drivers call Citadel most often for two things: replacing car keys without a dealership markup, and emergency lockout response when a door closes at the wrong moment. Both are covered below, each with a dedicated page for Sonoma.
Car Key Replacement in Sonoma
Lost or broken car keys hit harder in Sonoma than in a dense metro, because the nearest dealership might be a drive over the hills toward Petaluma or Napa. Citadel cuts and programs replacement keys, transponder chips, and fobs on-site, typically for less than half of what a dealership quotes. The hot, dusty summers here are hard on key fobs left in a car or on a patio table, and we see failures from corroded contacts and cracked casings more often than electronic board damage. If your key is gone entirely, we can originate a new one from the vehicle’s VIN. See Car Key Replacement in Sonoma for the full scope and pricing.

Emergency Locksmith in Sonoma
A lockout at midnight off Broadway or a broken deadbolt on a rental check-in day doesn’t wait for business hours. Citadel’s emergency service model is built around being reachable when security can’t wait, not as an afterthought. We handle residential lockouts, snapped keys, and failed hardware on homes across Sonoma, and we arrive with the tooling to open a door without destroying the lock whenever possible. If a lock must be drilled, we replace it on the same visit. See Emergency Locksmith in Sonoma for response details and typical costs.

Rekey Locks in Sonoma
Rekeying in Sonoma means working around old hardware that big-box replacements won’t fit, because so many doors near the Plaza still carry original mortise locks with skeleton keys. Rekeying is the fastest way to take back control of who holds a key, and in Sonoma it often costs less than replacing antique brass or cast-iron hardware that can’t be matched at any hardware store. Citadel rekeys standard tubular deadbolts, mortise-lock cylinders, rim locks, and high-security systems from Medeco and Mul-T-Lock without changing the visible hardware. For the broader scope of our rekey work, see Rekey Locks.
Lock Rekey
Signs you need it
You’ve moved into a new home, ended a relationship, lost a key, or can’t account for every copy that was ever handed out.
What it costs in Sonoma
Standard lock rekeying in Sonoma typically runs $20 to $35 per cylinder, which is the labor to repin and test the lock while you keep your existing hardware.
How we do it
We remove the cylinder, replace the internal pins to match a new key, then test the lock in the door to confirm the old key no longer turns and the new one operates smoothly.
Rekey Door Lock
Signs you need it
A tenant or guest has moved out, a contractor still holds a key, or you simply want one key that operates every exterior door.
What it costs in Sonoma
Rekeying a door lock runs $20 to $35 per cylinder, with most Sonoma homes running two to four cylinders on exterior doors.
How we do it
We rekey each cylinder to match a single key, then adjust strike alignment where Sonoma’s seasonal door swelling has thrown the bolt off center.
Keyed Alike
Signs you need it
Your key ring has five different keys for one property, or you manage a rental and want one key that opens the front door, back door, and garage.
What it costs in Sonoma
Keyed alike work costs $20 to $35 per cylinder, plus the cost of cutting matching keys, which typically adds only a few dollars per key.
How we do it
We pin every cylinder in the set to the same shear line, so a single key operates all included locks, then test each one in the door before we leave.
What Rekey Locks Costs in Sonoma
| Item | Typical range in Sonoma |
|---|---|
| Rekey, standard cylinder | $20 – $35 per cylinder |
| Rekey, high-security cylinder (Medeco, Mul-T-Lock) | $30 – $55 per cylinder |
| Service call / trip charge | $45 – $95, quoted before dispatch |
These figures reflect what we see across Sonoma. Historic mortise locks near the Plaza sometimes run slightly higher than a standard tubular deadbolt because the cylinder is harder to pull, and high-security systems like Medeco require specialized pins and more time. The full price is quoted on the phone before anyone is dispatched, and that is the price on the invoice. There is no call-out surcharge added on arrival.
How long does rekeying take in Sonoma?
Most Sonoma homes rekey in 30 to 60 minutes for two to four cylinders. Homes with original mortise locks or multiple outbuildings run longer, and we will tell you the expected time when you call.
Is rekeying better than replacing locks in Sonoma?
Usually yes, especially when the existing hardware is antique brass or iron that you cannot buy anymore. Rekeying keeps the original look while eliminating old keys, and it typically costs less than replacing quality hardware.
Brands We Service in Sonoma
Citadel carries pins, cylinders, and key blanks for Schlage, Kwikset, Medeco, and Yale, so most rekey and repair jobs in Sonoma are completed in a single visit without waiting on parts.

Pricing for Locksmith in Sonoma, CA
| Service | Typical range in Sonoma |
|---|---|
| Rekey, standard cylinder | $20 – $35 per cylinder |
| Rekey, high-security cylinder | $30 – $55 per cylinder |
| Service call / trip charge | $45 – $95, quoted before dispatch |
| Deadbolt or lockset replacement | $80 – $180 per lock |
| High-security deadbolt installation | $150 – $300 per lock |

Prices in Sonoma push toward the higher end on homes with original mortise locks or cast-iron rim locks, because the labor to remove, repin, and reinstall those cylinders is greater than a standard tubular deadbolt. Hardware replacement adds the cost of the new lock itself. Whatever the number, the full price is quoted on the phone before anyone is dispatched, and that is the price on the invoice.

What Sonoma Customers Say
"The old deadbolt was mounted crooked by whoever lived here before and had been sticking for years. He redrilled and reset it properly rather than just replacing the hardware."
— Brandon Wong"Installed a smart lock and actually set up the app and the codes with me instead of leaving me to figure it out from a leaflet."
— David Nguyen"Something came loose about a month after the work. Called them, and they were back out the next day and fixed it at no charge. Didn't argue, didn't try to bill me for the trip."
