Rekeying locks is the most common call we handle in San Francisco, and the city’s housing stock makes it a different job here than anywhere else in the Bay Area. Most homes were built between 1900 and 1930, which means original mortise locksets, settling wood frames, and decades of accumulated keys held by former tenants, contractors, and neighbors. Citadel Locksmith has served San Francisco since 2011, and we rekey everything from single-family flats on the hills to full Victorian multi-unit buildings where three generations of keys are still floating around. Call (833) 589-8078 for a free estimate, and we’ll tell you the exact price before anyone is dispatched.
Why San Francisco Homes Are Different
San Francisco locksmith work is dominated by dense pre-war multi-unit buildings. The endless rows of Victorian and Edwardian flats, along with the city’s stock of single-room-occupancy hotels, often carry dozens of mismatched, century-old mortise locks on a single building. These shared front doors have been rekeyed by generations of landlords, and the original ornate hardware frequently cannot be swapped for a modern deadbolt without altering a protected facade.
The marine fog and damp Pacific air keep San Francisco mild but persistently humid. Exposed exterior hardware, gate locks, garage doors, and alley entry sets, corrodes and seizes faster than in drier California cities, with salt air near the Marina, Dogpatch, and the Embarcadero accelerating it further. The rainy winter season swells wood doors and jambs, a common cause of suddenly stuck deadbolts and misaligned strikes in older buildings.
In hillside neighborhoods like Noe Valley, Bernal Heights, and Potrero Hill, steep staircases and shared garden gates mean a huge share of calls are for gate and garage-door locks rather than front doors. The sloping lots make door frames rack and stick as the ground shifts, so a lock that worked fine in dry September often won’t turn after the first winter rains. Add in rent-controlled, tenant-occupied buildings where landlords, property managers, and longtime tenants all have competing claims to a key, and you have a city where rekeying is less about convenience and more about knowing exactly who holds access to a building.
Styles & brands we work with







Our Main San Francisco Services
Most San Francisco residents call us for two things: they’ve lost a car key and need a replacement without the dealership markup, or they’re locked out, or dealing with a security concern, and need someone now. Here’s how each works in the city.
Car Key Replacement in San Francisco
San Francisco’s narrow streets, scarce parking, and frequent parallel-parking shuffles mean car keys get lost or broken more often than people expect. We cut and program replacement keys for most major makes and models, typically for hundreds less than a dealership quote, and we come to you, whether you’re parked near Golden Gate Park, in the Outer Sunset, or down by the waterfront. The city’s damp air also corrodes key fob contacts faster than inland, so intermittent failure is a common precursor to full failure. We carry the programming equipment to handle most jobs on the spot. Learn more about Car Key Replacement in San Francisco.
Emergency Locksmith in San Francisco
Lockouts in San Francisco happen at odd hours, often in buildings where the front gate and the unit door are both locked, and where a landlord is unreachable or out of town. We respond to urgent calls across the city, from the Mission to the Richmond, and we know how to open older locks without damaging vintage hardware. The security-first approach means we verify who belongs before opening anything, which matters in a city with dense multi-unit occupancy. Read more about how we handle urgent calls at Emergency Locksmith in San Francisco.

Rekey Locks in San Francisco
Rekeying in San Francisco is usually about taking back control of a building where too many keys are unaccounted for. The city’s 1900 – 1930s Victorian and Edwardian housing stock, along with a large stock of early-1900s apartment buildings and SROs, was built with mortise locksets and rim locks that landlords have rekeyed for decades, sometimes with mismatched cylinders and non-standard backset dimensions. That means a standard rekey here often involves working with vintage hardware that big-box replacement parts can’t address. The damp marine air also means exterior locks in San Francisco corrode and seize faster than inland, so a rekey often includes cleaning and lubricating the cylinder internals, not just swapping pins. For background on the full rekeying process, see our Rekey Locks page.
Lock Rekey
Signs you need it
You’ve moved into a new place, a roommate or tenant moved out, or you can’t account for every copy of your key.
What it costs in San Francisco
A standard lock rekey in the city typically runs $75 – $150 per cylinder, including the service call.
How we do it
We remove the cylinder, replace the internal pins so old keys no longer work, cut new keys to match, and test the lock before we leave.
Rekey Door Lock
Signs you need it
Your door lock feels gritty or stiff in the damp air, a recent tenant dispute has you worried about key copies, or you bought a home and the previous owners never changed the locks.
What it costs in San Francisco
Rekeying a door lock in San Francisco typically runs $75 – $150 per cylinder, and if the cylinder is too corroded to rekey, a new one adds roughly $30 – $90.
How we do it
We gauge the cylinder, install new pins to match a fresh key, lubricate the internals for the marine air, and adjust the strike plate if the old wood frame has settled.
Keyed Alike
Signs you need it
You carry separate keys for the front gate, the front door, the garage, and the back door, and you’re tired of the jangling mess.
What it costs in San Francisco
Keying multiple locks alike in San Francisco typically costs $75 – $150 per cylinder, with the per-cylinder rate dropping somewhat when we do several locks in one visit.
How we do it
We pin each cylinder to the same key code, then test every lock and key together so one key turns every lock in the set.
What Rekey Locks Costs in San Francisco
| Item | Typical range in San Francisco |
|---|---|
| Standard cylinder rekey | $75 – $150 per cylinder |
| New cylinder (if the old one is corroded or worn) | $30 – $90 per cylinder |
| Service call / trip charge | Quoted on the phone, included in the estimate |
Two things push the price up in San Francisco more than elsewhere. First, vintage mortise locks from the 1920s often need disassembly and cleaning, not just a quick pin swap, because decades of fog moisture have gummed up the internals. Second, hillside gate locks and alley entry sets are frequently so corroded that the cylinder can’t be rekeyed at all and must be replaced. We quote the full price on the phone before anyone is dispatched, and that is the price on the invoice. There is no added call-out surcharge when the tech arrives.
How long does rekeying take in San Francisco?
Most standard rekeying jobs in the city take 20 – 40 minutes for the first lock and 10 – 15 minutes per additional cylinder. Older mortise locks in Victorian and Edwardian buildings may take longer if they need cleaning or the frame has settled. Call (833) 589-8078 for a time estimate on your specific building.
Can you rekey my landlord’s door if I’m a renter?
We rekey only with authorization from the property owner or the person legally responsible for the unit. Bring your lease, and we will confirm you have the right to request the work before we touch the lock. This protects tenants and landlords alike in San Francisco’s multi-unit buildings.
Brands We Service in San Francisco
We work with Schlage, Kwikset, Medeco, and Yale hardware throughout San Francisco, and we stock common replacement parts for these brands rather than ordering and waiting. If you have a high-security Medeco cylinder or an original Yale mortise lock in a Pacific Heights flat, we can typically service it the same visit. See our brands for the full range.
Pricing for Locksmith in San Francisco, CA
| Service | Typical range in San Francisco |
|---|---|
| Standard lock rekey | $75 – $150 per cylinder |
| New cylinder (replacement) | $30 – $90 per cylinder |
| Car key replacement | Quoted by make and model |

The biggest price drivers in San Francisco are the age of the hardware and the condition of the door frame, not the lock brand itself. A 1925 mortise lock that has absorbed forty years of fog moisture takes more labor than a clean modern deadbolt, and a hillside door frame that has racked out of square often needs a strike plate adjustment for the lock to work smoothly. We quote the full price on the phone before anyone is dispatched, and the number we quote is the number on your invoice. No added call-out surcharge, no bait-and-switch.
Neighborhoods We Serve in San Francisco
We cover every neighborhood in the city, from the dense Victorians of the Mission and Hayes Valley to the hillside stair-streets of Potrero Hill, Noe Valley, and Bernal Heights, up through the Richmond and the Sunset, and over to the waterfront areas near the Marina, Dogpatch, and the Embarcadero.
