Rekeying locks in Chinatown means working with 100-year-old mortise locksets, skeleton-keyed doors, and hardware that the fog has been working on since the building went up. Cypress Lock & Key has served Chinatown since 2017, and most of our jobs here start the same way: a tenant moved out, a family association changed who holds the keys, or a shop gate on Grant won’t budge at 6 a.m. Call (877) 265-4385 and we’ll tell you exactly what the job involves before anyone gets in a van.
Why Chinatown Homes Are Different
Chinatown (94133) holds some of the densest, oldest residential building stock in San Francisco. We’re not walking into 1990s track homes with standard Schlage deadbolts. We’re walking into post-1906 brick and woodframe buildings, SRO residential hotels with sharedentry systems, and narrow storefronts where the front door still runs on a rim lock that predates the tenant’s grandparents. The work is different for a reason: much of the hardware is original or salvaged, not off-the-shelf. A worn cylinder in a 1912 mortise body doesn’t get replaced with a trip to the supply house. It gets measured, matched, and often reconditioned in place.
The fog shapes the work too. Chinatown sits in a perpetually damp microclimate where iron gates, hinges, and older lock bodies corrode faster than anywhere inland. We see seized padlocks on Stockton roll-down gates every week, and the fix usually starts with freeing the rust before we even talk about keys. Add narrow stairwells, six-story walkups, and the fact that a landlord may live in Daly City while a Cantonese-speaking property manager holds the actual access, and you get jobs that reward patience, documentation, and a technician who knows the difference between a clamshell mortise and a rim cylinder without having to look it up.
Styles & brands we work with
Our Main Chinatown Services
Two services generate most of the calls we get from Chinatown homeowners, shopkeepers, and property managers. Here’s what each involves in this neighborhood.
Car Key Replacement in Chinatown
Street parking in Chinatown is a competitive sport, and when a car key snaps in an old ignition or disappears between deliveries on Stockton, towing to a dealership across town is the last thing anyone wants. We cut and program replacement keys on-site, including transponder and fob-based systems, so the car stays where it’s parked. Our van carries equipment for most major makes, which means a dealership invoice doesn’t get added to the day’s losses. Read the full breakdown on our dedicated page for Car Key Replacement in Chinatown.
Emergency Locksmith in Chinatown
A locked-out tenant on Jackson at 11 p.m., a shop gate that won’t release on Grant before the morning dim sum rush, a back door that finally gave out on a family association building: these are Chinatown emergencies, and they don’t wait for business hours. We respond around the clock, and a real person answers the phone, not a voicemail script. The goal is the same whether it’s a residential lockout or a seized commercial gate: get you back inside, calmly, without damage to hundred-year-old woodwork. Details are on the Emergency Locksmith in Chinatown page.

Rekey Locks in Chinatown
Rekeying is the smartest, least expensive security upgrade you can do after a tenant moves out, a relationship ends, or keys have been floating around a family association for years. In Chinatown, rekeying usually means reworking what’s already there rather than swapping hardware, because the existing lockset is often a mortise body that was installed before World War II and fits the door like nothing modern ever will. We rekey the lock you already have, changing the internal pins so old keys stop working while the hardware stays intact. That’s the whole point: new keys, same door, no replacement cost. For more on the process, see Rekey Locks.
Lock Rekey
Signs you need it
You have no idea how many copies of your key exist, or who has them.
What it costs in Chinatown
Standard cylinder rekeying in Chinatown typically runs $85 – $140 per lock, with simple Kwikset or Schlage cylinders at the low end and older mortise cylinders requiring more labor at the high end.
How we do it
We remove the cylinder, swap the internal pins to a new key, reassemble it, and test the lock through a full cycle before we leave.
Rekey Door Lock
Signs you need it
You just bought or inherited a building and the previous owner, a relative, or a former property manager still has a working key.
What it costs in Chinatown
Rekeying a single door lock in Chinatown is typically $95 – $150, depending on whether it’s a modern deadbolt or a mortise body that needs field reconditioning.
How we do it
We disassemble the lock, pull the old pins, load a fresh set matched to your new key, lubricate the internals, and confirm the key works smoothly from both sides.
Keyed Alike
Signs you need it
You carry a ring of four different keys for one building and want a single key to open everything.
What it costs in Chinatown
Keying multiple locks alike in Chinatown typically runs $110 – $160 per lock for the rekey work, with the cost per additional lock dropping slightly as cylinder count rises.
How we do it
We set all your cylinders to the same pin configuration, cut the agreed number of keys, and test every lock in the building with that single key before we finish.
What Rekey Locks Costs in Chinatown
| Item | Typical range in Chinatown |
|---|---|
| Per-lock rekey (standard cylinder) | $85 – $140 |
| Per-lock rekey (mortise or locking hardware) | $95 – $150 |
| Standard key copy | $6 – $12 |
How long does rekeying take in Chinatown?
Most rekey jobs are done in 30 to 45 minutes per lock, and we finish same day in nearly all cases. Call (877) 265-4385 for a firm quote and a time window before anyone is dispatched.
Can you rekey a 100-year-old mortise lock without replacing it?
Yes. We rekey and recondition original mortise locks regularly in Chinatown, keeping the historic hardware in place while retiring every old key. The price stays in the range above unless the cylinder is seized beyond repair.
Brands We Service in Chinatown
We work on the lock you already have, and that matters in Chinatown more than most places. Our technicians carry parts and blanks for Mul-T-Lock, Sargent, Abloy, and Schlage, among others, so a high-security cylinder on a family association door doesn’t get downgraded to a generic replacement. Most standard parts are stocked in our van, which means same-day turnaround on the vast majority of jobs. See our brands for the full list.

FAQs About Locksmith in Chinatown
Yes. Our dispatch line can field calls in Cantonese and English, and we regularly coordinate with family associations and property managers on Grant and Stockton who prefer to discuss access permissions in Cantonese before we touch a lock.
In most cases, no. Rekeying your own unit is standard tenant and owner work. If you’re in a family association building or an SRO with shared entry, we’ll confirm who holds permission for common-area doors before touching anything, so you’re not the one explaining it later.
Yes. Shop roll-down gates and back-door lockouts on Grant, Stockton, and Jackson are common after-hours emergencies, and we respond around the clock. Call (877) 265-4385 with the address and the gate or lock condition, and we’ll give you a straight answer on arrival time.

What Chinatown Customers Say
"Quoted a price on the phone and honored it. After the last locksmith I called, that alone is worth a review."
— Sarah Vaughn"Got me back in and the price was fair for the hour. He did arrive closer to 45 minutes than the 20 he estimated, which felt long standing outside, but he was honest that traffic was the problem."
— Marcus Prince"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."
— Lisa Sullivan
