Rekeying is the service San Bruno homeowners and landlords call about most, and for good reason. The city’s 1940s and 1950s housing stock holds thousands of original mortise locksets and brass entry knobs that have outlived multiple owners, former tenants, and lost key rings. Citadel Locksmith has served San Bruno since 2011, and we know exactly how fog-season humidity, original hardware wear, and constant rental turnover shape every rekey job here. Call (833) 589-8078 for a free estimate on rekeying your San Bruno home or rental.
Why San Bruno Homes Are Different
San Bruno’s lock and key problems come from a specific collision of housing age and marine weather you won’t find in most Peninsula cities. The flats between El Camino Real and the bay, along with the Crestmoor and Rollingwood tracts up the hill, are dense with post-WWII stucco-over-woodframe homes built between 1945 and 1959. Those original mortise locksets and brass entry knobs still work, mostly, but the internal springs wear out, the strike plates loosen, and the cylinders get sloppy. Homeowners in Bayside and Crestmoor regularly ask us whether a failing original lock can be rebuilt rather than replaced. Often it can.
San Bruno’s fog-cooled marine climate does not produce the extreme heat that cracks and warps hardware in inland cities, but it brings persistent humidity and salty air off the Bay. Exterior brass and steel entry sets pit slowly, and gate locks near the Bayside corridor corrode faster than anything on the hill. Fog-damp mornings also swell wooden doors, which then jam against worn strike plates. In the older tracts, our techs learn to adjust the strike and lubricate the mortise body before ever recommending a full replacement. That repair-first instinct saves San Bruno homeowners real money.
Styles & brands we work with
Our Main San Bruno Services
Two service calls dominate our work across San Bruno’s 94066 ZIP code: car key replacement for drivers who cannot afford dealership pricing or waits, and emergency locksmith response for renters, homeowners, and airport-shift workers locked out at night. Both get their own dedicated pages below.
Car Key Replacement in San Bruno
San Bruno sits between SFO and the El Camino corridor, which means a lot of residents work airport shifts at odd hours and park in shared lots or street spaces. Losing a car key or snapping a fob here is not a minor inconvenience, it is a work problem. We cut and program replacement keys and fobs for most makes, often the same day, without the dealership markup. For the full picture on transponder keys, proximity fobs, and same-day turnaround in San Bruno, see Car Key Replacement in San Bruno.
Emergency Locksmith in San Bruno
Rental turnover near the BART station and San Bruno Avenue creates a steady stream of after-hours lockouts, and the older single-family homes on the flats have their share of broken-key-in-lock and frozen-cylinder emergencies. We are built for emergency response, not as an add-on to a 9-to-5 shop. When you are locked out in the fog at midnight, a real person answers. See Emergency Locksmith in San Bruno for how we handle urgent calls across the city.

Rekey Locks in San Bruno
San Bruno’s rental density near the BART/El Camino corridor and its long-tenured owner-occupant neighborhoods both drive rekey demand, but for different reasons. Landlords rekey between every tenant; homeowners rekey after a break-in scare, a divorce, or a lost key that never turned up. Because so many San Bruno homes still carry original 1950s mortise locks and worn brass knobs, rekeying here often means working on hardware most locksmiths would rather rip out and replace. Rekeying is the fastest way to take back control of who holds a key, and our techs rebuild the cylinder from the inside rather than telling you to buy new hardware. For a deeper look at the process, see Rekey Locks.
Lock Rekey
Signs you need it
You have moved into a new San Bruno home or apartment and cannot account for every key a previous owner, tenant, or contractor may still hold.
What it costs in San Bruno
Standard lock rekeying in San Bruno typically runs $25 to $35 per cylinder for labor, plus a service fee, with total job cost depending on how many locks you have.
How we do it
We remove the lock cylinder, replace the internal pins so the old keys stop working, cut new keys to match, and reinstall the cylinder in the same housing.
Rekey Door Lock
Signs you need it
A brass entry knob or mortise lock on a 1940s or 1950s San Bruno home turns hard, sticks, or no longer aligns with the strike plate on fog-damp mornings.
What it costs in San Bruno
Rekeying a single door lock in San Bruno falls in the $30 to $50 range for the cylinder service, including the new key cut, before any hardware rebuild is added.
How we do it
We pull the cylinder, inspect the mortise body and strike alignment, repin the cylinder to a new key, and adjust the strike plate so the swollen wood door latches cleanly.
Rekey Service
Signs you need it
You have multiple locks on different doors using different keys and want every entry point in your San Bruno home or rental working from a single key.
What it costs in San Bruno
Whole-property rekey service in San Bruno, covering three to six cylinders, typically lands between $75 and $175 before any additional keys or hardware parts.
How we do it
We rekey each cylinder to a shared key schedule, cut the new keys, test every door, and leave you with one key that turns every lock we serviced.
What Rekey Locks Costs in San Bruno
| Item | Typical range in San Bruno |
|---|---|
| Labor per cylinder (rekey) | $25 – $35 |
| Single door lock rekey (with new key) | $30 – $50 |
| Whole-property rekey (3 – 6 cylinders) | $75 – $175 |
What pushes a San Bruno rekey price up is not the rekey itself, it is the condition of the surrounding hardware. Original mortise bodies with worn internal springs, corroded brass collars from salty fog air, or misaligned strikes on swollen doors all need repair work on top of the cylinder repinning. We quote that full price on the phone before we dispatch, and that is the price on the invoice. No call-out surcharge added on arrival.
How long does rekeying take in San Bruno?
Most San Bruno rekey jobs are done within 30 to 60 minutes on site, depending on cylinder count and whether we need to rebuild worn mortise internals. We quote the labor before starting.
Can you rekey an original 1950s mortise lock?
Yes. We regularly repin and rebuild original mortise locks in the Crestmoor and Rollingwood tracts. Rebuilding is usually cheaper than replacing a well-made original lock, and we will tell you honestly if replacement makes more sense.
Brands We Service in San Bruno
We work with the brands serious about security, and that matters in San Bruno, where one house might have an original Kwikset knob, a newer Schlage deadbolt, and a Medeco cylinder on the garage. Not all locksmiths speak Medeco or Abloy. We do. Our techs carry common pins, cylinders, and parts for Schlage and Kwikset, and we order high-security Medeco and Abloy components with fast turnaround. See our brands for the full roster of eight lock lines we service.
