Rekey Locks is the service Tamalpais Valley calls Cypress Lock & Key for most often, and the local terrain changes how we approach it. Homes in this valley sit on steep, fog-dampened lots, reachable by narrow lanes and wooden stairways, with doors that may be a 15-minute walk from the truck. We plan Tamalpais Valley jobs around that: gear packed for a hike, hardware chosen for marine-layer corrosion, and rekeys priced in a range that makes security after a move or turnover an easy decision. Call (877) 265-4385 for a quote that matches your actual door.
Why Tamalpais Valley Homes Are Different
Most of the housing here dates from the 1950s through the 1970s: California ranch and split-level homes with original single-cylinder deadbolts on wood-frame doors. Those locks have been absorbing Pacific fog and winter rain for fifty-plus years, and in the lower canyon pockets where the marine layer lingers, cylinders corrode and seize faster than homeowners expect. We regularly free up or replace rusted cylinders on doors facing the open ridges, and we recommend weather-resistant finishes for any new hardware.
The terrain is the other half of the story. Tamalpais Valley’s homes are packed into narrow canyon floors and hillside lots served by private lanes, shared drives, and long exterior stairways. A rekey job often starts with a gear check and a walk up a wood stairway through redwoods, not a curb pull-up. The same property may have a detached garage or a separate ADU with its own lock set, each needing its own keying decision. And because the valley sits close to Mount Tamalpais and the Golden Gate National Recreation Area, second homes and vacation rentals are common. Owners need quick rekeys after tenant turnovers and lock systems they can manage from a distance, which means we spend a lot of time on remote-access hardware that holds up to the damp.

Our Main Tamalpais Valley Services
Beyond rekeying, Tamalpais Valley homeowners call Cypress Lock & Key for two services more than any others: car key replacement and emergency lockout response. Each one has a dedicated local page with the full detail.
Car Key Replacement in Tamalpais Valley
A snapped or lost car key on a hillside lane is a different problem than one in a flat suburban driveway. There is no running down the block to a corner shop, and towing off Mount Tamalpais’s flanks is expensive and slow. We bring the programming equipment to the vehicle, cut and pair a new key on site, and handle the job without sending you to a dealership. That local fact matters when the nearest dealer is a winding drive away and your car is blocking a shared drive that three other homes use. Car Key Replacement in Tamalpais Valley

Emergency Locksmith in Tamalpais Valley
A lockout in Tamalpais Valley tends to happen at the worst possible access point: a fog-soaked stairway at 11 p.m., a back door behind a redwood that blocks every streetlight, or a gate latch that has finally seized shut. We know the lanes that are too narrow for a full-size van, so the technician arrives with the right tools in hand, not a truck that cannot get close. Emergency calls here are handled with real urgency, and we work the lock you already have, which usually means no damage to the door, frame, or hardware. Emergency Locksmith in Tamalpais Valley

Rekey Locks in Tamalpais Valley
Rekeying in Tamalpais Valley is the smartest security move after a tenant turnover, a relationship change, or years of copies floating around the neighborhood. Most homes here still run on original 1950s – 70s cylinders that were never rekeyed even once, and the damp has only made those tired locks easier to defeat over time. A rekey changes the internal pins so the old keys simply stop working, without the cost of replacing hardware that is still serviceable. It is the service we recommend most in this valley, and it protects budgets and security at the same time. For the full service breakdown, see Rekey Locks.
Lock Rekey
Signs you need it
You just moved, ended a relationship, or have no idea how many copies of your key are out there.
What it costs in Tamalpais Valley
Lock rekey in Tamalpais Valley typically runs $65 – $180 for the first lock, with each additional lock rekeyed to the same key at $15 – $40 per lock.
How we do it
We remove the cylinder, swap the internal pins to a new key code, and hand you fresh keys while the old ones stop working instantly.
Rekey Door Lock
Signs you need it
Your door lock turns hard in the winter damp, or a single key should have controlled access but does not.
What it costs in Tamalpais Valley
Rekeying a door lock in Tamalpais Valley falls between $65 and $180, with additional doors at $15 – $40 each when we rekey them all to one key.
How we do it
We test the lock’s condition first, clean or replace corroded parts if the marine layer has done damage, then rekey the cylinder so one key turns every door you choose.
What Rekey Locks Costs in Tamalpais Valley
| Item | Typical range in Tamalpais Valley |
|---|---|
| Rekey first lock (labor + pins) | $65 – $180 |
| Each additional lock keyed alike | $15 – $40 per lock |
| Rekey plus new deadbolt install (when cylinder is too corroded) | $110 – $260 |
How long does a rekey take in Tamalpais Valley?
Most residential rekeys in Tamalpais Valley take 30 – 60 minutes for two or three locks. The hike to the door is often the longest part of the job, so we schedule that time in and quote it upfront.
Do you have to replace my locks to change the keys?
No. Rekeying changes the internal pins so the old keys stop working, but keeps your existing hardware. It is the lower-cost option for most Tamalpais Valley homes. Full replacement only makes sense when hardware is corroded beyond repair or you want a visual upgrade.
Brands We Service in Tamalpais Valley
We work across eight lock brands, so a Tamalpais Valley home with a Baldwin entry set, a Mul-T-Lock deadbolt, or a Sargent commercial lock gets serviced by one technician, not three. Parts for the common residential lines are stocked on the van; high-security and premium lines we order or machine locally, with most turnarounds inside a couple of days.
