Rekeying locks is the most common locksmith job we handle in Marin City, and for good reason. This unincorporated pocket of southern Marin is defined by dense apartment complexes, townhouse clusters, and hillside homes built mostly in the 1940s and 1950s, which means turnover drives constant rekey cycles and property managers need coordinated service across multiple units in a single visit. The damp, fog-heavy air off Richardson Bay also accelerates corrosion on older mortise locks and builder-grade hardware, so the work here leans toward careful mechanical restoration rather than quick fixes. If you need a locksmith in Marin City, call Citadel Locksmith at (833) 589-8078.
Why Marin City Homes Are Different
Marin City’s housing stock tells a specific story. Built largely as defense and shipyard worker housing during and after World War II, the community is dominated by mid-century apartment buildings and townhome complexes packed into a compact valley between Sausalito and Mill Valley. That means a high concentration of shared-entry doors, unit locks, and original mortise or builder-grade hardware that has now seen seventy-plus years of coastal weather. When we rekey a door in Marin City, we’re usually working on hardware that needs lubrication, hinge adjustment, or strike-plate realignment before a fresh key even matters.
The climate compounds the wear. Marin City sits low and close to the bay, catching fog that rolls through the Golden Gate and lingers well into the morning. Exterior locks, deadbolts, and door hardware here corrode faster than in the drier inland towns of Marin. We stock rust-resistant replacement parts and weather-appropriate lubricants specifically for this environment. Property managers working across multiple buildings in the 94965 ZIP code tell us the same thing: they’d rather have one locksmith who understands the aging hardware and can rekey a dozen units on a schedule, than chase bids from a dozen different providers.

Rekey Locks in Marin City
In Marin City, rekeying is rarely a simple “new tenant, new key” transaction. The housing stock is old, the hardware is often original to the building, and the marine air has been working against the lock internals for decades. We rekey locks constantly across the 94965 ZIP code, and the job almost always involves a careful assessment of the cylinder, the door alignment, and the likelihood of future corrosion before we cut a single new key. Rekeying is the fastest way to take back control of who holds a key, and in a community with this much rental turnover, it’s also the most practical. Our Rekey Locks service covers everything from single-unit jobs to full-building rekeys for property managers who need coordinated scheduling.
Lock Rekey
Signs you need it
You’ve moved into a new unit in Marin City, ended a lease, lost track of spare keys, or recently experienced a break-in.
What it costs in Marin City
Lock rekeying in Marin City typically runs $75 to $160 for the first lock and $25 to $45 per additional lock rekeyed in the same visit.
How we do it
We remove the cylinder, replace the internal pins so the old key no longer works, and cut new keys to fit the new configuration.
Rekey Door Lock
Signs you need it
A roommate has moved out, a contractor still has a key from a recent job, or you can’t account for every spare key floating around the building.
What it costs in Marin City
Rekeying a door lock runs $75 to $160 for the first cylinder in Marin City, with additional cylinders in the same call running $25 to $45 each.
How we do it
We match the new pins to your existing key or a new one, test the lock in place, and confirm the old key no longer turns the cylinder.
Keyed Alike
Signs you need it
You’re carrying four different keys for your Marin City unit, the shared entry door, a storage closet, and a mailbox, and you’d rather carry one.
What it costs in Marin City
Setting multiple locks to one key in Marin City typically runs $75 to $160 for the first lock, plus $25 to $45 per additional lock keyed alike.
How we do it
We repin each cylinder to the same key profile, then test every lock with the single key before we call the job done.

What Marin City Customers Say
"Locked out at eleven at night with a kid asleep in the car. He was there in 25 minutes, had the door open in under two, and did not do the thing where the price goes up once he's standing in front of you."
— Greg Lawson"Told me over the phone that what I needed was a five dollar part from the hardware store, not a locksmith. I called him back a month later for real work because of that."
— Yolanda Mendoza"Key snapped off in the deadbolt. He extracted it without damaging the cylinder, which I did not think was going to be possible."
— Oscar Reyes
