Rekey Locks is the service San Carlos homeowners call us for most, and the reason is simple: this city has a huge stock of mid-century homes where original locks have been patched and re-keyed for decades but the hardware itself was never replaced. Add in wet Peninsula winters that swell wooden doors and shift lock alignment, and you get a very specific kind of locksmith work. Citadel Locksmith has served San Carlos since 2011, and we carry the full range of hardware needed to make vintage doors secure again. Call (833) 589-8078 for a free estimate.
Why San Carlos Homes Are Different
San Carlos is a city of 1940s and 1950s single-family homes on narrow lots, running from the flat grid of streets near Laurel Street up toward the Elks Club and down toward Burton Park. The locks on these homes tell a story. Original mortise locksets, single-cylinder deadbolts, and hollow-core slab doors were common when most of this housing was built. Decades later, many of those locks are still in place, re-keyed again and again after tenants moved out, roommates left, or a cleaning service lost a key.
The climate here creates predictable seasonal call patterns. From November to March, San Carlos gets real rain that swells wood-frame doors and throws strike plates out of alignment. Summer brings the opposite: dry air, vacation re-keys, and mailbox lock replacements. Technicians working in 94070 need to know how to repair a 1960s cylindrical lockset in place, not just swap it for whatever is on the truck. In our experience, most of these older locks can be re-keyed and tuned to work like new, but when the internal components are finally worn past the point of repair, we install modern ANSI deadbolts and advise on the “peephole-plus-thumb-turn” upgrade that gives older front doors real security without a full door replacement.
Styles & brands we work with
Our Main San Carlos Services
Two services generate most of our calls in San Carlos. Below is what each involves here, with links to our dedicated pages for the full breakdown.
Car Key Replacement in San Carlos
Losing a car key on the Peninsula is a specific kind of headache. San Carlos has no dealership row, so getting a replacement car key often means driving to Redwood City or beyond, paying dealer pricing, and waiting days. We handle car key replacement for most makes at a fraction of dealer cost, usually same day. If you live near Burton Park or commute up 101, a missing transponder key doesn’t have to wreck your week. See Car Key Replacement in San Carlos for what we cover and what it costs.
Emergency Locksmith in San Carlos
A lockout at midnight on the west side of El Camino Real needs someone who actually answers the phone. Our emergency locksmith service covers San Carlos around the clock, and the work here often involves older doors that need a gentler touch than a drill. Whether it’s a balky night latch on a 1950s front door or a deadbolt that snapped its tailpiece, we get you back inside without destroying the hardware. Full details are on our Emergency Locksmith in San Carlos page.

Rekey Locks in San Carlos
Rekeying in San Carlos is the fastest way to take back control of who holds a key. Most homes here still carry original mortise or early cylindrical locks from the 1940s through 1960s, and those locks have usually been re-keyed many times over the decades. The wet winters add a second problem: swollen wooden doors that make even a properly re-keyed lock feel broken. We rekey the cylinder so old keys stop working, then adjust the strike plate and hinge alignment so the door actually latches cleanly. For the full scope of this service, see our Rekey Locks page.
Lock Rekey
Signs you need it
You have no idea how many keys are floating around for your front door, or you just moved into a San Carlos home and the previous owner’s keys are still out there.
What it costs in San Carlos
Rekeying a standard door lock in San Carlos typically runs $65 to $120 per cylinder, depending on brand and whether it’s a mortise or cylindrical lock.
How we do it
We disassemble the cylinder, swap the pins to match a new key, reassemble it, and test the lock repeatedly, then adjust the strike plate if the door has shifted with the season.
Rekey Door Lock

How much does rekeying cost in San Carlos?
Most San Carlos homes cost $65 to $120 per cylinder to rekey, so a typical front and back door job runs $130 to $240. High-security cylinders and mortise locks run higher. Call (833) 589-8078 for an exact quote, free.
Is a rekey enough for an older San Carlos door?
Usually yes, if the cylinder is still mechanically sound. When a 1950s lock has worn internals or a door has swollen badly, we’ll tell you before we start. We don’t sell replacements you don’t need.

Two things push prices up in San Carlos specifically. First, mortise locks on pre-1970s homes take longer to service than a modern cylindrical deadbolt. Second, rain-swollen doors often need strike plate and hinge adjustment before a rekey will actually function. We quote the full price on the phone before anyone rolls out, and that is the price on the invoice. No dispatch fee surprises.

What San Carlos Customers Say
"Programmed a transponder key for a 2014 model that the dealership wanted an absurd amount for. Same key, fraction of the price, took him twenty minutes in my driveway."
— Grace Lin"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
