Rekeying locks is the service San Carlos homeowners call about most, and it’s usually tied to the city’s housing stock: original 1940s-to-1970s ranch homes and Eichler-influenced builds where locksets have been in service for decades. The mortise locks and older cylindrical hardware on these doors rarely match what’s on the shelf at a big-box store, and that’s where a San Carlos-specific rekey matters. Cypress Lock & Key has served San Carlos since 2017, working on the lock you already have rather than pushing a replacement. For a rekey quote, call (877) 265-4385.
Why San Carlos Homes Are Different
San Carlos is a small, affluent Peninsula suburb where most locksmith work happens on original mid-century ranch and Eichler-style homes in the flats and hillside custom homes west of El Camino Real. That matters because the hardware in those homes is not uniform. Many flats houses still carry builder-era mortise locks with non-standard backsets. A rekey or replacement often turns into a hardware-matching job rather than a straight cylinder swap – you match the existing mortise body, find the right cylinder length, and keep the original trim intact. Homeowners in San Carlos generally do not want a modern deadbolt slapped onto a 1950s door. They want the original hardware working again, with new keys.
The climate adds another layer. Mild, dry summers and wet winters with coastal fog push interior humidity swings that cause older hardware to seize and deadbolts to stick, especially in unheated garages and exterior doors on the foggy western hillsides. A lock that turns fine in September can bind by January. Most of the rekeys we do in San Carlos include cleaning and lubricating the existing mechanism, not just swapping pins. And because this city is tightly built out and heavily owner-occupied, most customers want discreet, appointment-based service rather than an emergency truck idling in the driveway. The work is quieter, more deliberate, and focused on preserving what’s already there.
Styles & brands we work with
Our Main San Carlos Services
Beyond rekeying, two services dominate calls in San Carlos: car key replacement and emergency lockout response. Both have dedicated San Carlos pages, but here’s the short version of how each works here.
Car Key Replacement in San Carlos
San Carlos drivers park in tight driveways and garages carved into hillsides, and when a key snaps or a transponder stops reading, the nearest dealership is not always convenient. Car key replacement here means cutting and programming on-site, often for European and Asian makes that dealerships quote at $300-plus and schedule days out. Cypress Lock & Key carries key blanks and programming equipment for most makes, and we come to the vehicle. Full details on Car Key Replacement in San Carlos.
Emergency Locksmith in San Carlos
Lockouts in San Carlos happen at odd hours – a side gate off Alameda de las Pulgas, a back door that deadbolted itself, a garage with a stuck handle on a foggy night. Emergency response here means a technician who arrives with a working van stocked for older hardware, not just a drill. We get the door open first, then talk about whether the lock is worth saving. See Emergency Locksmith in San Carlos for response details.

Rekey Locks in San Carlos
Rekeying in San Carlos usually starts with a simple need: a new owner took possession of a 1950s ranch on a tree-lined street off Brittan Avenue, or a tenant moved out of a hillside rental west of El Camino Real, and the old keys are still floating around. Because so much of the city’s housing stock predates standardized modern locksets, rekeying here is less about swapping hardware and more about reconfiguring the lock that’s already in the door. We rekey mortise cylinders, older Schlage and Kwikset cylindrical locks, and premium hardware from Baldwin and Yale; we don’t replace what’s working. The full scope is on our Rekey Locks page.
Lock Rekey
Signs you need it
You’ve moved into a home in San Carlos, a key has gone missing, or you cannot account for every copy ever made.
What it costs in San Carlos
A standard lock rekey in San Carlos runs $18 to $30 per lock, plus a service fee of $65 to $85, and most homes require two to four locks rekeyed (figure $101 to $205 total for the typical three-lock house).
How we do it
We disassemble the cylinder, replace the pins so old keys no longer turn, cut a new set of keys, test every lock, and leave the original hardware in place.
Rekey Service
Signs you need it
You want every exterior lock in your San Carlos home to work from one key, or you want to invalidate copies given to a contractor, cleaner, or previous owner.
What it costs in San Carlos
A full rekey service, where all entry doors are rekeyed alike and one key operates everything, matches the same structure: $18 to $30 per lock plus a $65 to $85 service call, so a four-lock home in San Carlos lands around $137 to $205.
How we do it
We rekey each cylinder to a shared key code, cut one key that operates every rekeyed lock, confirm each deadbolt throws smoothly, and note any lock that’s too far gone to rekey reliably.
Keyed Alike
Signs you need it
Your front door, back door, and side gate in San Carlos each take a different key and you’re tired of juggling three copies.
What it costs in San Carlos
Keyed-alike service has no separate premium beyond the per-lock rekey rate ($18 to $30 per lock); the standard service fee of $65 to $85 applies, so three locks keyed alike run $119 to $175.
How we do it
We set all cylinders to one keying, rekey each lock, test the single key through every door, and hand you the number of copies you need.
What Rekey Locks Costs in San Carlos
| Item | Typical range in San Carlos |
|---|---|
| Standard service call | $65 to $85 |
| Rekey per lock | $18 to $30 |
| Three-lock home rekey (typical) | $119 to $175 |
Do you need to replace the locks when you rekey?
No. Rekeying keeps the existing hardware and changes the pins inside so old keys stop working. In San Carlos, where many homes have original mortise or older cylindrical locksets worth preserving, rekeying is usually the better and cheaper option.
How long does a rekey take in San Carlos?
Most San Carlos homes – two to four entry locks – are rekeyed in 45 to 90 minutes on site. Older mortise locks may add time if the cylinder is seized from fog-season moisture, but we carry the parts to address that on the same visit. Call (877) 265-4385 for a specific quote.
Brands We Service in San Carlos
We work on eight lock brands in San Carlos, from the builder-grade Schlage and Kwikset found on most mid-century ranch doors to premium Baldwin and Yale hardware and high-security lines from Medeco, Mul-T-Lock, Sargent, and Abloy. We stock common cylinders and key blanks in the van, so most rekeys and repairs finish on the first visit. For details, see our brands.

In San Carlos, the two biggest price drivers are hardware age and non-standard backsets. An original mortise lock on a 1950s flats home takes more bench time than a modern cylindrical swap, and a hillside house with three or four entry points simply has more locks in the rekey count. You’ll get the full price on the phone before anyone is dispatched, and that’s the price on the invoice – no surprise add-ons when the van pulls up.

What San Carlos Customers Say
"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"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."
— Allen Chen
