Rekeying locks in Half Moon Bay solves a problem this town knows well: weekend homes that change hands or renters, family transitions, and keys that have floated around longer than anyone can track. The work here often means rehabbing hardware that coastal fog and salt air have been working on for years. Cypress Lock & Key has served Half Moon Bay since 2017, and we deal with this particular mix of security and corrosion every week. Call (877) 265-4385 for a rekey quote, a brand question, or an urgent lockout.
Why Half Moon Bay Homes Are Different
Half Moon Bay’s housing stock runs from mid-century cottages along the coastal bench to newer developments up on the hillside, and the older homes often still carry their original mortise locks or builder-grade Kwikset knobs. Up here, the persistent fog and salt spray work on exterior hardware year-round, and we see a pattern that’s distinctive to this stretch of coast: the locks on the ocean side of a house will seize up while the inland-facing ones work fine. West of Highway 1, especially around Miramar and the streets near the bluffs, that salt air gets into every hinge, deadbolt, and cylinder. A lock that’s been sticky for months will finally refuse to turn on a damp winter evening, and that’s when we get the call. The practical takeaway is that Half Moon Bay locks need more regular lubrication and more frequent hardware replacement than the same brands would in a drier climate. Marine-grade lubricant and stainless hardware are the tools that actually keep things working here, and we keep both stocked.
The other half of the equation is the weekend-home reality. Half Moon Bay has a steady current of Bay Area visitors and part-time residents, and lockouts at rental properties and second homes make up a meaningful share of our work. A family drives over from the East Bay on a Friday night, the key code doesn’t work, and nobody’s nearby with a spare. We handle those calls regularly.
Styles & brands we work with







Our Main Half Moon Bay Services
Most Half Moon Bay homeowners call us for two things: getting back into a vehicle when a key breaks or disappears, and handling after-hours lockouts at homes and rentals. Both are jobs where being local matters more than most people expect.
Car Key Replacement in Half Moon Bay
Car key replacement on the coast often means a transponder key that’s been sitting in a salty pocket or a fob that took a swim in the ocean. We program and cut keys for most makes right here in Half Moon Bay, which saves you the drive to a dealership over the hill. Whether you’re at Surfer’s Beach, stuck in the Safeway parking lot, or parked up near the distillery, we come to you. Read more on our Car Key Replacement in Half Moon Bay page.

Emergency Locksmith in Half Moon Bay
Half Moon Bay’s small size means limited after-hours options, so when a renter locks themselves out of a cottage in Miramar at 9 p.m. or a homeowner can’t get the deadbolt to retract on a February night, we’re the call. Emergency locksmith response here is about getting to you without a two-hour wait and without making the lock worse. See Emergency Locksmith in Half Moon Bay for how our emergency calls work.

Rekey Locks in Half Moon Bay
Rekeying locks in Half Moon Bay means changing the internal pins so old keys stop working and a new key takes over. It’s the right job when a house changes hands, when a caretaker or cleaner’s key set needs tightening up, or when a key has gone missing and replacing every piece of hardware feels wasteful. We rekey Schlage, Kwikset, Baldwin, Yale, and the rest of the locks we service, and for older coastal homes with original mortise locks, we can often rekey the existing cylinders instead of replacing them. If you’re moving into an older Half Moon Bay place where the same key may have been circulating for decades, a rekey is the most cost-effective security reset available.
Lock Rekey
Signs you need it
You’ve just closed on a home, an employee or tenant left, or you have a key floating around that you can’t account for.
What it costs in Half Moon Bay
A standard lock rekey in Half Moon Bay typically runs $75 to $160 per lock, with the per-lock rate dropping as you add more.
How we do it
We remove the cylinder, swap the pins to match a new key, and reinstall everything so the old keys stop turning.
Rekey Door Lock
Signs you need it
A door lock has been giving trusted neighbors, cleaners, or contractors access for years, and you want a clean slate without new hardware.
What it costs in Half Moon Bay
Rekeying a door lock runs $75 to $160 per lock, and we can key every exterior door to one key for a consistent setup.
How we do it
We rekey the cylinder in place or at the bench, then test the new key and the old key to confirm the old one is dead.
Keyed Alike
Signs you need it
You carry a ring with four different keys for four doors, and you’d rather have one key for the whole house.
What it costs in Half Moon Bay
Keyed-alike service costs the same per lock as a standard rekey, $75 to $160 per lock, and often saves money because we don’t replace any hardware.
How we do it
We pin every lock you want unified to the same key, whether it’s a front door deadbolt, a side door knob, or a garage entry.
What Rekey Locks Costs in Half Moon Bay
| Item | Typical range in Half Moon Bay |
|---|---|
| Rekey a single lock | $75 – $160 |
| Rekey multiple locks (per lock) | $65 – $140 |
| Service call / trip charge | $35 – $65 |
Is it cheaper to rekey or replace locks in Half Moon Bay?
Rekeying is almost always cheaper, because you keep the existing hardware. We change the pins inside the cylinder, not the lock itself, so $75 to $160 per lock covers most Half Moon Bay jobs. Call (877) 265-4385 for a firm quote.
Can you rekey locks at a rental property in Half Moon Bay?
Yes, and we do this regularly between tenants. We rekey every exterior lock to a new key so the previous tenant’s copies stop working, usually in one visit. Call (877) 265-4385 to schedule a rekey between turnovers.
Brands We Service in Half Moon Bay
We work on the lock you already have, which matters in Half Moon Bay where homes span decades of hardware. Schlage, Kwikset, Baldwin, and Yale cover most of the residential work, and we service Mul-T-Lock and Sargent for property managers and small businesses that need commercial-grade or high-security hardware. We keep common pins, cylinders, and replacement parts for these brands in stock, which means most jobs finish same-day. See our brands for more detail.

FAQs About Locksmith in Half Moon Bay
For emergencies, we aim to reach most of Half Moon Bay quickly, since we’re based on the coast side rather than coming over from San Mateo. Non-urgent jobs like rekeys are scheduled at a time that fits you. Call (877) 265-4385 for a real arrival window.
Most single-family homes in Half Moon Bay don’t require approval for a rekey or lock change, since the work is internal to the lock. Some HOAs, like Ocean Colony, may have rules about visible hardware finishes, so check if you’re changing hardware rather than rekeying. Rekeying keeps the same hardware, which sidesteps most approval issues.
It does, especially west of Highway 1. Salt and fog creep into cylinders and deadbolts, and we see the ocean-side locks fail first. We use marine-grade lubricant and stainless components to slow it down. If your lock is stiff, call (877) 265-4385 before it fails completely.

What Half Moon Bay Customers Say
"Quoted a price on the phone and honored it. After the last locksmith I called, that alone is worth a review."
— Sarah Vaughn"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
