Emergency locksmith service in Larkspur typically runs $95 to $280 depending on the hour and the lock type, and most lockouts are resolved within 45 minutes of arrival. If you’re locked out of a Craftsman bungalow near Magnolia Avenue or a multi-tenant building off Doherty Drive, the fastest way to get back inside is to call (877) 265-4385. We’re Cypress Lock & Key, and we’ve been handling Larkspur lockouts long enough to know that every neighborhood here comes with its own quirks: original mortise locksets in the older homes, restricted key systems in newer apartment buildings, and a damp winter season that makes deadbolts bind at the worst possible moment.
This page explains how Larkspur’s settled historic storefronts and damp-weather door swelling create unique emergency lockout challenges, and how we solve them without damaging original hardware. If you need a locksmith in Larkspur right now, call (877) 265-4385. We answer around the clock.
Why Cypress Lock & Key Is Larkspur’s Preferred Emergency Locksmith Company
Larkspur isn’t a place where a generic locksmith works well. The housing stock along Magnolia Avenue, Madrone Avenue, and the steep side streets off Sir Francis Drake Boulevard includes early-20th-century bungalows and Craftsman-style homes, many of which still carry original mortise locksets and single-cylinder hardware from when the town was first built out. When a key snaps in a mortise lock or a deadbolt stops throwing, the repair isn’t a simple swap. It requires a tech who knows how to work on the lock that’s already in the door, without telling you to replace the whole thing. That’s exactly the work we do.
Noel Carver leads Cypress Lock & Key from our base in Oakland, and we work across eight lock brands: Schlage, Kwikset, Baldwin, Yale, Sargent, Medeco, Mul-T-Lock, and Abloy. For Larkspur homeowners and building managers, that breadth matters. A limited one-brand shop might suggest drilling and replacing. We can usually extract, rekey, or rebuild what you have, which saves the original hardware and a lot of money. Larkspur’s old-growth doors and custom millwork are not things you want to drill if you can avoid it.
We also don’t send you somewhere else for car keys. Our automotive key replacement covers most modern transponder and fob-programming jobs, which means a Larkspur resident with both a house lockout and a car key problem can handle both with one call. That’s not common in this trade.

Our Emergency Locksmith Services in Larkspur
24/7 Emergency Lockout
Lockouts happen at bad times. We answer the phone at 2 a.m. the same way we answer at noon. For a locked-out resident in Larkspur, the most important thing is that the person on the other end of the line knows the area and can get to it without wasted time. We serve both 94939 and 94977, from the flats near the ferry terminal up to the hillside neighborhoods above Baltimore Canyon. If you’re locked out of a house, apartment, or condo in Larkspur, call (877) 265-4385 and we’ll start heading your way.
We also take non-destructive entry seriously. Most Larkspur lockouts can be opened by picking or by using a bypass tool that doesn’t touch the door. For doors that do need drill work, we tell you before we start and give you the flat price up front.

Broken Key Extraction
Keys break in locks more often in Larkspur than in drier parts of Marin, because the moisture in the air and the salt from the nearby bay cause older key blanks to corrode and fatigue. We got a call from a tenant locked out of a second-floor condo on Magnolia Avenue after their key snapped in the original mortise lock. Our tech used non-destructive extraction, then rekeyed the lock cylinder with a Schlage pin and tumbler kit and adjusted the strike plate: the door had swelled from damp winter air and the deadbolt was binding. The resident was back inside in under an hour, and the freeholder’s historic door was left undamaged.
If your key breaks in a Larkspur door, don’t force the lock or try to fish the piece out with pliers. That’s how lock cylinders get ruined. Call us and we’ll extract the broken piece, cut a fresh key, and test the lock before we leave.

House Lockout
A house lockout in Larkspur is usually a different animal than an apartment lockout. The older single-family homes here, especially the bungalows built between 1900 and 1940, often have original lock hardware that’s been in place for eighty or ninety years. The lock still works, but the tolerances are tight and the strike plates have settled. We open these doors the same way we’d open a new one: slowly, with the least invasive method that works. That said, we’ve handled enough Larkspur house lockouts to know when a pick will do the job and when a deadbolt has to be removed from the inside.
The goal is always to get you back in and keep the door undamaged. If the door swelled or the frame shifted, we’ll tell you what adjustment the lock needs so it doesn’t happen again at 11 p.m. next winter.

Eviction Lock Change
For Larkspur landlords and property managers, an eviction lock change needs to be coordinated, documented, and done within a specific window. We work with freeholders and management companies across Larkspur, including buildings on Doherty Drive and in the smaller multi-unit blocks near the downtown core. The process is straightforward: we rekey or replace the cylinder, provide new keys, and confirm the old keys no longer operate the lock. Let us know if the building uses a restricted key system, because the new cylinder has to be matched to the building’s keyway. We’ll handle that on site.

Trusted Brands We Service in Larkspur
We service locks from eight brands spanning entry-level residential to high-security commercial lines: Baldwin, Sargent, Mul-T-Lock, and Abloy among them. That means we can work on the lock you already have in a Larkspur storefront or hillside home, not just the one we’d prefer to sell you. Our techs carry a rolling inventory of common pin kits, key blanks, and cylinder parts for most brands, so we can usually repair or rekey on the first visit. For high-security Mul-T-Lock and Abloy systems, we coordinate key control with the building owner or manager. No surprise hardware. No “you need a whole new lock” unless you actually do.
Common Emergency Locksmith Problems We See in Larkspur Homes
- Deadbolts that bind every winter: Larkspur sits in the sheltered Ross Valley, where damp winters cause wooden door frames and sills to swell. The strike plate moves a millimeter or two, and suddenly the deadbolt won’t throw. We adjust the plate and often file the lip of the strike, which fixes the binding without touching the original hardware.
- Settled storefront doors in the downtown core: The clay-rich soil under Larkspur’s historic district shifts seasonally. Doors that fit perfectly in September start to drag in February. We’ve fixed enough of these to know that a rekey is sometimes the smaller part of the job – the strike realignment is what actually makes the new key work.
- Keys snapped in original mortise locks: The Craftsman homes along Madrone and Magnolia often have original rim mortise locks with skeleton or bit keys. When those old keys snap, the piece that’s left in the lock usually has to be extracted without scarring the faceplate. We carry extraction kits for exactly this.
- Restricted keys in multi-tenant buildings: Larkspur has a surprising number of newer condo buildings and older apartment conversions with restricted key systems. Getting locked out of one of these isn’t a standard rekey job; the new key has to come from a locksmith who can duplicate the restricted blank. We can.
Pricing for Emergency Locksmith in Larkspur, CA
An emergency house lockout in Larkspur typically runs $125 to $240, depending on the hour and how involved the entry is. Broken key extraction adds $40 to $80 on top of the standard service call. A basic rekey for a single-cylinder deadbolt after a lockout runs $35 to $65 per cylinder, including new keys. If the door is settled or swollen and the strike plate needs to be adjusted, that’s usually $30 to $60 in additional labor. The total price is quoted on the phone before anyone is dispatched, and it’s the same number on the invoice. No dispatch fee that turns into a surprise on arrival. If a Larkspur job is going to require a specialty part, like a cylinder for a Mul-T-Lock or Abloy system, we’ll tell you before the work starts. Call (877) 265-4385 for an exact quote. Estimates are free.

FAQs – Emergency Locksmith in Larkspur
Yes. We extract broken keys from original mortise locks in Larkspur bungalows using non-destructive extraction tools, not drilling. We’ve done this on Craftsman homes around Madrone Avenue and on Magnolia Avenue condos with original hardware. The key pieces come out through the keyway, the cylinder stays intact, and we cut a fresh key on site. Call (877) 265-4385 and we’ll walk you through what to expect before we arrive.
The damp winter air in the Ross Valley swells wooden door frames and sills, which pushes the strike plate out of alignment and makes the deadbolt bind. This is a seasonal pattern we see every wet season across Larkspur, particularly in older townhomes and Craftsman-era houses with solid wood doors. The fix is usually an adjustment to the strike plate, sometimes a light planing of the door edge. We’ll diagnose it on site and tell you the cost before work begins. Call (877) 265-4385 for a free phone estimate.
Yes. We work with restricted key systems in Larkspur multi-tenant buildings, including buildings that use Mul-T-Lock and Abloy keyways. A lockout in one of these buildings is not a standard rekey; the replacement key has to be cut on a restricted blank, and only a locksmith with the right blanks and keying authority can do it. We coordinate with the building manager or freeholder to verify key control before cutting. Call (877) 265-4385 and have your building manager’s contact info ready if possible.
Rekeying changes the internal pins in the existing lock so the old key no longer works; replacing means new hardware. For most Larkspur storefronts, especially the older wood-framed doors along Magnolia Avenue, rekeying is the better call. It preserves the original hardware, it’s faster, and it costs less. A rekey in a Larkspur storefront typically runs $35 to $65 per cylinder. Replacement is only necessary when the lock itself is damaged or worn out. Call (877) 265-4385 and we’ll tell you which one makes sense for your door.
Yes. We handle after-hours emergency lockouts for Larkspur businesses on Magnolia Avenue and throughout the downtown core. Many of those storefronts have settled doors and original hardware that need a careful hand, not a drill. We’re familiar with the block: the wood-framed doors, the clay soil, the seasonal swelling. Call (877) 265-4385 and we’ll have someone headed your way, no matter the hour.
