Fast, Reliable Residential Locksmith Across San Anselmo
If you’re locked out of a 1920s Craftsman on Tunstead Avenue or need a deadbolt replaced on a hillside home off Butterfield Road, a residential locksmith in San Anselmo has to know the difference between a mortise lock from the Coolidge administration and a builder-grade Kwikset from 2015. That’s the reality of this town’s housing stock, and it’s why we carry both old-style mortise tools and modern high-security cylinders on every truck we send into San Anselmo. Our Residential Locksmith team gets to most San Anselmo addresses in 30 to 45 minutes, depending on where you are in relation to Sir Francis Drake Boulevard. Call (956) 275-7388 and you’ll get a written price before we dispatch anyone, not a vague range that grows when the tech arrives.
Why Ridley Locksmith & Security Is San Anselmo’s Preferred Residential Locksmith Company
San Anselmo is the kind of town where people notice an unmarked van parked outside a neighbor’s house. We know that, which is why every Ridley technician shows up in a marked vehicle, wearing a uniform, with a company ID and paperwork in hand. Run by Drew Kowalski as part of the Garrison Partners family, we’ve operated under The Garrison Standard since 2007. That standard is a written code every tech follows: a written price before any work begins, a written guarantee covering the repair for one full year, and a second visit at no charge if the repair fails inside that window. It’s called the 365-Day Done Right Promise. It isn’t a slogan on a website. It’s a document you get before we touch a single screw.
San Anselmo homeowners have told us they called us because a previous locksmith quoted one number on the phone and handed them an invoice for more. That doesn’t happen with our crew. The price we quote over the phone is the price on the invoice. If the work requires something we couldn’t see until we arrived, we stop, explain what changed, and get your approval in writing before proceeding. We’ve done lockouts near the San Anselmo Town Hall, rekeyed rentals in the Seminary area, and reinforced doors on Sleepy Hollow properties where the setback from the street makes security a bigger concern. You don’t need to take our word for any of this. Ask us for references from San Anselmo customers. We’ll provide them.
Apartment Locksmith in San Anselmo
Apartment Locksmith work in San Anselmo usually means one of two things: a landlord who needs a unit rekeyed between tenants, or a tenant who needs access restored and wants the property manager involved. Downtown San Anselmo has a concentrated mix of older apartment buildings along San Anselmo Avenue and side streets like Ross Avenue, many of which still use original hardware. Rekeying those units is straightforward: we change the internal pins inside the existing lock cylinder so the previous tenant’s key stops working, without replacing the hardware itself. That typically costs between $75 and $160 per lock in San Anselmo, depending on the cylinder type.
Rekeying Between Tenants
If you’re a property owner with a vacancy, we can rekey every unit on one trip. Landlords in San Anselmo often combine this with a keyed-alike setup so one master key opens all units, while each tenant gets a key that only opens their own door. We’ll give you a flat per-lock price before we start, and a written guarantee on the work for a full year.
Tenant Lockouts and Access
Lost your apartment key on Red Hill? We can get you back inside without damaging the door, provided you can verify residency with a lease, utility bill, or confirmation from the property owner. In San Anselmo, most apartments use either a rim cylinder on the door surface or a mortise lock set into the door edge. We handle both. A typical apartment lockout runs $95 to $180, non-destructive, and the price is confirmed before dispatch.
Lost Key Replacement in San Anselmo
Lost Key Replacement in San Anselmo usually means one of three scenarios: you’ve lost the only key to a house, you’ve lost a key and suspect it could fall into the wrong hands, or you’ve lost a key to a high-security lock that needs a special blank. For standard Schlage, Kwikset, or Yale locks, we can cut a new key from the lock itself in most cases. If you’re worried about security because the key was lost near your home, rekeying is the safer move, that changes the lock’s internal pins so the lost key no longer works. Rekeying typically runs $75 to $160 per lock, while cutting a single standard key is $8 to $20.
High-Security Key Replacement
If your San Anselmo home has Medeco, Mul-T-Lock, or Abloy cylinders, replacement keys require a special card that limits who can duplicate them. If you don’t have that card, we can still help, but the process may require replacing the cylinder and keying it to a new card. That’s a job we’ve done on higher-end properties in Viewpoint and the hills above downtown. We’ll explain your options and give you a written quote for each before we start.
What If You Lost a Key to a Mortise Lock?
Older San Anselmo homes with original mortise locks present a different challenge. We can often remove the cylinder, decode it, and cut a new key without disturbing the mortise body. If the cylinder is too worn, we replace the cylinder and cut fresh keys to match. This is standard work for our techs, not a specialty upcharge. Expect $120 to $240 for mortise cylinder replacement with two new keys.
Trusted Brands We Service in San Anselmo
We work on the hardware that actually shows up in San Anselmo homes. That means a lot of Kwikset and Baldwin on doors installed in the last twenty years, Yale on older apartments downtown, and Medeco on the higher-security properties up in the hills. We stock standard pins, springs, and cylinders for Kwikset and Yale on our trucks so a rekey doesn’t turn into a two-visit job. For Medeco and other high-security lines, we order key blanks and components through the manufacturer and can usually schedule the work within a business day or two. Wherever you are in San Anselmo, if your existing hardware is in good shape, keeping it and rekeying it is almost always cheaper than replacing it. We’ll tell you honestly when replacement is the better call, and we’ll put that recommendation in writing.
Common Residential Locksmith Problems We See in San Anselmo Homes
- Worn mortise lock springs in pre-1940 doors. San Anselmo’s Craftsman bungalows and early 20th-century homes frequently have original mortise locks that are still working, but with springs that have lost their tension. The symptom is a thumb-turn that spins without throwing the bolt. We repair these rather than replacing them with modern hardware that doesn’t fit the door prep.
- Sticking deadbolts on hillside homes. Homes on slopes near Butterfield Road or in the hills above downtown settle over time, and a settling door frame can push the deadbolt out of alignment. We adjust the strike plate or the door itself, rather than drilling a bigger hole and leaving the door compromised.
- Lost keys to high-security cylinders. San Anselmo has a meaningful number of homes with Medeco or Mul-T-Lock high-security cylinders, often installed after a break-in or as part of a smart-home upgrade. Losing the key card complicates duplication. We handle the process end-to-end, including re-registering the new card.
- Rekeying between tenants in older apartments. Downtown San Anselmo rental inventory turns over regularly, and landlords often need a same-day rekey so a new tenant can move in. The older rim and mortise cylinders in these buildings are quick work with the right tools; we get it done before the moving truck arrives.

FAQs About Residential Locksmith in San Anselmo
Yes. Non-destructive entry on older mortise locks is standard practice for our techs in San Anselmo, and in most cases we can open the door without drilling or replacing the original hardware. If the lock’s internal mechanism has failed, we can remove the mortise body, repair the worn component, and reinstall it in the same door, preserving the original look. That’s the right approach for Craftsman and bungalow doors where replacing the hardware would damage the wood. Call (956) 275-7388 and describe your lock; we’ll tell you what to expect.
Every tech arrives in a marked Ridley vehicle, wearing a uniform with the company name, and carrying a company ID with their name and photo. They’ll hand you a written price for the work before they start, and they’ll show you the guarantee document for your job. If any of those aren’t present at your door in San Anselmo, call our office at (956) 275-7388 and we’ll confirm the dispatch. We never send subcontractors, and we never use unmarked vans.
Rekeying is almost always the better option. We change the internal pins inside your existing lock so the lost key no longer works, which typically costs $75 to $160 per lock in San Anselmo. Replacement only makes sense if the lock itself is damaged or you want to upgrade to a different hardware finish or a high-security cylinder. We’ll look at the lock and give you a written quote for both options before you decide.
Yes. We install ANSI Grade 1 deadbolts from brands like Schlage and Medeco throughout San Anselmo, including on older doors that need retrofitting. A bump-resistant or hi-security cylinder upgrades the lock core and makes it far harder to pick or bump, while keeping the existing door and hardware intact. Installed cost for a Grade 1 deadbolt with a high-security cylinder runs $180 to $320 in most San Anselmo homes. Get a written quote by calling (956) 275-7388.
We do. Smart locks and keypad deadbolts work on many pre-1940 doors, provided the door prep can accommodate the new hardware. On some original Craftsman doors with narrow stiles, we may recommend a surface-mounted smart lock or a retrofitted mortise-compatible keypad. In San Anselmo, a standard smart deadbolt installation runs $220 to $400 including hardware, and we’ll confirm the written price before we start. Call (956) 275-7388 to talk through what fits your door.
