Fast, Reliable Lock Installation & Rekey Across Kensington
Lock installation and rekeying in Kensington, CA typically runs $150-$450 depending on hardware grade, and most jobs are completed in a single trip when you hire a locksmith who knows the area. We’re Strongbox Lock & Safe Co. of California, and as a trusted Kensington Residential Locksmith, we’ve been serving local homeowners for over 42 years. We know the steep hillside lots, the original 1920s hardware still turning in Craftsman doors, and the fog that never quite lets west-facing deadbolts dry out. When you call (833) 294-4584, a live person answers - day, night, weekend, holiday - and we quote a flat price before the truck rolls. No bait, no switch, no callback queue.
Kensington isn’t like Berkeley or Richmond. It’s unincorporated Contra Costa County, governed by its own rules, policed by its own private force. That matters when you’re standing outside a locked door at dusk and need to know who to call. Our Lock Installation & Rekey team carries marine-grade lubricant for fog-seized cylinders, commercial-grade strikes for detached workshop doors, and the patience to rekey a skeleton-key mortise lock without damaging century-old woodwork. One trip. Done right. Backed in writing.
Why Strongbox Lock & Safe Co. of California Is Kensington’s Preferred Lock Installation & Rekey Company
We’ve earned our reputation in Kensington one job at a time - not through flashy ads, but by showing up when we say we will, quoting honest prices, and standing behind the work. Homeowners here remember the $19-locksmith scam that hit the East Bay years back. We are the alternative: background-checked, uniformed technicians who present ID at your door, flat pricing quoted on the phone, and a 90-Day Done Right Promise backed in writing with no paperwork, no arguing.
Our response time to Kensington averages 25-40 minutes from dispatch, depending on whether you’re up near Kensington Circle or down along Arlington where the Berkeley border blurs. We recently installed a heavy-duty Baldwin mortise lock and rekeyed four original skeleton-key cylinders on a 1920s Tudor Revival off Amherst Avenue. The owner’s detached workshop needed a reinforced strike plate and a commercial-grade Schlage deadbolt, so we called on our Commercial Locksmith in Kensington expertise and brought all hardware in a single trip - no running back for parts. That’s how we work in Kensington. We plan to be here in thirty years, so we act like it.
Our customers in Kensington tend to be long-time homeowners, many 55-75, who have been in their houses for decades and intend to stay. They don’t want the cheapest bid. They want the job done once, done right, and never thought about again. We honor a permanent 5% discount for seniors and veterans, and we never subcontract - every technician is our own employee, background-checked, wearing a Strongbox uniform.
Our Lock Installation & Rekey Services in Kensington
Smart Lock Installation
Smart locks on Kensington’s original mortise doors require more than a standard retrofit. The thick, often warped Douglas fir panels in 1920s-1940s bungalows don’t always accept modern deadbolt bore sizes without careful routing. We install Schlage Encode and Yale Assure models specifically selected for older door stock, preserving the exterior aesthetic while adding keypad and app access. For homeowners near Kensington Circle who want remote entry for caregivers or family, we configure Wi-Fi bridges that actually hold signal through the hills’ topology. Typical smart lock installation in Kensington runs $280-$520 including hardware and labor.

Keyless Entry
Keyless entry systems free Kensington homeowners from carrying keys on fog-damp morning walks to the Village. We install push-button mechanical locks for detached workshops and pool houses where power runs unreliable, plus electronic keypad systems wired to main entry doors. The marine layer here means every exterior installation gets sealed with dielectric grease and a weatherproof gasket - standard procedure for us, often skipped by cut-rate operators. A keyless entry install on a typical Kensington front door runs $220-$380.

Keypad Lock
Keypad locks suit rental properties and multi-generational homes common along Colusa and Arlington, where adult children or tenants need independent access. We program user codes, schedule automatic lockouts, and show you how to add or delete codes without calling us back. For the heavy sliding doors on hillside workshops - doors that standard residential hardware can’t handle - we source commercial-grade keypad deadbolts with reinforced strike boxes. These installs run $240-$420 depending on door prep and strike reinforcement needed.

Biometric Lock
Biometric locks bring fingerprint access to Kensington homes where keys get lost or where household staff need temporary, traceable entry. We install fingerprint-enabled Schlage and Medeco units rated for exterior marine exposure, calibrated to work reliably even when fingers are slightly damp from the persistent fog. These systems pair well with KPPD’s security-conscious homeowner base - biometric logs provide timestamped access records that complement private policing protocols. Biometric lock installation in Kensington typically runs $350-$580.

Trusted Brands We Service in Kensington
We stock and install Abloy, Schlage, Kwikset, and Medeco for Kensington customers, with common cylinders, strikes, and smart lock modules on our trucks. That means no waiting for parts from a warehouse across the Bay. For the original skeleton-key hardware still turning in Kensington’s Tudor Revivals, we maintain relationships with specialty suppliers who reproduce bit keys and mortise lock bodies. Whether you’re matching existing finish on a 1930s Spanish Colonial cottage or upgrading to a modern smart lock on a hillside Craftsman, we bring the right hardware in one trip - and if we don’t have it, we know exactly where to get it fast.
Common Lock Installation & Rekey Problems We See in Kensington Homes
- Corroded exterior cylinders from persistent fog. West-facing doors in the hills seize up within a year if not installed with marine-grade lubricant. We see this constantly on homes above Arlington where the marine layer sits heaviest. A standard dry lube application lasts six months here; we use dielectric grease and stainless-steel cylinders for longevity.
- Oversized workshop doors with mismatched hinges. Standard residential hardware can’t handle the weight of heavy sliding or barn-style doors on detached workshops, leading to sagging and misalignment. We install commercial-grade strikes and reinforced jamb plates spec’d for the actual door weight.
- KPPD dispatch delays when homeowners mistakenly give a Berkeley address. Kensington’s unincorporated status means lockout calls near the border - especially on Colusa and Arlington - require knowing which police agency responds. We always verify the exact address before advising which agency to call while waiting.
- Original mortise locksets with worn cams and missing skeleton keys. These require specialist knowledge to rekey without damaging irreplaceable cast-iron bodies. We carry bit-key blanks and have rebuilt cams on locks from the 1920s that homeowners were told were unfixable.

Seniors and veterans receive a permanent 5% discount. Call (833) 294-4584 for your exact quote - estimates are free, and we’re happy to talk through your specific door and hardware.

FAQs - Lock Installation & Rekey in Kensington
Yes, we install smart locks on original mortise doors in Kensington regularly, though it requires careful routing and often a custom mounting plate to preserve the door’s exterior appearance. The thick Douglas fir panels in 1920s Craftsman bungalows don’t accept standard bore sizes without modification, and we use Schlage and Yale units specifically selected for older door stock. We also configure Wi-Fi bridges to maintain signal through the hills. Call (833) 294-4584 for a free assessment of your specific door - estimates are free.
Persistent marine layer moisture from the Bay corrodes exterior cylinders on west- and north-facing doors in Kensington noticeably faster than in flatland cities like Richmond or Berkeley. Standard dry lubricants wash out within months here; we replace with stainless-steel cylinders and seal with dielectric grease as standard practice. If your deadbolt was installed without marine-grade prep, reinstallation with proper sealing typically runs $150-$220. Call (833) 294-4584 - we’ll diagnose over the phone and quote a flat price before rolling.
We verify your exact Kensington address before dispatch so we can advise correctly whether KPPD or Berkeley PD has jurisdiction, since the unincorporated boundary runs invisibly through streets like Colusa and Arlington. KPPD, the Kensington Police Protection District, is a private force - one of the only ones in California - and their dispatch protocols differ from municipal departments. We maintain direct contact numbers and know their coverage boundaries precisely. For emergency lockout response in Kensington, call (833) 294-4584 - we answer live, 24/7, and we’ll guide you on agency notification while our technician is en route.
Yes, we install commercial-grade keypad and keyless entry systems on heavy sliding and barn-style workshop doors throughout Kensington’s hillside properties, and as an Automotive Locksmith - Kensington specialist, we also handle vehicle lockouts and key programming for local drivers. Standard residential hardware fails on these doors due to weight and misalignment; we spec reinforced strikes and heavy-duty bolt mechanisms rated for the actual door mass. A typical workshop keyless install runs $240-$420 depending on strike reinforcement needed. We bring all hardware in one trip - no running back for parts. Call (833) 294-4584 for a flat quote.
Yes, we rekey original skeleton-key mortise locksets common in Kensington’s 1920s-1940s housing stock, including fabricating replacement bit keys when originals are lost. These cast-iron bodies require specialist knowledge to disassemble without cracking; we’ve rebuilt cams and sourced replacement springs for locks other locksmiths declared unfixable. Rekeying a skeleton-key lockset in Kensington typically runs $150-$240. Call (833) 294-4584 - we’ll ask a few questions about your specific lock and quote a firm price before we drive.
