Home Rekey & Lock Change

Every time a key leaves your control — through a move, a lost set, a breakup, a former houseguest, or a contractor who kept a copy — your lock becomes a liability. The physical hardware on your door may look the same, but the key map inside the cylinder is now known to someone you didn't choose. A professional rekey lock service reorganizes the internal pin tumblers so that all previous keys are instantly voided and a fresh set works exclusively. It's the most direct way to close that gap without replacing the entire lockset. For situations where the hardware itself is damaged, outdated, worn, or simply not up to the security standard you want, a full lock change service — swapping the entire lockset — is the right call. Our technicians will walk you through which option fits your specific door, lock brand, and situation before any work begins.

San Rafael's housing stock is genuinely diverse: Victorian-era homes near B Street have original mortise lock bodies built into the door stile, mid-century ranches in Terra Linda carry standard cylindrical knobsets, and newer developments along the waterfront use electronic or smart-lock systems with programmable codes. Our team is familiar with all of it. We stock Schlage, Kwikset, and a range of mortise lock cylinders and bodies so we can complete most jobs in a single visit — no back-ordering parts, no leaving your door unsecured overnight.

The mortise lock is one of the most durable and tamper-resistant lock types available, and it's also one of the most misunderstood. Found in many older San Rafael homes and in upscale commercial properties alike, a mortise lock sits inside a pocket (the mortise) cut into the door edge, giving it far more contact with the door structure than a standard cylindrical lock. When a mortise lock needs rekeying or replacement, it requires a technician who understands the internal lever or pin mechanism, the cam, the tailpiece, and the specific profile of the cylinder — details that matter enormously when you're trying to keep a door genuinely secure. Our technicians work with mortise lock hardware regularly and carry the specialty tooling to service them correctly.

Beyond mortise systems, we handle door knob lock replacements, single and double-cylinder deadbolts, lever-handle locks, rim locks, multipoint locking systems, and electronic keypad or smart locks. If you have a Defiant lock and need to update the code after a move, or a Honeywell door lock where the access code needs to be changed for a new household, we can walk you through a factory reset and new-code programming on-site — or replace the unit entirely if the hardware has reached the end of its useful life. Need to update a Master Lock combination on an outbuilding or storage unit? That's part of what we do. Call (415) 237-9558 any time — we answer 24/7 and can typically have a technician en route to your San Rafael location within the hour.

The window between moving in and truly knowing who has access to your home is one of the riskiest periods in homeownership or renting. Former tenants, property managers, neighbors, and maintenance workers may all hold copies of the existing keys — and in a city like San Rafael, where rental turnover in neighborhoods like Glenwood and the Canal District can be high, this is a real and common concern. A move-in rekey should happen before you unpack, not after. Our mobile team can meet you at the property the same day, even if that day is a Sunday evening or a holiday morning. We verify ownership or tenancy documentation as part of our process — a step that protects both you and the integrity of the service — and then complete the rekey or door lock change with minimal disruption to your move.

Lost keys create a similar urgency. If your keys are missing rather than simply misplaced, you don't know where they are or who might find them with your address attached. That's a reason to treat it as an emergency locksmith situation rather than a wait-and-see. Our 24/7 availability means you're never stuck waiting until Monday morning for protection you need right now. The cost of a service call depends on several factors — the type of lock, the number of doors, the time of day, travel distance to your address, and whether replacement parts are needed — but we confirm an exact, up-front price before any work starts. No surprises on the invoice.

Security needs in a commercial setting are layered in ways that residential jobs rarely are. A retail shop on Fourth Street, a medical office near Kaiser San Rafael, or a warehouse in the East San Rafael industrial corridor may have multiple entry points, different access levels for different staff, and hardware that needs to meet both functional and code-compliance requirements. Our commercial locksmith work includes master key system design, commercial-grade mortise lock installation and rekeying, exit device (panic bar) servicing, keypad and access-control integration, and high-security cylinder upgrades. When an employee leaves — whether on good terms or not — a commercial lock change or targeted rekey is the fastest way to secure the business without disrupting the entire key system.

We understand that business owners can't always plan for security events during business hours. A break-in attempt, a terminated employee, or a lost key fob at 11 p.m. is still an emergency, and our 24/7 mobile dispatch means a skilled technician can respond to your commercial property any time. We bring professional-grade hardware and the experience to install it correctly the first time. For San Rafael businesses that want ongoing key control — including the ability to add or remove access for staff without rekeying every lock each time — we can design and install a master key or restricted keyway system during the initial appointment. Reach us at (415) 237-9558 to discuss your commercial security needs and get a clear, honest quote before we begin.
