Fast, Reliable Lock Installation & Rekey Across Danville
Lock installation and rekeying in Danville, CA typically runs $25-$45 per cylinder for a standard rekey, $85-$180 for a new deadbolt install, and $150-$350 for a smart lock on an existing door prep. Most Danville jobs are done same-day or next-day, and every price is quoted in writing before we dispatch anyone. If you’re in Danville and need a lock rekeyed after closing on a home, or a smart lock installed on an original 1980s door, call (331) 310-8471 and a live person answers.
We work Danville differently than a volume locksmith would. The homes here are older than the surrounding valley in specific ways, and the hardware requirements in Blackhawk don’t match what you’d spec in San Ramon. We stock what Danville doors actually need, and we document everything.
Why Novak Lock & Security Is Danville’s Preferred Lock Installation & Rekey Company
Novak Lock & Security has been doing Lock Installation & Rekey work across the San Francisco Bay Area since 2002, and our Danville jobs skew toward a specific profile: homes built during the 1970s-1990s valley boom that still carry original builder-grade hardware, plus a steady stream of Blackhawk estates where the spec is Grade 1 or nothing. We know the difference between a Kwikset that can be rekeyed in ten minutes and a worn mortise cylinder that needs full replacement before a home sale. That distinction saves Danville homeowners real money.
Every Danville job is handled by a background-checked, uniformed technician working under The Haven Standard. The dispatcher quotes a firm price on the phone, and the technician is not permitted to change it at the door. This rule has been in place since 2002. It’s Haven Standard Clause 1: the price on the phone is the price on the invoice. No call-out surcharge added on arrival, no re-quoting after the hardware is opened up.
Daniel Novak founded the company on that single rule, and it’s still the operating principle today. Every visit ends with a documented photo record of the work, left with you before the tech drives off. Not as an upgrade. As a procedure.
Our Lock Installation & Rekey Services in Danville

Smart Lock Installation
Smart lock installation in Danville is most often a retrofit onto an existing deadbolt prep, and that’s where the trouble shows up. Original doors from the 1980s valley build-out have warped and sagged enough over 30-50 years that a new smart lock’s deadbolt throw binds against the strike plate. We don’t just mount the lock; we check the frame alignment, adjust or replace the strike plate, and test the throw under both open and closed conditions before we call the job done. If your door is in Blackhawk or any of the custom enclaves with thicker solid-core doors, we’ll spec the right tailpiece length and faceplate so the lock sits flush and operates without grinding. Most smart lock installations in Danville run $150-$350 depending on the lock model and prep condition.

Keyless Entry and Keypad Lock Installation
Keypad locks are the most common upgrade we install for Danville homeowners who host cleaners, dog walkers, or contractors and don’t want to hand out physical keys. On a standard prep, the job takes under an hour. On an older mortise door or a custom entry with a non-standard prep, we may need to install a surface-mount or a new deadbolt above the existing hardware. Keypad lock installation in Danville typically runs $120-$280. If you’re replacing a builder-grade keyed knob with a keypad deadbolt, we’ll also rekey or replace the lower knob so you don’t carry two separate keys for one door.

Biometric Lock Installation
Biometric lock installation in Danville shows up most often in Blackhawk and custom estates where homeowners want fingerprint entry without a phone, a fob, or a key. These locks need a stable door: if the frame moves seasonally, the bolt misaligns and the fingerprint reader gets blamed for what’s actually a carpentry issue. We check the door slab, hinges, and strike plate alignment before mounting the lock, then enroll your prints and test every enrolled finger at least twice. Plan on $200-$450 for a quality biometric deadbolt installed on a sound prep. If your door needs prep work, we’ll quote that separately and in writing before we start.

Key Duplication and High-Security Key Control
Key duplication in Danville splits into two markets. For standard Schlage or Kwikset keys, we cut duplicates on-site in minutes. For Medeco, Mul-T-Lock, or other restricted keyways common in Blackhawk, duplication requires the original key control card and a factory-authorized process. We’re factory-authorized for Medeco, Mul-T-Lock, Abloy, Baldwin, and Schlage, which means we can cut and issue high-security keys with full documentation. Standard duplicate keys run $4-$8 per key; restricted high-security duplicates run $15-$35 per key depending on the cylinder system.

Trusted Brands We Service in Danville
We stock and service the full spectrum of hardware Danville homes actually carry: entry-grade Kwikset and Schlage for quick rekeys and rentals, Baldwin for finish-matched estate hardware, and Medeco, Mul-T-Lock, and Abloy for high-security cylinders in Blackhawk. We keep common Schlage and Kwikset parts on the van for same-day Danville jobs, and we order Baldwin finish plates and Medeco cylinders with next-day availability when a spec is unusual. For smart lock work, we interface regularly with Lutron, Control4, and Ring ecosystems, and we’ll coordinate with your integrator if the project calls for it.
Common Lock Installation & Rekey Problems We See in Danville Homes

These are the issues we document on Danville jobs more than anywhere else in the valley:
- Deadbolt binds every fall and spring. Danville’s position below Mount Diablo means hot, dry summers followed by wet winters. Wooden door frames on the area’s many ranch and two-story homes swell in winter and shrink in summer. The deadbolt throw misaligns with the strike plate, and the lock feels broken. Rekeying won’t fix the alignment. The fix is strike plate adjustment or a larger plate, sometimes a hinge tune-up. We check all of it before we sell a new lock.
- Builder-grade pin-tumbler deadbolts from the 1980s are worn past reliable rekeying. A cylinder with 35-40 years of key insertions and weather exposure develops enough slop that new pins don’t seat cleanly. If we rekey a cylinder and the key sticks or the plug wobbles, we’ll tell you and quote a replacement instead of handing back a marginal lock. Honest call, every time.
- Mortise locks on Blackhawk-era customs with mismatched aftermarket work. Many custom estates in Danville carry mortise locksets with non-standard body dimensions. If a previous handyman rekeyed one with a generic pin kit and didn’t match the high-security key control expected at sale, we do a documented audit and replace the cylinder properly. This matters for real estate transfers where the buyer’s agent is checking the hardware.
- Smart lock retrofits on warped or sagging doors. A smart lock’s motorized deadbolt has less tolerance for misalignment than a manual throw. If the door sags, the smart lock jams, drains batteries, and eventually strips the internal gear. We check the slab and frame before we mount anything, and we’ll tell you if the door itself needs attention first.

FAQs - Lock Installation & Rekey in Danville

Yes, in most cases. Original mortise cylinders from that era can be rekeyed if the cylinder body and plug are still sound. If the cylinder has been rekeyed multiple times, has worn keyway tolerances, or carries mismatched aftermarket pins, we’ll recommend a replacement cylinder instead. We’ll show you the wear before we recommend spending money. Rekeying a mortise cylinder in Danville typically runs $30-$50 per cylinder. Call (331) 310-8471 and we’ll tell you if a rekey or a replacement makes sense for your specific lock.
Yes. We regularly perform full hardware audits for Blackhawk estate sales where the buyer’s agent needs documented key control, matching finishes across all entry points, and high-security cylinder paperwork. We were called to a custom estate in Blackhawk after a sale, where the front entry had an oversized solid-core door with a non-standard mortise lock and a misaligned strike plate from seasonal frame swelling. Our tech documented the existing cylinder, rekeyed the active pin-and-tumbler deadbolts, and specified Schlage B-series hardware for a keypad upgrade to bring all entry points to Grade 1 key control. We left a written record of every cylinder, every key, and every finish spec. That’s what a real estate hardware audit looks like.
No. A sticking deadbolt in spring and fall is almost always frame movement, not cylinder wear. Danville’s seasonal swings between wet winters and hot, dry summers cause wooden door frames on valley-built homes to swell and shrink. The deadbolt’s strike plate falls out of alignment with the throw, and the bolt binds. Rekeying the cylinder won’t change the geometry of the door. The fix is strike plate adjustment, a larger strike plate, or hinge tuning. We’ll tell you which one your door needs before we touch the lock. Call (331) 310-8471 and we’ll diagnose it over the phone, then confirm in person.
Yes, with the right preparation and hardware. Thick solid-core doors in Blackhawk estates often have non-standard door preps that don’t match consumer smart lock templates. We carry extended tailpieces, larger faceplates, and collar retrofits for doors over 1¾ inches thick. We drill only what the manufacturer’s template requires, and we document the door’s condition before and after. Most smart lock installs on custom Danville doors run $200-$450 depending on the prep work needed. If the door needs frame correction first, we quote that separately and in writing.
Rekeying changes the key; it doesn’t change the lock’s physical strength. A builder-grade deadbolt from the 1980s has a shorter bolt throw, weaker internal components, and no drill resistance. An ANSI Grade 1 deadbolt has a full 1-inch throw, hardened steel internal pins, and passes a much more demanding forced-entry test. For a Danville homeowner who just needs a new key after a roommate moves out, a rekey at $25-$45 makes sense. For a Blackhawk estate or any home where forced-entry resistance matters, replacement at $85-$180 is the better call. We’ll show you the difference in person and quote both options in writing. Call (331) 310-8471 for a firm quote.
