Why Pittsburg Homeowners Call Novak Lock & Security
We’ve worked on enough Pittsburg doors to know what fails here and why. The pre-WWII storefronts along Railroad Avenue, the 1950s tract homes in the west side, the newer builds up near San Marco Hills. Each has different hardware problems. We don’t send a rotating cast of subcontractors. The technician who shows up is background-checked and uniformed, works to The Haven Standard, and leaves you a documented photo record of the work before he pulls out of the driveway.
Daniel Novak founded this company in 2002 on a single rule that still governs every job: Haven Standard Clause 1, the price on the phone is the price on the invoice. That rule is the reason Pittsburg customers call us back when they move, when they add a rental unit, or when the Delta fog finally kills another exterior cylinder. We’ve installed or serviced 60,000+ locks, keys, and systems since 2002, every one with a written price before we started and a written record when we left. We answer our own phone, 24/7, no voicemail queue between you and a real answer.
For the lock installation and rekey work described on this page, our Lock Installation & Rekey process is the same everywhere, but the hardware we recommend changes by neighborhood. And in Pittsburg, the salt air is the deciding factor more often than not.
Our Lock Installation & Rekey Services in Pittsburg

Mortise Lock Installation & Rekey
Pittsburg’s older housing stock still has a lot of original mortise lock bodies from the 1940s through the 1960s. These are not drop-in replacements. A modern cylindrical deadbolt will not fill a mortise pocket without significant door modification. We rebuild or replace the mortise body, install a new cylinder, and rekey it to match any other locks you want on the same key. When the body itself is still mechanically sound, we can rekey the existing cylinder and save you the cost of full replacement.

Smart Lock Installation
Smart locks are the most-requested upgrade in Pittsburg right now, but they fail here for a specific reason. The channeled Delta winds push against entry doors all year, and even a slight frame shift makes a smart lock’s motorized bolt misread latch position and throw a “jammed” error. We don’t just screw on the new lock. We check alignment, realign the strike plate, and make sure the bolt throws cleanly before we leave. A smart lock installed on a warped hollow-core door without that alignment step is a callback waiting to happen.

Keyless Entry & Keypad Lock Installation
Keypad and keyless entry systems are practical for Pittsburg households with multiple family members, caregivers, or regular contractors. We install keypad deadbolts and lever sets on front, side, and garage entries throughout Pittsburg, including the neighborhoods off Buchanan Road and around Stoneman Park. Codes are set in front of you, tested in front of you, and documented in the photo record we leave behind.

Biometric Lock Installation
Biometric locks use fingerprint recognition instead of keys or codes. They’re an option for high-traffic entries and for homeowners who want a strict access record. The install has to account for the same alignment and humidity issues as any other hardware in Pittsburg. We’ll tell you honestly whether a biometric system is worth the cost on your specific door, and whether the existing frame can support it without a rebuild.

Key Duplication
Standard key duplication is straightforward. But if you need copies of a high-security key from a Medeco, Mul-T-Lock, or Abloy cylinder, that requires a key card and authorization, and we’re factory-authorized to cut them. For Pittsburg landlords and property managers, we can duplicate a full key set and key it to a master system, with a written keying schedule so you can track who holds which key.

Common Lock Problems We See in Pittsburg Homes

- Internal cylinder corrosion from Delta air. The keyway looks fine from the outside, turns smoothly with the key, but the pins and springs inside have been slowly rusted by the daily salt-and-moisture breeze off Suisun Bay. Rekeying without inspecting internals means the new pins bind within weeks. This is the single most common call we get in Pittsburg that almost never happens in Concord or Walnut Creek.
- Seized mortise lock bodies on original 1940s-1960s doors. The OEM mortise bodies on Pittsburg’s post-WWII tract homes are now 60-80 years old. The latch mechanism wears out, the deadbolt throw shortens, and a new cylinder won’t fix the underlying body. We rebuild or replace the mortise body, not just the cylinder.
- Warped hollow-core doors from channeled Delta wind. Years of constant westerly wind pressure against the original hollow-core entry door means the door slab no longer sits square in the frame. A brand-new deadbolt installed in that condition binds on the latch every time. The repair is realignment and a properly seated strike plate, not a more expensive lock.
- Mixed keying on post-WWII homes with additions. Pittsburg’s housing stock includes many homes that were expanded over the decades. Different doors carry different original hardware, and often a mix of Kwikset, Schlage, and mortise cylinders, each on a separate key. We consolidate them onto one key, or a master and tenant key for multi-unit buildings near Railroad Avenue.
Why Salt Air Changes Everything About Rekeying in Pittsburg
Pittsburg sits directly on Suisun Bay at the mouth of the Sacramento-San Joaquin Delta. Every afternoon, the Delta breeze pushes moisture and light salinity through the city. That salt air works its way into exterior lock cylinders. The pins and springs rust. The cylinder still turns, still accepts the key, but the internals are degrading. A technician who rekeys that cylinder without inspecting it has just given the customer a lock that will pin smoothly on the bench and seize again within weeks. We inspect first. If the pins and springs are corroded, we replace the cylinder or the entire lock. If the cylinder is clean, we rekey it and move on. That honesty is why we get repeat calls from homeowners all over Pittsburg, from the Marina district to the Central Avenue corridor.
We recently worked a 1950s tract home near Railroad Avenue where the original mortise lock on the front door had seized after decades of salt-air exposure. The Schlage cylinder looked functional, but the pins had corroded inside, so we replaced just the cylinder and rekeyed the new hardware to match the existing deadbolt. No full mortise body replacement needed, and the owner kept their original door intact. That’s the kind of call that makes the difference in Pittsburg. A less experienced shop would have either rekeyed a dying cylinder or sold a full door replacement that wasn’t necessary.
Pricing for Lock Installation & Rekey in Pittsburg, CA

Here are honest numbers for the Pittsburg market. A standard door knob or deadbolt rekey runs $25-$45 per cylinder. New deadbolt installation runs $110-$190, depending on hardware grade. Smart lock installation starts at $150-$240 including alignment and strike plate work. Mortise lock rebuild or replacement on older Pittsburg homes runs $180-$320. Key duplication runs $3-$8 for standard keys and $15-$45 for high-security keys with card authorization, if you have the card. The price we quote on the phone is the price on the invoice, full stop. Haven Standard Clause 1 has been in place since 2002, and none of our technicians is permitted to change the price at the door.
Does an Old Lock in Pittsburg Need Rekeying or Replacement?
Here’s the straight answer for most Pittsburg homes built before 1970. If the lock body itself is mechanically sound, the cylinder internals are clean, and the door sits square in the frame, a rekey is all you need. If the pins or springs inside the cylinder have corroded from the Delta air, replace the cylinder and rekey the new one to match the rest of the house. If the mortise body has worn latch components or a shortened deadbolt throw, rebuild or replace the body. If the hollow-core door has warped from the wind, the lock is not the problem; the frame alignment and strike plate are. A competent Pittsburg locksmith tells you which of these situations you have before quoting a price. That’s what we do. If you bring us another company’s written estimate, we’ll review it at no charge.

FAQs - Lock Installation & Rekey in Pittsburg

Not necessarily. A cylinder that turns smoothly but has been exposed to Pittsburg’s salt air for years may have internally corroded pins that will fail within weeks of a rekey. We inspect the internals before we rekey. If the pins and springs are clean, you pay for a rekey only. If they’re corroded, a cylinder replacement is the honest fix. Either way, you get the written price before we start. Call (331) 310-8471 and we’ll inspect it on site.
Yes, if the mortise body is mechanically sound. We rekey the existing cylinder in place and leave the original hardware intact. If the body has worn latch components, a rekeyed cylinder won’t fix that. We’ll tell you which situation you have before quoting anything. Estimates are free.
In Pittsburg, the channeled Delta winds have usually pushed the door out of square, and the smart lock’s bolt cannot seat cleanly in the strike plate. The fix is frame alignment and strike plate adjustment, not a new lock. We include that alignment work in every smart lock installation. Call (331) 310-8471 for a written quote.
Yes. We rekey multi-unit buildings in Pittsburg to a master key system, with each unit on its own tenant key and a single master that works across all units. You get a written keying schedule showing exactly which key opens which door. This is flat-per-lock pricing, quoted in writing before we begin.
Usually not. Tule fog accelerates the same internal corrosion the Delta breeze causes all year. If the keyway is intact and only the internals are corroded, we can replace the cylinder and rekey the new one to match your existing keys. You keep the original hardware body. A full replacement is only needed when the lock body itself has failed. We’ll show you the condition of the cylinder before we replace it.
