Fast, Reliable Lock Installation & Rekey Across Fairfield
Lock installation and rekeying in Fairfield typically runs $65-$145 for a standard rekey of an existing lock, and $150-$380 for full lock installation depending on the hardware grade and door prep required. Most jobs in Fairfield are completed same-day, often within 90 minutes of arrival. If you’re locked out, have a tricky mortise lock that needs a key, or want a smart lock installed on an older door, call Novak Lock & Security at (331) 310-8471. You’ll get a written price on the phone before we dispatch anyone, and that price is the price on the invoice. Haven Standard Clause 1: the price on the phone is the price on the invoice.
We work across every part of Fairfield: the historic center near Old Post Road, the condos by the Fairfield Metro station, the Stratfield and Tunxis Hill neighborhoods, and the shore-hugging streets around Southport. And we know the area’s peculiar locks. Pre-WWII mortise locksets that big-box replacement parts don’t fit. Coastal salt air that seizes a cylinder within a few winters. A condo board that needs key control because too many copies drifted out after tenant move-outs. This is not generic suburban lock work. It’s Fairfield lock work.
Why Novak Lock & Security Is Fairfield’s Preferred Lock Installation & Rekey Company
Fairfield homeowners call us because we name a real price, in writing, before we touch anything. That has been our practice since 2002, and it applies to every rekey, every smart lock install, every emergency lockout. Daniel Novak runs the company, and the business is independently owned and operated, working to The Haven Standard, the same documented quality framework applied across all ten Haven brands. Every visiting technician is background-checked and uniformed, and every job ends with a documented photo record left with the customer. Not a promise. A procedure.
The feedback we hear from Fairfield customers points to the same things. The dispatcher answered on the first ring. The technician arrived when we said he would. The invoice matched the quote. And the work held up through salt fog, hard freezes, and the daily wear of a family coming and going. We also offer a Free Second Opinion on Any Written Estimate. Bring us a competitor’s quote for lock installation or rekey work in Fairfield and we will review it at no charge. If it’s honest, we’ll tell you. If it’s not, we’ll tell you that too.
Our Lock Installation & Rekey Services in Fairfield

Our Lock Installation & Rekey team covers the full range, from a simple cylinder swap to full high-security upgrades on older Fairfield doors. Here are the services Fairfield homeowners ask about most.
Smart Lock Installation
Smart lock installation in Fairfield runs $180-$420 depending on the lock model, the door prep required, and whether you want Wi-Fi or Bluetooth connectivity. Older Fairfield doors often need a bit of retrofitting. A mortise lock with a narrow faceplate won’t accept a standard smart deadbolt without careful modification. We carry retrofit kits and we tell you honestly, before we start, whether your door can take the lock you want. We install Yale, Schlage Encode, and August models regularly, and we pair them with your existing keyway where that’s what you want. The 365-Day Done Right Promise applies to every smart lock we install: if the lock misbehaves and it’s our installation, we make it right.
A note specific to Fairfield: if you live within a quarter mile of the Sound, pick a smart lock rated for outdoor and high-humidity exposure. We’ve replaced too many cheap keypads that died after two winters of salt air.

Keyless Entry & Keypad Lock
Keypad lock installation in Fairfield runs $140-$330 for a quality deadbolt keypad, installed and programmed. We recommend Schlage or Yale keypad deadbolts for most Fairfield homes, and we program all user codes during the visit. For condos near the Fairfield Metro station, a keypad deadbolt with a built-in audit trail is often the single best retrofit for a door that has seen multiple tenants and too many copied keys. You get a record of who came and went, which is the kind of thing a condo board or landlord actually wants.

Biometric Lock Installation
Biometric lock installation in Fairfield is typically $250-$550 for a fingerprint or facial-recognition deadbolt, installed and enrolled with your family’s prints. These locks make sense for households near the Bridgeport border where door security is a genuine daily concern, not a checkbox. We supply and install models from Yale and eufy, and we always install a mechanical key override because fingerprint sensors fail in the cold, and Fairfield gets cold. Every biometric install includes a written price, a documented photo record, and the same 365-Day Done Right Promise.

Key Duplication
Key duplication in Fairfield is straightforward for standard keys and more involved for restricted keys. A standard Schlage or Kwikset copy costs $3-$8 per key. A Medeco or Mul-T-Lock restricted key costs $25-$65 per key and requires proof of ownership because the blanks are not sold to the public. If you own a condo or co-op near the Fairfield Metro station and your board uses a restricted key system, bring your owner card or management office authorization. We duplicate the key, record the serial, and give you a documented receipt. That’s the kind of key control that actually protects a multi-unit building.

Trusted Brands We Service in Fairfield
We service and install the full spectrum: entry-grade Kwikset and Schlage, mid-grade Baldwin, and high-security Mul-T-Lock, Medeco, Sargent, and Yale. Fairfield homes built before 1950 frequently carry original mortise locksets from brands that no longer manufacture replacement parts, which is where our parts inventory and sourcing network matters. We keep common Fairfield-specific hardware on hand: replacement cylinders for mortise bodies, longer latch bolts for thick Southport doors, and marine-grade strike plates for shoreline properties. If we need to source a part, we tell you the lead time and the price before ordering. No surprises.
Common Lock Installation & Rekey Problems We See in Fairfield Homes

- Seized mortise cylinders near the Sound. Salt air and coastal humidity corrode the brass and steel inside original mortise locksets within a few seasons. The key stops turning, then snaps off in the cylinder, and you’re locked out of your own front door. We replace the cylinder and clean the mortise body, and we fit marine-grade components where the exposure is worst.
- Original mortise locks in Southport and the historic center that won’t accept modern cylinders. The old lock body is too small for a standard replacement cylinder. Off-the-shelf deadbolts leave gaps or misalign with the old strike plate. We ream the door only when necessary, and we always match the new hardware to the old door’s thickness and the strike plate’s position. No door gets hacked up for the sake of a quick job.
- Duplicated keys floating around condo buildings near the Fairfield Metro station. A unit changes hands, a tenant moves out, and the key count keeps climbing. A basic rekey is a start, but without a restricted key system the old copies still work. We rekey to Medeco or Mul-T-Lock restricted keys so no one can walk into a hardware store and duplicate your building key. That’s the actual fix for a building-wide problem.
- Single-cylinder deadbolts with no bump or pick resistance on Stratfield and Tunxis Hill ranches. These homes were built when a standard Kwikset was considered fine. It is not fine anymore, especially with the sharp wealth-to-crime-rate boundary along the eastern border with Bridgeport. We install ANSI Grade 1 deadbolts and, where the budget allows, high-security cylinders that cannot be bumped or picked with standard tools.

We tell you the exact number before we come to your house. The price on the phone is the price on the invoice, and there is no call-out surcharge added on arrival. We’ve run it this way since 2002, and it’s the reason Fairfield homeowners read the three-star reviews of every other locksmith and then call us.

FAQs - Lock Installation & Rekey in Fairfield

Yes, in most cases we can rekey an original mortise lock without replacing the lockset itself. The work involves replacing the internal cylinder or re-pinning the existing cylinder to a new key, and it typically costs $95-$175 in Fairfield. If the mortise body itself is worn or corroded beyond reliable function, we’ll show you the condition and give you a written price for a compatible replacement before doing anything beyond the rekey. Call (331) 310-8471 and we’ll tell you exactly what your lock needs.
We send a tech out, typically within 30-45 minutes, and we open the vehicle without damaging the door or the weather seal. If the fob itself is the problem, we tell you whether it needs a new battery or a replacement, and we quote both before proceeding. Fairfield Metro commuters call us most on cold mornings when fobs die and the train doesn’t wait. The emergency lockout service quote in Fairfield runs $75-$140, and that price is set before dispatch.
A standard rekey changes the cylinder so the old key no longer turns it, and that stops every old standard key immediately. What it does not stop is unauthorized copies made before the rekey. If your condo building near the Fairfield Metro station has had keys floating around, the real fix is a restricted key system like Medeco or Mul-T-Lock, where blanks are not sold to the public and every copy is logged. Rekey plus restricted keys runs $95-$185 per cylinder in Fairfield, quoted in writing. Call (331) 310-8471 for an exact quote.
If you live in the eastern part of Fairfield near the Bridgeport line, yes, we recommend at least bump-resistant cylinders and ideally a high-security lock like Medeco or Mul-T-Lock. Fairfield’s eastern border creates a sharper wealth-to-crime-rate boundary than any other shoreline town in the county, and standard entry-grade locks are the first failure point. A high-security cylinder upgrade runs $95-$185 per cylinder, installed and keyed in writing. It is the single highest-impact security upgrade we perform in Fairfield.
It depends on the mortise body’s width and the door’s thickness, but in many Fairfield homes the answer is yes. We can either retrofit a compatible smart cylinder into the existing mortise body or install a smart deadbolt above the original lock while preserving the mortise for appearance. The installed smart lock price in Fairfield runs $180-$420. We always inspect the door first and tell you plainly if your particular door cannot take the lock you want. Call (331) 310-8471 and describe your door. We’ll give you a written range before you commit to anything.
