Fast, Reliable Lock Installation & Rekey Across Naperville
Lock rekey in Naperville typically costs $25-$45 per cylinder, and a full deadbolt replacement with labor runs $120-$240 depending on the hardware grade you choose. Most jobs are completed the same day, and we quote the exact price on the phone before anyone is dispatched. That price is the price on the invoice. Novak Lock & Security has installed and serviced tens of thousands of locks across Naperville since 2002, and our dispatchers answer the phone live around the clock. Call (331) 310-8471 for a written estimate before you commit to anything.
Naperville’s housing stock presents a specific set of lock problems. The city’s explosive growth from the mid-1980s through the early 2000s blanketed the east and west sides with large planned subdivisions full of builder-grade Kwikset and Schlage entry sets. Those locks are now 20-40 years old and failing at roughly the same rate across entire streets. Homeowners in Naperville aren’t just locked out, they’re locked into aging hardware that was never meant to last this long. Our Lock Installation & Rekey team knows exactly what’s behind those doors because we’ve opened and rekeyed thousands of them.
Why Novak Lock & Security Is Naperville’s Preferred Lock Installation & Rekey Company
We’re independently owned and operated, led by Daniel Novak, and every technician who arrives at your Naperville home is background-checked and uniformed. What matters more than any badge is what we leave behind: a documented photo record of the lock condition before and after the job, a written scope of work, and a warranty in writing. That’s The Haven Standard, and it applies to every one of the 60,000+ locks and keys we’ve serviced since 2002.
Response time to Naperville neighborhoods like Hobson West, Ashbury, and White Eagle is usually under 45 minutes for emergency lockouts and same-day for scheduled rekeys and smart lock installs. We don’t route through a voicemail queue. A live person answers the phone 24/7, which matters when your deadbolt has seized at 11pm on a February night.
The 365-Day Done Right Promise covers every lock installation and rekey we perform in Naperville. If it’s not done right, we make it right. That’s not a marketing line. It’s a written term on the invoice.
Our Lock Installation & Rekey Services in Naperville
Smart Lock Installation
Naperville homeowners routinely ask us to pair smart locks with existing Z-Wave hubs or Apple HomeKit setups. We install Schlage Encode, Yale Assure, and other connected deadbolts on doors with standard 2-3/8″ backset prep, which covers nearly every colonial and four-square built in the 1985-2005 wave. A smart lock install in Naperville runs $150-$350 including hardware and programming, quoted in writing before we touch the door.
Keyless Entry and Keypad Lock Installation
Keypad deadbolts are the most common upgrade we install in Naperville’s HOA communities, because they let owners issue temporary codes to contractors, dog walkers, and cleaners without handing out keys that can be copied. Installation takes about 45 minutes and runs $130-$280 depending on the grade of the keypad. We always confirm the existing deadbolt’s backset and bore before quoting so there are no surprises.
Biometric and Electronic Lock Installation
For Naperville homeowners who want fingerprint or Bluetooth access, we install biometric deadbolts and electronic locks from Schlage and Yale. These units require a solid door with proper alignment, which is why we check the frame condition first. Freeze-thaw cycles in Naperville rack steel frames out of square, and a biometric lock won’t engage if the deadbolt throw isn’t lining up. We correct the alignment as part of the install. Biometric lock installation in Naperville runs $220-$400.
Key Duplication
We cut standard and high-security keys for Naperville customers, including restricted keyways from Medeco and Mul-T-Lock. Standard key duplication is $3-$8 per key. High-security keys require proof of ownership and run $15-$30 per key. For condo buildings near the Riverwalk with restricted master key systems, we coordinate with property management to ensure duplication stays within the key control policy.

Trusted Brands We Service in Naperville
We carry a working inventory of hardware from Schlage, Kwikset, Yale, Baldwin, Medeco, and Mul-T-Lock, so most Naperville jobs don’t require a second visit for parts. If you have a Baldwin mortise lockset in a downtown condo or a Medeco deadbolt on a commercial storefront near the Riverwalk, we service it in place and stock the common cylinders locally. No ordering delays for standard rekeys.
Common Lock Installation & Rekey Problems We See in Naperville Homes
- Freeze-thaw frame racking. Naperville’s temperature swings from -15°F to 90°F within a single year cause steel door frames in brick-veneer colonials to compress and shift. Deadbolts jam, tailpieces shear, and keys that worked in December won’t turn in March. The fix is frame realignment plus a deadbolt sized for the door weight.
- Aging builder-grade Kwikset deadbolts. Entire subdivisions in Naperville were built with identical Kwikset Signature Series hardware on identical pre-hung door units. After 20-40 years, the internal springs fatigue and the cylinders fail. We replace them with Schlage B60 deadbolts as a standard upgrade.
- Partial rekeys on multi-entry homes. Downtown Naperville condos and older homes often have three or four entry points with different keyways. A homeowner rekeys the front door and leaves the side door, garage door, and back door on old keys. We rekey every cylinder in one visit so every old key is dead.
- Copyable keys in multi-tenant buildings. Near the Riverwalk, older multi-tenant walk-ups often use the same key blank across units. One copied key becomes a building-wide access problem. We install restricted keyways or keypad entry systems that give property managers real key control.

FAQs - Lock Installation & Rekey in Naperville
Yes. If the deadbolt body is still functional, we can rekey the existing cylinder for $25-$45 without replacing the hardware. However, if you’re in a Naperville subdivision built between 1985 and 2005 and still have the original builder-grade Kwikset, we’ll usually recommend replacing the deadbolt with a Schlage B60 while we’re there, because the internal springs in those original units are near the end of their service life. Rekeying a failing lock just buys you a few months. Call (331) 310-8471 and we’ll tell you what condition your lock is in before quoting anything.
No, it’s a frame alignment issue caused by Naperville’s freeze-thaw cycles. When temperatures swing from -15°F to 90°F, the steel door frame in a brick-veneer colonial racks and compresses, which throws the deadbolt out of alignment with the strike plate. Rekeying won’t fix it. We realign the frame, lubricate the throw, and often replace the undersized tailpiece. If the deadbolt itself is worn, we install a new one. The repair typically runs $85-$150 for alignment plus hardware if needed.
Yes, in most cases. We install smart locks on condo doors in Naperville while preserving the building’s master key override, as long as property management approves the hardware. The smart lock needs to share the same cylinder keyway as the restricted system, which we can spec and order if it isn’t in our truck inventory. We coordinate directly with your condo board or property manager to make sure the installation doesn’t violate the building’s key control policy. Get approval first, then call (331) 310-8471 for a written quote.
Fast, because the homes are identical. In master-planned Naperville subdivisions like White Eagle, Ashbury, and Hobson West, every home on the street often has the same builder-installed Kwikset Signature Series deadbolt on the same pre-hung door unit. That means one rekey reveals the hardware profile for every neighbor’s front door. We can rekey a dozen homes on the same block in one afternoon, usually at $25-$45 per cylinder with a volume discount for cluster jobs. If you’re a block captain or HOA board member, call (331) 310-8471 and we’ll schedule a single visit for the whole street.
Yes, duplication is legal if you are the property owner or have written authorization from the property owner. “Do Not Duplicate” is a request stamped on the key, not a legal restriction in Illinois. A locksmith who refuses to copy a Do Not Duplicate key is exercising company policy, not state law. At Novak Lock & Security, we’ll duplicate a residential key stamped Do Not Duplicate when you can show proof of ownership, such as a mortgage statement or lease. For restricted high-security keys from Medeco or Mul-T-Lock, duplication requires a key control card from the locksmith or building that originated the system. Call (331) 310-8471 if you’re unsure whether your key falls into the restricted category.
