Fast, Reliable Lock Installation & Rekey Across Hamilton
Lock installation and rekeying in Hamilton, OH typically runs $65-$185 per cylinder, quoted in writing before we dispatch. That price does not change at the door. If you live in the Dayton Lane Historic District, Lindenwald, or the near north side, you already know that Hamilton’s older homes don’t take modern hardware without some persuasion. We work on those doors every week. Call (331) 310-8471 and a live person answers, day or night.
Hamilton’s housing stock is not like Fairfield’s. Most of the city’s core was built between 1900 and 1950, when millworkers at Champion and Armco suppliers needed dense, affordable homes near the Great Miami River. Those houses came with cast-iron mortise locks, narrow backsets, and solid wood doors that have now been swelling and contracting through a century of Ohio freeze-thaw cycles. Standard Kwikset deadbolts do not simply drop into those frames. That’s the work we do here, and it’s why a Novak technician arrives with filler plates, custom backplate material, and the tools to re-bore a door without ruining it.
Why Novak Lock & Security Is Hamilton’s Preferred Lock Installation & Rekey Company
Novak Lock & Security has been installing locks and rekeying cylinders since 2002, with over 60,000 locks, keys, and systems serviced since then. Every job starts with a written price and ends with a documented photo record. That’s not a marketing line. It’s Haven Standard Clause 1: the price on the phone is the price on the invoice. Daniel Novak built the company on that rule because the locksmith trade has a bait-pricing problem, and the only way to separate from it is to put the number in writing before a tech gets in the van.
Our technicians are background-checked and uniformed. They arrive in Hamilton with the specific hardware this city’s houses demand: extended lip strike plates for frames that have drifted, restricted keyway cylinders for landlords who need key control, and retrofit kits sized for narrow backsets. When we finish a job on a 1920s mortise lock in the Dayton Lane district, we leave a photo record showing what was found, what was done, and what the finished hardware looks like. You can show it to a tenant, a buyer, or your insurance company.
Hamilton customers call us for the same reason they read the three-star reviews before hiring anyone: they want to see the evidence. We provide it. Every visit includes a written scope, a firm price, and a documented record. The 365-Day Done Right Promise backs it: if the work isn’t right, we make it right.
Our Lock Installation & Rekey Services in Hamilton
Smart Lock Installation
Hamilton homes with original mortise locks can still take a smart lock, but the installation is rarely off the shelf. A Yale or Schlage smart deadbolt needs a standard 2⅛-inch cross-bore and a backset of 2⅜ or 2¾ inches. Many doors in Hamilton’s older stock have a 1¾-inch or even narrower prep, or the existing mortise pocket interferes with the new tailpiece. We retrofit the door first, then mount the lock. Smart lock installation on a Hamilton home typically runs $185-$385 including the door prep work. The written quote includes everything.
Keyless Entry
Keyless entry systems make sense for Hamilton’s rental corridors, where turnover rekeys happen constantly. A keypad deadbolt with a new code for each tenant eliminates the copy-key problem. For a homeowner on the near north side, keyless entry means no more hiding a spare under a rock by the back steps. Installation on a modern pre-drilled door runs $150-$280. On an older door needing retrofit work, expect $220-$400. The price is in writing before we start.
Keypad Lock
A keypad lock is the most requested keyless upgrade in Hamilton right now. Landlords in Lindenwald use them to issue temporary codes to contractors. Homeowners use them for dog walkers or kids coming home from school. We install Schlage and Baldwin keypad deadbolts, and we stock the extended strike plates and filler plates these older Hamilton doors need so we’re not making a second trip. Keypad lock installation runs $170-$320 depending on the door condition and whether we need to re-bore the cross-bore opening.
Biometric Lock
Biometric locks read a fingerprint instead of a key. They’re a strong option for Hamilton homeowners who want to eliminate key copies entirely, especially if a previous owner or tenant may still have keys floating around. Installation is more involved than a standard keypad, and on older doors we often need to rebuild the door edge and install a reinforced strike. Biometric lock installation in Hamilton typically runs $280-$520. We quote the full price on the phone, including any door prep, before anyone is dispatched.
Key Duplication
Not every key can be copied at a hardware store in Hamilton. High-security cylinders from Medeco, Mul-T-Lock, and Abloy use restricted keyways that require a factory-issued card to duplicate. We hold those cards for our customers and cut restricted keys in-house. For standard Schlage and Kwikset keys, we duplicate them while you wait. Key duplication runs $3-$9 per key for standard cuts, and $15-$45 per key for restricted or high-security blanks. If a tenant has been copying keys without permission, the answer is a restricted keyway, not another standard copy.

Trusted Brands We Service in Hamilton
We install and service the full range on Hamilton doors: entry-grade Schlage and Kwikset, mid-grade Baldwin, and high-security Mul-T-Lock and Sargent. That matters because the right answer for a 1920s Dayton Lane mortise lock is not the same as the right answer for a 2018 build near the river. We stock filler plates, extended strikes, and retrofit kits sized for Hamilton’s older frames, so turnaround is same-day on most jobs. All work on these brands is factory-authorized, with the warranty in writing.
Common Lock Installation & Rekey Problems We See in Hamilton Homes
- Original mortise pockets too shallow for modern deadbolts. A 1930s rental in Lindenwald will often have a mortise pocket cut for a narrow cast-iron lock body, not a modern Grade 1 deadbolt. The fix is a custom backplate or full re-boring. We do this on site, not in a shop, and the quote accounts for it before we start.
- Freeze-thaw drift has shifted the strike plate. Hamilton’s winter-to-summer cycle makes wooden door frames move. The deadbolt throws fine in July and won’t throw in January because the frame has contracted and the strike is no longer aligned. This is not a rekey issue; it’s a strike plate and frame adjustment. We fix it with extended lip strikes and re-seat the plate so the bolt travels cleanly every season.
- Tenant key copies have destroyed key control. A landlord near Dayton Lane will tell us a tenant moved out, and now there are six copies of the front door key floating around the building. We rekey to a restricted Mul-T-Lock or Medeco keyway. New keys can only be cut by us, with the owner’s authorization. That ends the copy problem permanently.
- Skeleton-key or narrow-ward cylinders in original mortise locks. Many Hamilton homes still have the original keyway from the 1920s or 1930s. You cannot rekey that cylinder with modern pins because it isn’t a pin-and-tumbler design. We swap the cylinder for a modern mortise cylinder that fits the same lock body, keeping the original hardware on the door. It runs $85-$145 per cylinder, and we re-mill the keyway to match a restricted blank if you want key control.
Pricing for Lock Installation & Rekey in Hamilton, OH
A standard rekey in Hamilton runs $65-$185 per cylinder, and most homes have two to four cylinders to rekey. That gets each lock re-pinned to a new key, with the old keys rendered useless immediately. A new deadbolt installation on a modern pre-drilled door runs $150-$280. On a 1920s or 1930s door with a shallow mortise pocket, expect $220-$420 because the job involves custom filler plates or re-boring.
Smart lock and keypad installation lands between $170 and $385. A restricted-key rekey for landlord turnover runs $25-$45 per cylinder on top of the base rekey price, plus the cost of the restricted blanks. We give the full price on the phone. No call-out surcharge added when the tech arrives. No percentage added at the end. No “it’s worse than we thought” upcharge halfway through. The written price is the price. Bring us a competitor’s written estimate and we’ll review it at no charge.

FAQs - Lock Installation & Rekey in Hamilton
We can rekey most original mortise locks in Dayton Lane homes, as long as the lock body is mechanically sound. The original cylinder may need to be swapped for a modern mortise cylinder that fits the same lock body, which lets us keep the antique hardware on the door and still put a new key in your hand. Rekeying a mortise cylinder runs $85-$145 per cylinder. We’ll inspect the lock body first and give you a written price before any work starts. Call (331) 310-8471 for an exact quote.
We rekey the cylinder to a restricted keyway, which means new keys can only be cut by us with your written authorization. That ends the copy problem permanently because no hardware store in Hamilton can duplicate a restricted blank. The rekey itself runs the standard $65-$185 per cylinder, plus $25-$45 per cylinder for the restricted keyway conversion. We also document every lock we rekeyed with a photo record so you have a written record for the turnover file. Call (331) 310-8471 and we’ll walk through the building with you.
That’s almost always a strike plate and frame alignment problem, not a rekey issue. Hamilton’s freeze-thaw cycle makes the wooden frames on older near north side homes contract in winter, pulling the strike plate out of alignment with the bolt. We re-seat the strike, install an extended lip plate if needed, and the deadbolt throws cleanly. The repair runs $75-$145. We’ll also check the lock cylinder for moisture damage while we’re there, since the Great Miami River corridor keeps ambient humidity elevated. Call (331) 310-8471 for a free estimate.
Yes, but the door needs prep work first. A 1940s door with a 1¾-inch backset won’t take a modern smart deadbolt without re-boring the cross-bore opening and fabricating a filler plate for the old mortise pocket. We do that on site, and the written quote includes it. Smart lock installation on a narrow backset door in Hamilton typically runs $220-$420, depending on how much of the original mortise cut needs to be filled. Call (331) 310-8471 and we’ll tell you exactly what your door needs.
A rekey changes the internal pins inside the cylinder so the old key no longer works and a new key does. The lock hardware itself stays on the door. Rekeying is cheaper than replacing: $65-$185 per cylinder versus $150-$420 per new lock, and you keep the original hardware if it’s in good shape. We rekey on site, usually within an hour for a standard three-lock house. If the lock body is worn or the door frame has shifted, we’ll tell you that directly and give you a written price for the repair as a separate line item. Call (331) 310-8471 for a free estimate.
