Lock Installation & Rekey in Belmont Cragin: What It Costs and How It Works
Lock installation and rekeying in Belmont Cragin typically runs $75-$180 per cylinder for rekey work and $220-$480 for a full lock installation, including hardware and labor. A standard tenant-turnover rekey of a two-flat’s exterior doors is usually quoted in writing before we dispatch and completed the same day. If you’re off Fullerton, Diversey, or Belmont and need the job done right and documented, call (331) 310-8471 for a firm price before anyone heads your way.
Belmont Cragin’s housing stock was largely built between the 1920s and 1950s, and that shapes nearly every lock job here. We work on brick bungalows, courtyard two-flats, and three-flats with original mortise locksets, warped wood frames, and hardware that big-box stores no longer stock. This is not a neighborhood where you want a technician who only knows modern cylindrical locks. You want someone who can look at a 1940s Corbin mortise lock and tell you honestly whether it can be rekeyed or needs to be replaced.
Why Belmont Cragin Landlords and Homeowners Call Novak Lock & Security
We’ve lost count of how many calls start the same way: a landlord on a side street off Pulaski skipped the $75 rekey between tenants, and now a former occupant still has a working key. By the time they call us, it’s an emergency, and the cost is higher than the rekey would have been. Our Lock Installation & Rekey team handles this specific cycle constantly in Belmont Cragin because the neighborhood’s owner-occupied two-flat and three-flat buildings average a tenant turnover every 18 to 24 months.
Daniel Novak founded this company in 2002 on a rule that still applies on every job: the price you’re quoted on the phone is the price on the invoice. Haven Standard Clause 1. No technician is permitted to change it at your door. That’s the foundation of the business, and it’s written into every dispatch. Our technicians are background-checked, uniformed, and they leave you a documented photo record of every visit, including the condition of the hardware before and after we touch it.
Response time to Belmont Cragin is typically 45 to 60 minutes, depending on traffic on Grand or Fullerton. If it’s a lockout from a seized January cylinder after a polar vortex event, we treat it as the emergency it is. Calls are answered by a live person, 24/7. No voicemail queue between you and a real answer at 2 a.m.
Our Lock Installation & Rekey Services in Belmont Cragin

Smart Lock Installation
Smart lock installation in Belmont Cragin runs $280-$520 including the hardware, depending on the model and whether your door needs strike plate realignment. We install keypad, keyless, and app-controlled deadbolts on bungalows and two-flats throughout the neighborhood. One warning we give every customer on the older side streets: if the wood frame has shifted from decades of freeze-thaw cycles, the smart lock’s bolt needs to seat cleanly or it will jam the first winter. We realign the strike plate as part of the install, not as an add-on.

Keyless Entry
Keyless entry in Belmont Cragin is popular with owner-landlords who want to stop cutting new keys for every tenant. A keypad deadbolt install typically runs $260-$450. We code a new tenant code on move-in and delete it on move-out, which solves most of the RLTO rekey obligation while keeping a mechanical key override for emergencies. The keyless entry hardware we install isn’t the entry-grade stuff that fails in two years; we stock Schlage and Yale electronic deadbolts rated for exterior use in Chicago winters.

Keypad Lock
Keypad lock installation in Belmont Cragin typically runs $220-$380 for a quality deadbolt-grade unit. We see these used heavily on rental units along the Fullerton corridor, where landlords rotate access codes instead of physical keys. One thing we tell every customer: a keypad lock on a door with a misaligned frame will chew through batteries and eventually strip the internal gear. If your door sticks, we fix the door first.

Biometric Lock
Biometric lock installation in Belmont Cragin is a niche service, and we’re honest about it. A fingerprint deadbolt runs $350-$650 depending on the brand and cylinder grade, and we generally recommend them for the interior door between a shared entryway and a private unit, not for the exterior door facing January sleet. For high-security residential applications, we also install and service Mul-T-Lock and Medeco cylinders, which are pick-resistant and bump-resistant by design, and we quote every one in writing before we order parts.
We also handle key duplication in Belmont Cragin, including restricted high-security keyways that chain hardware stores can’t cut. If you need keys for a Medeco or Mul-T-Lock cylinder, bring the card. We cut and verify on the spot at our service van.

Trusted Brands We Service in Belmont Cragin
We’re factory-authorized on Medeco, Mul-T-Lock, Schlage, Yale, and Baldwin, and we carry the parts that matter for Belmont Cragin specifically. That includes vintage-compatible Corbin and Russwin interchangeable cores, because so many two-flats off Menard and Lawler still have their original 1940s and 1950s mortise locksets. When we install new hardware, we’re not limited to one brand and we don’t push a brand because we get a margin on it. We quote what fits your door and your threat model, in writing.
Common Lock Installation & Rekey Problems We See in Belmont Cragin Homes

- Original mortise locks with worn cylinders. The pin and tumbler cylinder inside a 1950s Corbin mortise lock wears down after 70 years. We can often rekey the existing cylinder with new pins and keys, which is cheaper than replacing the whole lockset. If the keyway itself is obsolete, the honest call is replacement, and we’ll show you the cylinder before we do it.
- Doors that shift with the seasons. Belmont Cragin’s brick two-flats sit on foundations that move. By February, the deadbolt on a 1930s bungalow door may not throw at all. Any new lock installed on that door needs the strike plate and hinge alignment corrected first, or it will fail within a year.
- Former tenants with working keys. The classic Belmont Cragin emergency. A landlord skips rekeying after a tenancy ends, then a past occupant enters the building. We rekey the lock and cut new keys on site, and we explain what Chicago’s RLTO requires before the next turnover.
- Big-box hardware that doesn’t fit. A homeowner buys a $40 lock from a hardware store, discovers it won’t fit a 1930s mortise prep, and now has a hole in the door and no lock. We carry the specialty stock to either retrofit the door properly or install a lockset that matches the existing prep.

FAQs - Lock Installation & Rekey in Belmont Cragin

Yes, in most cases we can rekey the original mortise lock by replacing the pins inside the existing cylinder and cutting new keys, which runs $75-$180 per cylinder. The limit is the keyway: if the cylinder is so worn or obsolete that a key blank no longer exists, replacement is the honest call, and we’ll show you the cylinder while explaining it. Call (331) 310-8471 and describe your lock; we’ll tell you over the phone which path is likely before we even schedule.
Your legal obligation under Chicago’s Residential Landlord and Tenant Ordinance attaches at every tenancy change, so you should rekey between tenants each time, regardless of how recently the lock was rekeyed. The RLTO effectively treats a landlord’s failure to rekey as a security breach risk, and neighbor-to-neighbor turnover in Belmont Cragin’s two-flats makes this a near-constant event. We handle multi-unit rekey schedules and keep a key control record for every unit we service.
It will fit if the door is properly prepped and the frame is corrected first; smart lock installs on Belmont Cragin bungalows run $280-$520 including that prep. We routinely realign strike plates and adjust hinges on 1940s doors so the deadbolt throws cleanly in both July and February. If the door itself is too warped to correct, we’ll tell you before quoting a smart lock, because bolting electronics to a door that jams is a waste of your money.
Rekeying is enough in almost every case; the lock cylinder gets new internal pins so the old key no longer turns the plug, and we cut new keys for you at the same time. You don’t need to replace the entire lockset unless the existing hardware is damaged or the keyway is obsolete. Call (331) 310-8471 and we’ll rekey the cylinder before the end of the day, usually within an hour of dispatch.
We do. Our Belmont Cragin service vans carry vintage-compatible Corbin and Russwin interchangeable cores, cylinder springs, and pin kits, because the neighborhood’s housing stock was built around these locksets and most locksmiths don’t stock them anymore. On a two-flat off Fullerton near Menard, we rekeyed a 1950s Corbin mortise lock a landlord thought he’d have to replace entirely, cutting new keys on the spot and saving him a full hardware swap.
