Near North Side is not like other Chicago neighborhoods. It forces a locksmith to work across two completely different hardware worlds in the same afternoon: 1920s Sargent mortise locks in a limestone courtyard building on Astor Street, then a ButterflyMX smart panel in a River North high-rise. We’ve been doing exactly that since 2002, and we stock parts for both.
Why Novak Lock & Security Is Near North Side’s Preferred Lock Installation & Rekey Company
We’re independently owned and operated, led by Daniel Novak, and our technicians are background-checked and uniformed on every visit. The difference our Near North Side customers notice first is that we answer the phone. Not a voicemail queue, not a callback window - a live person, 24/7, who can quote a firm price. That rule has been in place since 2002 under Haven Standard Clause 1: the price on the phone is the price on the invoice.
Near North Side building managers and homeowners call us because we can service what’s actually in their buildings. Pre-war courtyard apartments along Dearborn and State Streets still run original Corbin and Sargent mortise locks. Modern Streeterville towers run electronic access systems tied to concierge desks and elevator controls. A locksmith who only does one or the other will fail half the buildings in this neighborhood. We handle both, and we document every job with a photo record before we leave.
Every lock installation or rekey in Near North Side is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right. Every job also includes a written scope and a written warranty, not a verbal handshake. That’s Lock Installation & Rekey done to The Haven Standard.
Our Lock Installation & Rekey Services in Near North Side

Smart Lock Installation
Smart lock installation in Near North Side typically runs $180-$350 per lock, including programming and a written setup record. We install and program Schlage Encode, Kwikset Halo, Yale Assure, and August locks in Gold Coast greystones, Old Town courtyard units, and River North condos. In older buildings with shifting door frames, we align the strike and bolt throw before mounting so the smart lock doesn’t bind in January when the limestone contracts.

Keyless Entry & Keypad Lock
Keypad and keyless entry installation in Near North Side runs $160-$320 per door, quoted in writing before we start. These systems make sense for multi-tenant courtyard buildings where residents change frequently - property managers on Astor and Dearborn Streets use keypad locks to avoid rekeying every time a tenant moves out. We can also program keypads to work alongside existing mortise locks without removing the vintage hardware.

Biometric Lock
Biometric lock installation in Near North Side runs $250-$450 per unit. These are popular with River North condo owners who want fingerprint or Bluetooth access without carrying keys. But in pre-war buildings with non-standard door prep, a biometric lock bolted onto an unaligned strike will fail within weeks. We address the frame condition first, then install and register fingerprints, and leave you with a printed setup record.

Rekey
Rekeying in Near North Side runs $95-$185 per cylinder depending on the lock type. Standard Kwikset or Schlage cylinders are at the lower end; original Sargent or Corbin mortise cylinders in Gold Coast greystones sit at the higher end because they require specialty pinning kits and sometimes a salvaged tailpiece or case spring. We stock vintage Corbin and Sargent parts specifically because this neighborhood still needs them.

Trusted Brands We Service in Near North Side
We’re factory-authorized on Baldwin, Mul-T-Lock, Sargent, and Abloy, and we service the full range from entry-grade Kwikset and Schlage up to high-security cylinders that can’t be picked or bumped by standard tools. For Near North Side customers, we also maintain a working stock of salvaged Corbin and Sargent mortise parts - the tailpieces, case springs, and trim screws that haven’t been manufactured in decades but are still holding up entryways throughout the Gold Coast and Old Town. If you need a part we don’t stock, we can typically fabricate a replacement in our shop rather than telling you to replace the whole vestibule.
Common Lock Installation & Rekey Problems We See in Near North Side Homes

- Freeze-thaw frame shift in Gold Coast greystones. Brick and limestone door frames along Astor, Dearborn, and State Streets move with Chicago’s temperature swings - often 40°F in a single late-winter day. New deadbolts bind or fail to latch, and the fix is an alignment shim or strike adjustment, not a new lock. We shim and adjust on every install in pre-war masonry buildings.
- Non-standard vestibule tailpieces in courtyard buildings. The ornate entry hardware in pre-war courtyard buildings uses tailpiece lengths and shapes that haven’t been manufactured since the 1940s. An off-the-shelf deadbolt install leaves the inside trim loose and the cylinder misaligned. We either match the tailpiece from salvage stock or machine one to spec.
- Proprietary electronic locks in Streeterville and River North high-rises. Many condo towers run ButterflyMX or Latch access control tied to the building’s elevator and concierge systems. Forcing a standard rekey on these locks can void the access-control warranty and knock out the front desk’s override. We coordinate with building management and work within the existing system.
- Salt-air corrosion on lakefront hardware. Lake Michigan’s proximity accelerates corrosion on exposed deadbolts and padlocks, especially in Streeterville and on near-lakefront properties. We see pitted cylinders and seized tumblers that a standard rekey won’t fix - those need cylinder replacement with corrosion-resistant hardware, which we quote as a separate line item.
Pricing for Lock Installation & Rekey in Near North Side, IL
Here are the numbers we quote over the phone, before anyone is dispatched. A standard rekey in Near North Side runs $95-$185 per cylinder. New deadbolt installation runs $150-$260 per door.

We’ll tell you exactly what we’re quoting and why. Estimates are free. Call (331) 310-8471 and ask for a written quote - you’ll have the number in minutes, not after an on-site “assessment.”

FAQs - Lock Installation & Rekey in Near North Side

Yes. We rekey original Corbin and Sargent mortise locks throughout the Gold Coast and Old Town without replacing the vintage hardware. We stock salvaged mortise parts - tailpieces, case springs, trim screws - and we rekey the existing pin and tumbler cylinders so residents can move to a bump-resistant key control system while keeping the original limestone entry frame and vestibule hardware intact. Call (331) 310-8471 for a firm quote on your specific building.
Yes, in most cases residents can have traditional deadbolts on their unit door alongside the building’s ButterflyMX or Latch system. We coordinate with building management, install a deadbolt that doesn’t interfere with the access-control hardware or elevator restrictions, and document the install so the building’s warranty stays intact. We recently installed and programmed a ButterflyMX smart access panel for a River North condo conversion while adding keypad and deadbolt access per unit. Call (331) 310-8471 and we’ll review what your building allows.
Chicago’s freeze-thaw cycle - often swinging 40°F in a single day in late winter - causes the brick and limestone door frames in Streeterville and throughout the Near North Side to shift and rack. That movement makes newly installed deadbolts bind or fail to latch, which is the top callback we prevent by shimming and adjusting the strike before installing the lock. We build frame alignment into every masonry-building install. Call (331) 310-8471 for a quote that includes the alignment work.
Rekeying is cheaper in nearly every case - $95-$185 per cylinder versus $150-$420 per door for replacement. If the existing hardware is sound, rekeying restores security without replacing the lock. If the hardware is worn, corroded, or non-standard, replacement may be the better call, and we’ll tell you which one we’d actually do if it were our building. Call (331) 310-8471 and describe the door - we’ll give you a firm price for both options.
Non-destructive entry means opening a locked door without drilling, prying, or damaging the door or frame. It matters in pre-war courtyard vestibules because the ornate entry hardware and limestone frames are original - a forced entry means weeks of custom repair and an HOA that never calls you again. We use non-destructive methods first, and when drilling is genuinely necessary, we tell you before we do it and quote the door repair separately. Call (331) 310-8471 anytime - we’re available 24/7 for lockouts across Lock Installation & Rekey in Near North Side.
