Fast, Reliable Access Control Systems Across Chicago
Access control system installation and repair in Chicago typically runs $1,200-$4,500 for a standard residential or small commercial setup, with most jobs surveyed and scheduled within 24-48 hours. We quote every project in writing before any work begins, and that written price is the price on the invoice. Haven Standard Clause 1.
Our Access Control Systems team serves Chicago from our local dispatch office, with crews working daily across the city from Pilsen to Rogers Park. We know the hardware that’s actually in these buildings, because we’ve been inside thousands of them. Call (331) 202-1318 for a written estimate.
Why Novak Lock & Security Chicago Is Chicago’s Preferred Access Control Systems Company
We’ve installed or serviced more than 60,000 locks, keys, and systems since 2002, every one with a written price before we started and a documented photo record when we left. In Chicago specifically, that work has concentrated in the pre-WWII housing stock that dominates neighborhoods like Logan Square, Bridgeport, and Woodlawn - two-flats, three-flats, and courtyard buildings with original mortise locksets that most technicians outside the Midwest rarely encounter.
Our reviews from Chicago customers consistently mention the same things: we name the price on the phone, we show up when we say we will, and we don’t drill locks that can be re-pinned. Our 365-Day Done Right Promise applies to every installation and rekey in the city.
Response time to Chicago neighborhoods is same-day or next-day for scheduled access-control surveys. Emergency lockout response runs 30-60 minutes depending on traffic and weather. Calls are answered by a live person, 24/7, with no voicemail queue or callback window.
What separates us from national dispatch services and suburban strip-mall locksmiths is simple: we stock Corbin, Yale, and Sargent mortise cylinders and adapters that fit Chicago’s original hardware. A technician who has to order parts can’t finish the job today. We usually can.
Our Access Control Systems Services in Chicago

Mortise Lock Rekey and Cylinder Replacement
In Chicago’s pre-WWII two-flats and courtyard buildings, access-control retrofits start with original in-wall mortise locksets - often 1¾-inch faceplates with obsolete Corbin, Yale, or Sargent cylinder threads - so a modern deadbolt or smart lock frequently cannot drop in without coring, patching, and re-drilling the stile. That’s a very different job than the surface-mounted, bored-cylinder work common in newer Sun Belt and suburban housing.
We rekey original mortise cylinders where the threads and keyways are still serviceable. When the cylinder is obsolete, we source matching replacements or machine adapters rather than destroying the historic faceplate. A typical mortise rekey in Chicago runs $45-$85 per cylinder; cylinder replacement with sourcing runs $120-$280 depending on rarity. Both are quoted in writing before we start.

Master Key System Design for Two-Flat and Courtyard Landlords
The Chicago Residential Landlord and Tenant Ordinance (RLTO) requires landlords to rekey between tenants. For the owner-occupied two-flats common in Pilsen, Avondale, and Bridgeport, we design two-level and three-level master key systems that let landlords rekey individual units without replacing the century-old common-entry lockset.
Our field vignette: Our techs were called to a Greystone two-flat in Logan Square where the front entry’s original mortise lock had been painted over for decades and the deadbolt no longer lined up after the door swelled in July. Rather than drilling, we used non-destructive entry to open the door, then re-pinned the existing mortise cylinder and shimmed and routed the strike so the bolt threw cleanly - keeping the historic faceplate intact and saving the owner a full hardware replacement. We also keyed the unit door and the building’s common entry into a two-level master key system so the landlord could rekey between RLTO turnovers without replacing the century-old lockset.
Master key system design in Chicago starts at $180 for a simple two-level setup and runs to $600+ for larger courtyard buildings with multiple common entries and unit tiers.

Keypad Entry and Smart Lock Retrofit on Original Doors
Chicago homeowners want modern access control. The problem: their 1920s doors. Solid wood, often 1¾ inches thick, with mortise pockets that won’t accept a standard bored-cylinder smart lock without major modification.
We retrofit keypad and smart lock hardware that works with existing mortise configurations, or we install complementary electronic strikes and readers where the original lock must remain for historic or structural reasons. On Greystone and Chicago common brick buildings, we also assess frame condition - decades of paint, patching, and settlement mean the strike location often needs re-routing before any electronic component will align.
Smart lock retrofit on original Chicago doors typically runs $350-$900 depending on whether we’re adapting existing hardware or installing new electronic strikes. Every scope is written and priced before we begin.

Non-Destructive Entry and Emergency Lockout Response
Chicago’s extreme seasonal swing causes lockouts that lubricant can’t fix. Solid-wood doors swell tight in July humidity and gap in January cold, throwing bolt alignment off twice a year in the same unit. Our emergency response covers the city with live-dispatched crews who carry mortise-specific picks, shims, and cylinder extraction tools.
We do not drill as a default. Our documented procedure requires non-destructive entry attempts on every lockout call, with drilling authorized only after the customer approves it in writing and understands the replacement cost. Emergency lockout service in Chicago runs $95-$175 during business hours and $145-$225 after hours, quoted firm on the phone.

Trusted Brands We Service in Chicago
We maintain local stock for Chicago’s mixed housing stock: Kwikset and Schlage bored-cylinder hardware for newer construction and retrofits, Medeco high-security cylinders for landlords who need pick-resistant and drill-resistant protection under the RLTO, and Baldwin mortise and deadbolt sets for historic-restoration work where finish and period correctness matter. We also source Yale and Sargent mortise cylinders and parts for original Chicago hardware that hasn’t been manufactured in decades. Factory-authorized work on all brands means your warranty stays intact, and our Chicago office carries common configurations so most jobs finish without waiting on shipping.
Common Access Control Systems Problems We See in Chicago Homes

- Obsolete mortise cylinders that won’t accept modern keyways. Pre-1945 two-flats and courtyard buildings across Logan Square, Bridgeport, and Woodlawn still run original Corbin, Yale, or Sargent cylinders with thread patterns no longer standard. A routine rekey stalls until the right adapter or replacement is sourced - something our Chicago stock usually covers.
- Freeze-seized cylinders after owner-applied graphite. Chicago’s polar vortex events push temperatures to -15°F or lower. Graphite lubricant gums up in aging mortise mechanisms, and the first deep freeze seizes the cylinder solid. Technicians who don’t recognize the cause often drill a perfectly serviceable lock instead of clearing and re-pinning it.
- Door swell throwing bolt alignment twice yearly. The same solid-wood door that gaps in January swells tight in July. We see this on Greystone two-flats and courtyard buildings throughout the city: the deadbolt that threw cleanly in winter won’t engage in summer, or vice versa. Shim and strike routing fixes it; cylinder replacement doesn’t.
- Painted-over mortise faceplates masking hardware condition. Decades of landlord paint jobs in Chicago’s rental stock hide corrosion, stripped screws, and cracked faceplates. We strip and assess before quoting replacement, because what’s underneath often changes the scope significantly.

FAQs - Access Control Systems in Chicago

Most original mortise cylinders in Chicago’s pre-1945 housing can be rekeyed if the threads are intact and the keyway is still manufactured or adaptable. We stock Corbin, Yale, and Sargent adapters for common Chicago configurations. When the cylinder is cracked, stripped, or uses a truly obsolete thread pattern, we source a replacement that fits the existing mortise body rather than replacing the entire lockset. Call (331) 202-1318 and we’ll identify your cylinder over the phone or during a free survey.
Yes. In Chicago’s climate, solid-wood doors swell and shrink seasonally, throwing bolt alignment off twice a year. We shim and re-route strikes, adjust mortise bodies, and sometimes plane strike edges - all without touching the door slab. Door replacement is rarely necessary for lock function. We quote the alignment work in writing after inspection; typical range is $85-$180.
The Chicago Residential Landlord and Tenant Ordinance requires landlords to change or rekey locks between tenants so the prior tenant’s keys no longer operate the unit. The ordinance does not mandate specific hardware grades or smart locks - only that the lock be changed or rekeyed. We document every RLTO rekey with a dated service record that satisfies the requirement. Master key systems let landlords rekey individual units without replacing common-entry hardware. Call (331) 202-1318 for a written scope on your building.
Non-destructive entry is our required first procedure on every lockout call. We carry mortise-specific picks, shims, and extraction tools for Chicago’s original hardware. Drilling is used only when non-destructive methods have been exhausted and the customer approves the replacement cost in writing. Our documented photo record shows the condition of the lock before and after entry. Emergency lockout service in Chicago runs $95-$225 depending on time and complexity.
Sometimes directly, sometimes with adaptation. A few smart lock models fit mortise configurations without major modification. More often, we install an electronic strike or reader that works with the existing mortise lock, preserving the original hardware while adding modern access control. The right approach depends on your door thickness, frame condition, and whether the building is landmarked. We survey and quote in writing before any work begins. Typical smart lock retrofit on original Chicago doors runs $350-$900.
