Fast, Reliable Lock Installation & Rekey Across Chicago
Lock installation and rekeying in Chicago runs $89-$275 for most residential jobs, with same-day scheduling available throughout the city. Our Lock Installation & Rekey team has worked Chicago’s neighborhoods for over 42 years, from the brick two-flats of Bridgeport to the greystone six-flats of Logan Square. We quote a flat price before the truck rolls, and every job carries our 90-Day Done Right Promise in writing.
Chicago’s housing stock is unlike anywhere else. Roughly 80,000 Chicago bungalows built between 1910 and 1940 still stand, alongside dense corridors of brick two-flats and three-flats in Pilsen, Bridgeport, and across the South and West Sides. That legacy hardware - Corbin, Yale, Russwin - requires a locksmith who knows when to rekey, when to retrofit, and when to replace. We’ve handled it all. Call (844) 321-2640 for a free estimate.
Why Strongbox Lock & Safe Co. of Illinois Is Chicago’s Preferred Lock Installation & Rekey Company
We’ve been in Chicago long enough to remember when Logan Square’s Milwaukee Avenue corridor was still predominantly Polish-owned two-flats, and we’ve rekeyed locks through every wave of neighborhood change since. Our technicians know the difference between a standard Kwikset installation in a Near North high-rise and a vintage mortise retrofit in a 1920s bungalow on the Far Northwest Side.
Chicago customers call us back because we show ID at the door, wear a uniform, and quote the real price on the phone. No $19 bait-and-switch. No vanishing after the invoice. The price we quote is the price you pay. Our 90-Day Done Right Promise means if something isn’t right, we come back. No paperwork to file, no argument to win.
A live person answers our phones 24 hours a day, including nights, weekends, and holidays. No voicemail trees. We understand that a lockout on a January night in Chicago, with the wind off Lake Michigan pushing temperatures below zero, is not a situation that can wait for business hours.
We also maintain a permanent 5% discount for seniors and veterans, and our $89 Seasonal Tune-Up catches alignment and wear issues before they strand you outside your own door.
Our Lock Installation & Rekey Services in Chicago
Smart Lock Installation
Smart lock installation in Chicago requires more than drilling a new hole. Many of our calls involve retrofitting Wi-Fi or Z-Wave deadbolts into century-old doors with non-standard bore sizes, especially in bungalows and greystones where the original mortise pocket doesn’t match modern hardware. We install Yale Assure, Schlage Encode, and Kwikset Halo systems, and we make sure your smart lock actually locks - not just connects. Chicago’s older door frames, prone to seasonal shifting, need proper strike-plate alignment or the motorized bolt will grind itself flat by spring.

Keyless Entry & Keypad Lock Installation
Keypad locks solve a specific Chicago problem: the tenant or family member who loses keys during a move, or the landlord managing turnover across multiple units. For Pilsen three-flats and Bridgeport two-flats, we install Schlage and Baldwin keypad deadbolts that eliminate rekeying costs between tenants while maintaining RLTO compliance. A single master code with temporary user codes beats chasing down copies of a physical key. We quote flat pricing for keypad installation - typically $180-$320 depending on door prep - and we program the lock before we leave.

Biometric Lock Installation
Biometric locks - fingerprint readers - are increasingly requested for owner-occupied units in Chicago’s denser neighborhoods, where multiple generations or roommates share a single entry. We install fingerprint-enabled deadbolts from select manufacturers, though we counsel Chicago customers honestly: extreme cold can slow sensor response, and lake-driven moisture requires sealed units rated for the temperature swings we see here. For most Chicago residential applications, a quality keypad or smart lock proves more reliable year-round. We’ll tell you if biometric makes sense for your specific building and exposure.

Electronic Lock & Key Duplication
Electronic lock service covers everything from hotel-style card readers in Near South Side condo conversions to magnetic strike releases on vintage intercom systems in Douglas courtyard buildings. We also cut keys on-site for Chicago customers - standard Kwikset and Schlage, high-security Medeco and Mul-T-Lock, and the occasional legacy Yale or Russwin blank that’s getting harder to source. Our key duplication runs $4-$18 per key depending on the keyway, and we carry blanks for most Chicago hardware in our service vans.

Trusted Brands We Service in Chicago
We stock and install Kwikset, Medeco, Yale, and Baldwin hardware, with parts in our vans for same-day completion on most Chicago calls. That matters when you’re facing a May 1 lease turnover and need matching keyways across four units in a Logan Square three-flat. We don’t show up with whatever’s on the truck and hope it fits. We ask about your existing hardware when you call, confirm the brand and keyway, and bring the right components. For Chicago’s legacy Corbin and Russwin hardware, we maintain relationships with specialty suppliers for the blanks and cylinders that big-box stores stopped carrying decades ago.
Common Lock Installation & Rekey Problems We See in Chicago Homes
- Frozen pin-tumbler cylinders from lake-moisture intrusion. Chicago’s winter wind chills below -20°F drive moisture into exterior locks, where it freezes and expands inside the cylinder. We replace damaged cylinders with weather-sealed units rated for the temperature range we actually see here.
- Strike-plate misalignment from seasonal brick expansion and contraction. The limestone and brick door frames on older two-flats and greystones shift measurably between winter cold and summer heat above 95°F. Deadbolts that worked in September refuse to engage by January. We adjust or relocate strike plates to account for this seasonal movement, not just file the edge and hope.
- Legacy mid-century hardware with obsolete parts. Original Yale, Russwin, and Corbin hardware in Chicago bungalows often cannot be rekeyed because replacement pin kits are no longer manufactured. We diagnose this on the phone when possible, so you know whether you’re looking at a rekey or a full retrofit before we arrive.
- RLTO-compliance rekeying on compressed timelines. Chicago’s Residential Landlord and Tenant Ordinance mandates new or rekeyed locks for every incoming tenant, and the May 1 and October 1 lease-turnover dates create predictable volume surges. We pre-stage rekey kits and schedule blocks for landlords with multiple units, because waiting until April 30th to call means joining the queue.

FAQs - Lock Installation & Rekey in Chicago
Yes. Chicago’s Residential Landlord and Tenant Ordinance (RLTO) legally requires landlords to provide new locks or rekeyed locks to every incoming tenant. This applies to all residential rental units in Chicago, not just large buildings, and failure to comply exposes landlords to penalties and tenant claims. We handle RLTO-compliance rekeying throughout the city, and we can coordinate multi-unit jobs to minimize downtime between lease dates. Call (844) 321-2640 to schedule - estimates are free, and we offer $50 off any repair over $250.
Sometimes. We rekeyed a vintage Corbin mortise lock in a Logan Square greystone on May 1, swapping out the original pin tumbler for a Schlage C keyway to meet RLTO compliance while preserving the historic brass faceplate. Whether rekeying is possible depends on whether replacement pins and springs are still manufactured for that specific Corbin or Yale model. Many mid-century Chicago locks use obsolete keyways. We diagnose this by phone when you can send photos of the lock face and keyway, so you know upfront whether rekeying or full retrofit is your path. Call (844) 321-2640 - we’ll give you a straight answer.
Seasonal expansion and contraction of the brick or limestone door frame throws the strike plate out of alignment. Chicago’s temperature swing from summer highs above 95°F to winter wind chills below -20°F causes measurable frame movement in older masonry construction. The deadbolt that slid home easily in September now grinds against the strike plate edge in January. We adjust or relocate the strike plate to account for this seasonal shift, and we sometimes recommend a slightly longer bolt throw or reinforced box strike for buildings with chronic movement. Call (844) 321-2640 for a flat-quote adjustment - our $89 Seasonal Tune-Up catches this before it strands you outside.
We rekey and install Kwikset, Schlage, Yale, Baldwin, Medeco, Mul-T-Lock, Abloy, and Sargent hardware. For Chicago’s legacy hardware - Corbin, Russwin, and older Yale mortise locks - we stock specialty blanks and cylinders that most suppliers discontinued. We carry pre-staged rekey kits for the May 1 and October 1 RLTO surge, so matching keyways across multi-unit buildings happens in a single visit. Call (844) 321-2640 with your lock brand and we’ll confirm parts availability before we roll.
Count your locks, identify the brands and keyways currently in use, and confirm your target move-in date at least two weeks ahead for May 1 or October 1 turnover. We need to know whether all units share a master key system, whether exterior security doors require separate hardware, and whether any locks have been replaced piecemeal over the years with mismatched brands. For a Pilsen three-flat, we typically schedule two to three hours for a full RLTO-compliance rekey, and we bring enough pre-staged Kwikset or Schlage cylinders to complete every door in one trip. Call (844) 321-2640 - we’ll walk through your building layout and quote a flat price for the complete job.
