Why Strongbox Lock & Safe Co. of Illinois Is Markham’s Preferred Lock Installation & Rekey Company
We’ve been serving Markham and surrounding Cook County communities for over 42 years. That’s four decades of watching this city’s brick ranches and bungalows age - learning which deadbolts survive Cook County’s brutal January freezes and which ones seize up by Groundhog Day.
Our reputation here is built on showing up when we say we will and standing behind the work. The 90-Day Done Right Promise means if a lock we installed binds, slips, or fails, we come back. No paperwork to file, no argument, no charge. Just fixed.
Markham’s location just south of the Calumet Expressway puts us within easy reach - our technicians are typically at your door in under 45 minutes. We know the difference between a quiet residential street off 167th and the courthouse district near Dixie Highway, and we schedule accordingly.

Our Lock Installation & Rekey Services in Markham
Smart Lock Installation
Markham’s 1950s-1970s ranch homes weren’t built for Wi-Fi deadbolts, but that doesn’t mean they can’t get them. We regularly install smart locks on postwar doors with settled frames - the critical step is shimming and reinforcing the strike box so the motorized bolt doesn’t grind against misaligned wood every time it extends. For a recent job on 167th Street, we fitted a 1960s brick ranch with a keyless smart lock after upgrading the strike plate and frame prep. The homeowner now grants temporary codes to her rental tenant from her phone. Smart lock installation in Markham typically runs $220-$420 including hardware and frame adjustment.
Keyless Entry
Keyless entry systems are the practical upgrade for Markham’s high-turnover rental properties. When a tenant moves out at month-end, you reprogram the code instead of rekeying the cylinder - faster, cheaper over time, and no risk of copied keys floating around. We install keypad and touchscreen keyless entry units from Schlage, Yale, and Baldwin, selected for the temperature swings that hit unheated side entries on Markham’s older homes. A basic keyless entry install starts around $180; integrated smart-home models run higher. We quote flat before we drive.
Electronic Lock
Electronic locks bridge the gap between traditional deadbolts and full smart-home integration. For Markham homeowners who want push-button convenience without app dependency, we install standalone electronic deadbolts with illuminated keypads - especially useful for the senior homeowners who make up much of this community. These units handle Cook County’s freeze-thaw cycle better than basic mechanical locks because there’s no keyway to ice up. Electronic lock installation in Markham generally ranges $200-$350.
Biometric Lock
Biometric locks - fingerprint readers - are less common in Markham’s residential market but find their place in specific applications. We install them for home offices, gun rooms, and for a few law practices near the courthouse district where attorney-client confidentiality demands restricted access. The technology has improved; outdoor-rated biometric units now function reliably through Chicago winters. These are premium installations, typically $380-$580 in the Markham market.

Trusted Brands We Service in Markham
We stock and install Medeco, Yale, Baldwin, and Mul-T-Lock - brands that hold up to Markham’s conditions. Medeco’s restricted-keyway cylinders are our go-to for rental properties where unauthorized duplication is a concern. Yale’s electronic and smart-lock lines handle the temperature range we see on unheated entries. Baldwin’s solid brass hardware suits the homeowner who’s replacing a 50-year-old lockset and wants something that’ll last another 50. We carry common parts on our Markham-area trucks, so most jobs finish in one visit. If you’ve got a specific hardware requirement - a matching finish for a vintage door, a commercial-grade key-control system for a courthouse-district office - we’ll source it and quote you upfront.
Common Lock Installation & Rekey Problems We See in Markham Homes
- Settled frames jamming new deadbolts. Markham’s postwar ranch homes have shifted on their foundations for 60-plus years. Door frames that were square in 1962 are now parallelograms. We regularly arrive to find a homeowner’s new deadbolt grinding against a strike plate that’s an inch off-center. The fix isn’t forcing the lock - it’s adjusting the frame and relocating the strike box so the bolt slides true.
- Freeze-thaw cylinder seizures. Cook County’s winter temperature swings - 40 degrees in a day isn’t unusual - cause wooden door frames to swell and contract repeatedly. Unheated side entries on Markham’s older homes see the worst of it. We get the emergency calls in January: key turns halfway, then stops dead. Sometimes we can free the cylinder; sometimes the internal pins have corroded from years of moisture cycling, and replacement is the only reliable fix.
- Worn original locksets on converted rentals. Markham’s rental market moves fast, and many properties still carry the original owner-installed hardware. A Kwikset deadbolt from 1970 was built for a family who’d live there 20 years, not for six tenants in four years. The keyway wears oval. The latch bolt wobbles. Rekeying helps briefly, but eventually the hardware itself is done. We advise landlords when replacement is the smarter spend.
- Misaligned strike plates from repeated rekeying. Every time a different locksmith rekeys a lock without checking frame alignment, the bolt gets forced against off-center metal. The strike plate deforms. The bolt face mushrooms. Eventually nothing closes smoothly. We catch this on inspection and correct the geometry before installing fresh hardware.

FAQs - Lock Installation & Rekey in Markham
Yes - we do it regularly. The key is proper frame prep: shimming the strike box, enlarging or relocating the mortise, and ensuring the motorized bolt has a clear path. We recently rekeyed a 1960s brick ranch on 167th Street where the homeowner had just inherited the property from her parents. The original Kwikset deadbolts had never been replaced, and the door frames had settled, making the bolts bind. We swapped in Schlage B60N deadbolts and carefully enlarged the strike plates to ensure smooth operation, then set her up with a keyless entry for her rental tenant. Smart lock installation on these homes runs $220-$420. Call (844) 321-2640 to schedule - we’ll assess your frame condition and quote flat.
Yes - this is a specialized service we provide that most Harvey- or Dolton-focused competitors do not. The Cook County Fifth Municipal District Courthouse on 165th Street draws law practices, bail-bond offices, and county facilities that need restricted keyways, master key systems, and audit-trail access control. We install Medeco and Mul-T-Lock key-control systems that limit duplication to authorized signatures, and we maintain the key records per your compliance requirements. Call (844) 321-2640 - we’ll review your facility’s needs and quote upfront.
Rekey between every tenant, and consider upgrading to keyless entry if turnover exceeds once per year. Markham’s rental market moves fast, and original 1960s-1970s locksets wear quickly under frequent rekeying. After three or four rekeys, the keyway is often too oval to hold pins securely. We inspect on each visit and tell you honestly when rekeying is no longer the economical choice. Standard rekeying is $25-$45 per cylinder. Call (844) 321-2640 - we’ll check your hardware condition and advise.
Schlage B60N and Medeco Maxum deadbolts with solid brass bolts handle Cook County’s temperature swings better than economy-grade locks with hollow zinc bolts. The critical factor for Markham’s unheated side entries is the door prep - a properly aligned strike plate prevents the bolt from binding when the frame swells. We also recommend electronic locks for frequently used side doors; no keyway means no ice intrusion. Premium deadbolt installation runs $280-$420. Call (844) 321-2640 for a specific recommendation based on your door’s exposure.
Usually yes, if the door prep is standard 2-1/8″ bore and the frame can accept a modern strike plate. Markham’s 1970s locksets were often installed with smaller bores or thinner faceplates, so we sometimes need to enlarge the door prep and adjust the frame. We handle this in one visit, clean and painted to match. Keyless entry installation with frame modification typically runs $180-$320. Call (844) 321-2640 - describe your current lockset and we’ll tell you exactly what’s involved.
