Why Strongbox Lock & Safe Co. of Illinois Is Mount Greenwood’s Preferred Lock Installation & Rekey Company
We’ve served Chicago-area communities for over 42 years, and Mount Greenwood has been a core part of our territory from the start. Our customers here are different from what we see in neighboring suburbs. Many are active or retired CPD officers and CFD firefighters who know exactly what they want: Medeco or Mul-T-Lock cylinders, bump-resistant deadbolts, and every lock rekeyed the day they get the keys. We don’t need to explain why rekeying matters. These customers ask about pinning configurations and key control systems before we unload our tools.
That security literacy raises the bar for our work, and we meet it. Our technicians are background-checked, uniformed, and present ID at every door. We quote a flat price on the phone before the truck rolls, and every job carries our 90-Day Done Right Promise in writing. If something isn’t right, we come back. No paperwork, no arguing.
Calls are answered by a live person 24/7, including nights, weekends, and holidays. No voicemail trees. No callback queues. For Mount Greenwood residents, that reliability matters, especially when you’re standing outside a frozen lock in January or need your locks changed before a closing.
We recently rekeyed all three deadbolts in a 1950s brick bungalow on South Kedzie Avenue for a retired firefighter who had just purchased the home. The original Kwikset hardware hadn’t been changed since the 1970s, and the steel jambs required careful drilling to match the new Medeco cylinders. We installed a smart lock with battery backup for the side door, giving our customer confidence during his annual Florida trip.
Our Lock Installation & Rekey Services in Mount Greenwood
Smart Lock Installation
Smart lock installation in Mount Greenwood typically costs $280-$450, including the device and labor. For the neighborhood’s many seasonal residents who head to Arizona or Florida for months at a time, we recommend models with battery backup and Wi-Fi connectivity so you can verify your doors are locked from anywhere. The heavy masonry construction in Mount Greenwood’s brick bungalows means we often need specialized anchors for smart lock mounting plates, especially when the original steel jamb has shifted slightly over decades. We handle that adjustment without damaging your frame.
Keyless Entry and Keypad Lock Installation
Keyless entry systems run $220-$390 installed in Mount Greenwood, with keypad locks at the lower end and connected systems at the higher end. These are popular with older homeowners who don’t want to fumble for keys, and with families who need to grant temporary access to caregivers or house-sitters. On 111th Street and the surrounding blocks, we’ve installed dozens of keypad deadbolts for retired officers who want quick entry in full gear or simply prefer not to carry keys on morning walks. We program everything before we leave, and we show you how to add or delete codes.
Biometric Lock Installation
Biometric locks, using fingerprint recognition, start around $340 for installation in Mount Greenwood and range up to $520 for commercial-grade units. These are less common in residential settings here, but we do install them for customers who want the highest level of access control. The technology has improved significantly; modern biometric locks handle the temperature swings that affect Mount Greenwood’s exposed entry doors better than earlier generations. We typically recommend them for side or rear doors where convenience matters most.
Medeco and Mul-T-Lock Cylinder Upgrades
High-security cylinder upgrades are our most requested service in Mount Greenwood outside of standard rekeying. A Medeco or Mul-T-Lock cylinder installation runs $180-$340 per door, depending on whether we’re retrofitting existing hardware or installing new. These cylinders use restricted keyways and pick-resistant pin configurations that meet the security standards this neighborhood’s law enforcement families expect. We stock both brands locally, so most upgrades are completed same-day without waiting for parts.

Trusted Brands We Service in Mount Greenwood
We install and service Schlage, Medeco, Mul-T-Lock, Yale, Baldwin, and Kwikset throughout Mount Greenwood. Our truck carries the cylinders, latches, and strike plates most common to the 1940s-1960s housing stock here, so we rarely need to make a second trip. For Medeco and Mul-T-Lock upgrades, we maintain local key blanks and pinning kits specific to those restricted keyways. That inventory means a rekey that might take a week elsewhere gets done while you wait. We also work with Abloy, Sargent, and other premium brands for customers with specialized requirements.
Common Lock Installation & Rekey Problems We See in Mount Greenwood Homes
- Steel frame expansion causing bolt misalignment. Original steel door frames in 1940s-60s bungalows expand and contract with Chicago’s freeze-thaw cycles, slowly throwing deadbolt alignment off and creating lockouts that homeowners mistake for lock failure. We diagnose this with a simple gap check and realign the strike plate rather than replacing a perfectly good lock.
- Frozen exterior cylinders on exposed brick bungalows. Exterior lock cylinders ice up during hard winter freezes, especially on unshaded south-facing doors, requiring de-icing service calls that are rare in suburbs without this brick-bungalow housing stock. We carry graphite lubricants and de-icing solvents designed for metal cylinders, not the WD-40 that makes the problem worse.
- Damaged high-security pins from DIY rekeying attempts. Security-literate former officers often attempt DIY rekeying with Medeco or Mul-T-Lock cylinders but damage the pins, leading to intermittent jamming that only a professional can diagnose and fix. We see this several times a year and can usually salvage the cylinder rather than replacing it entirely.
- Aging Kwikset and Yale hardware never rekeyed since original installation. Many Mount Greenwood homes still run the same locks that were installed when Truman was president. The internal springs fatigue, keys wear to odd profiles, and the locks become easier to force. A full rekey with new pins and springs restores security without replacing the exterior hardware.

FAQs - Lock Installation & Rekey in Mount Greenwood
Yes. We install smart locks on original steel jambs regularly in Mount Greenwood, using specialized anchors and careful drilling techniques that preserve the jamb’s integrity. The steel is actually more durable than modern aluminum frames; the challenge is precise alignment, which our technicians handle with jamb-adjustment shims rather than forcing the hardware. Call (844) 321-2640 for a free estimate - we’ll assess your specific door and quote a flat price before we arrive.
It’s usually the frame. Chicago’s freeze-thaw cycles cause steel door frames to expand and contract, gradually shifting the strike plate alignment until the bolt drags or won’t throw fully. We see this constantly on 111th Street and throughout Mount Greenwood’s brick bungalow blocks. The fix is a strike-plate realignment, not a new lock. We diagnose this in minutes and adjust it on the spot. Call (844) 321-2640 - we’ll confirm over the phone whether it sounds like alignment or cylinder wear.
Typically 45-60 minutes for three deadbolts, assuming standard Kwikset or Yale hardware in good condition. If the internal springs are fatigued or the cylinders show corrosion from decades of Chicago humidity, we may recommend replacing the hardware entirely. We stock the common sizes for Mount Greenwood’s 1940s-1960s homes, so most jobs finish in one visit. Call (844) 321-2640 to schedule - we often accommodate new homeowners on short notice.
A smart lock with battery backup and remote access is the most valuable upgrade for seasonal residents. You can verify locks from Arizona, grant temporary codes to house-sitters or maintenance workers, and receive alerts if someone attempts entry. We also recommend rekeying any cylinders that haven’t been changed recently and installing bump-resistant deadbolts on secondary doors. Call (844) 321-2640 for a pre-departure security review - we’ll prioritize the upgrades that matter for your specific situation.
Yes, rekeying after divorce or estate transfer is unusually common in Mount Greenwood because of the high concentration of security-aware law enforcement and fire families who understand exactly what compromised key control means. We can dispatch an unmarked vehicle upon request and schedule appointments at times that minimize attention. All work is confidential, and we rekey every cylinder so previous keys no longer function. Call (844) 321-2640 - mention your preference for discretion when you call, and we’ll handle the scheduling accordingly.
