We provide independent Medeco locksmith service across North Lawndale, from rekeys and cylinder repairs to full high-security retrofits on the neighborhood’s original 1920s mortise locks. What makes our Medeco work different here is simple: we actually stock the rim cylinders, collars, and OEM pin kits that fit greystone door prep, because most standard Medeco hardware doesn’t drop into a century-old mortise pocket without modification. Call (877) 870-5926 and we’ll tell you exactly what your lock needs before anyone rolls a truck.
Why North Lawndale Residents Choose Us for Medeco Service
Medeco isn’t a brand you learn from a video. The Biaxial, Original, M3, and Maxum lines each have their own sidebar geometry, pin tolerances, and key control rules. We’ve serviced all of them in North Lawndale’s two-flats, three-flats, and courtyard buildings long enough to know what fails and why. Neil Broderick, our owner, came up through the vocational program at Kennedy-King College and has been running locksmith calls across this city for the better part of two decades. He’ll tell you the same thing on any job: Medeco sales & service should never be a guessing game. Show up, solve it, move on.
You get that discipline on every call. We’re an independent shop, not a manufacturer affiliate, so our recommendation is based on what your door actually needs, not a sales quota. Whether you need a rekey on a Biaxial cylinder or a fresh Maxum install on a rear gangway gate, we quote the full price on the phone and that price is what you pay.

Common Medeco Locksmith Problems We Solve in North Lawndale
- Keyway fouling in original mortise locks. Decades of dust, coal residue, and general Chicago grit work their way into the keyway, especially in the 1920s greystones that dominate North Lawndale. When freeze-thaw cycles hit, that gunk freezes and your Medeco key won’t seat or turn. We clean the keyway, flush the cylinder, and re-lubricate without damaging the sidebar.
- Worn or bent key pins in high-turnover rental units. North Lawndale has a steady rental market, which means keys get used hard and duplicated by tenants. Worn pins stop engaging the sidebar correctly, so the key spins but won’t throw the bolt. We re-pin with OEM Medeco pins and cut fresh keys to factory spec.
- Deadbolt misalignment from greystone frame warp. Summer humidity swells wood doors and shifts frames in older buildings. A Medeco deadbolt that’s no longer square to the strike plate puts lateral stress on the hardened pins. We re-align the strike, adjust the bolt throw, and get the cylinder operating smoothly again.
- Broken keys snapped inside Medeco cylinders. When a frozen lock or binding bolt meets force, keys snap. We’ve pulled the broken half out of Biaxial, Original, and M3 cylinders across North Lawndale, then re-pinned the lock so the old key no longer works, a real security plus after a break.
- Retrofits that were never done right. A Medeco cylinder installed in a vintage mortise lock without the right collar or backset modification will bind, chew keys, and eventually fail. We correct those installs, often with a custom-machined cylinder collar matched to the door thickness.
Medeco Service in North Lawndale: What Local Conditions Mean for Your Equipment
Here’s the thing most generic locksmith pages won’t tell you about North Lawndale: this neighborhood’s housing stock wasn’t built for modern high-security cylinders. The two- and three-flat greystones and brick courtyard buildings put up between 1890 and 1930 came with mortise locksets, transom windows, and heavy wood or steel entry doors. Those original mortise pockets are deeper and wider than what a standard Medeco cylinder expects. A drop-in install rarely works. We routinely carry an extra set of vintage skeleton keys and mortise-lock parts for the 1920s doors you find along blocks like South Independence Boulevard, because the big-box hardware store a few blocks over doesn’t stock any of it. We also handle Medeco repair in West Garfield Park with the same vintage expertise. For Medeco specifically, that means we machine cylinder collars, fit rim cylinders where the original tubular deadbolt sat, and adjust backset on-site. That’s the difference between a lock that works for a season and one that works for a decade.
Medeco Models & Products We Service in North Lawndale
Our team services the full Medeco lineup you’re likely to find in North Lawndale: the Medeco Original, the Biaxial, the high-security M3, and the newer Maxum series. We use OEM Medeco cylinders and pins whenever they’re available, because that’s what preserves the UL 437 rating and the key control your building relies on. For older Biaxial models where OEM cam assemblies have been discontinued, we keep quality aftermarket springs and cams in stock so repair doesn’t turn into a full cylinder replacement. We’ll always repair first if the sidebar and pins are intact. Replacement only happens when the cylinder body or keyway is physically damaged.
Medeco Service Pricing in North Lawndale
Medeco service in North Lawndale typically runs $95 to $185 for cylinder cleaning, re-pinning, and key cutting, while a full rekey of multiple high-security cylinders ranges from $25 to $60 per lock depending on cylinder type and whether OEM or aftermarket pins are used. Full Medeco cylinder replacement, including the custom collar work common on older greystone doors, generally falls between $165 and $340. High-security key duplication runs $15 to $45 per key. The factors that move your price: door prep condition, cylinder model, and how many locks need work. Call (877) 870-5926 for an exact quote. We give you the full number on the phone, and that’s the number on the invoice.

FAQs – Medeco Locksmith in North Lawndale
Yes, in most cases we can rekey the Medeco cylinder in place, without touching the original mortise lock body. As long as the sidebar mechanism and pins are intact, a rekey restores full security and key control at a fraction of replacement cost. If the mortise body itself is worn beyond repair, we’ll tell you that before doing any work. Call (877) 870-5926 and describe your door, we’ll let you know what’s possible.
Freeze-thaw cycles cause door frames and locks to swell and contract, and that puts pressure on the cylinder interior. In North Lawndale’s older brick and greystone buildings, the freeze-thaw cycle is especially rough on original wood frames, and the moisture gets into the keyway, freezing the pins in place. We provide Medeco repair in Lower West Side with the same weather-hardened approach. A quick on-site cleaning and re-lubrication usually fixes it, but if the frame has shifted, the real fix is a strike plate adjustment so the deadbolt isn’t binding.
We stock Biaxial rim cylinders and the components needed to fit them into original mortise pockets, including custom collars for non-standard door prep. Most off-the-shelf Biaxial cylinders need modification before they’ll seat properly in a greystone’s original mortise lock, and we handle that on-site. If you’re not sure what your door takes, call (877) 870-5926 and describe what you’re looking at, we’ll tell you what fits.
Both offer pick resistance and key control, but they’re different animals. Biaxial has been the workhorse in North Lawndale’s rental buildings for years, with a proven sidebar design and wide parts availability. Maxum is newer, with a hardened steel core and upgraded drill resistance, and it’s a solid choice for a front entry that faces the street or a rear gangway gate that gets hit at night. We install and service both, and we’ll help you choose based on your door prep and actual exposure. Call (877) 870-5926 for a straight recommendation.
Yes. North Lawndale has a large stock of vacant and rehabbed buildings, and securing them properly matters for both safety and code compliance. We also offer Medeco service in McKinley Park and can install or rekey Medeco cylinders on entry doors, rear gangway gates, and coach-house entrances, and we’ll document the work so you have a clear record for inspection. Tell us what the building needs, and we’ll give you a written scope and a flat per-lock price before scheduling. Call (877) 870-5926.
