Why Chicago Residents Choose Us for Medeco Service
Daniel Novak grew up in Astoria, Queens, two blocks from the elevated N train, and has been working New York City doors, deadbolts, and cylinders for going on two decades. He learned the trade at Queensborough Community College, then apprenticed under a retired locksmith who serviced Midtown commercial accounts. That background matters in Chicago because the city’s housing stock demands a locksmith who knows legacy mortise hardware. Two-flats, three-flats, greystones, and courtyard buildings built between 1890 and 1930 still run on original or period mortise locks, and a surprising number of those were retrofitted with Medeco cylinders decades ago. We understand that equipment. We carry genuine Medeco OEM pin kits, sidebar parts, and key blanks, and our vans are stocked for the specific Medeco conversions found block after block in neighborhoods like Logan Square, Bridgeport, Pilsen, and Wicker Park. Every visit includes a documented photo record and a background-checked, uniformed technician. The name on the van is the same name on the invoice.
Common Medeco Locksmith Problems We Solve in Chicago
- Frozen Medeco cylinders on two-flats and greystones. Lake-effect moisture infiltrates exterior cylinders overnight during deep freezes, and the factory lubricant thickens until the sidebar pins bind. The key won’t turn. We warm the cylinder face carefully, confirm the pins are moving, and rekey if the tenant or owner wants a fresh key system. This happens every winter in Chicago, and it’s rarely a reason to replace the cylinder.
- Worn or sheared sidebar pins in original 1910s-1930s mortise locks. Intermittent key insertion failures or a key that refuses to turn usually mean the sidebar pins have worn past tolerance. On legacy Medeco Originals in old greystone mortise bodies, we’ll assess whether the cylinder can be economically serviced or should be upgraded to a current Medeco³ or KeyMark, reusing the mortise body where possible.
- Freeze-thaw deadbolt misalignment. Chicago’s limestone and brick doorframes shift seasonally. A perfectly functioning Medeco deadbolt throws short of the strike plate every spring because the jamb moved over winter. We adjust the strike, not the cylinder. In the bungalow belt, this is so predictable we check alignment as standard on every Medeco service call.
- Corroded rim cylinders on bungalow belt back doors. Decades of road-salt spray from alley parking accelerates brass corrosion and seizes pin chambers. When a Medeco rim cylinder is deeply corroded at the plug face, rekeying isn’t economical. We’ll say so plainly and quote a replacement cylinder in writing before any work begins.
- Lost keys on high-security cylinders. Without the original key, rekeying a Medeco cylinder means shimming or picking the sidebar mechanism, not just the pin stack. We carry the specialized tools for Medeco Originals, Biaxials, and Medeco³ cylinders, so a lost key doesn’t mean replacing an expensive mortise body.
Medeco Service in Chicago: What Local Conditions Mean for Your Equipment
Chicago’s 80,000-plus bungalows form a housing segment that behaves differently from anything a suburban locksmith sees. These Jefferson Park, Portage Park, and Clearing homes were built largely between the 1910s and 1940s with remarkably uniform hardware, and during the 1970s and 1980s, the same handful of contractors installed Medeco rim or mortise cylinders as aftermarket security upgrades across block after block. The practical result for a Medeco owner is this: one well-stocked van carrying that era’s Medeco Original and Biaxial pinning kits can rekey an entire neighborhood without a warehouse run. We built our Chicago van inventory around that reality. It’s why we can often rekey a Medeco cylinder on the same day in the bungalow belt, even when the key is lost and the cylinder hasn’t been serviced in thirty years, thanks to our Lock Installation & Rekey in Chicago setup. A generic Medeco page won’t tell you that. A generic Chicago locksmith page can’t. On a February call to a greystone two-flat on North Oakley in Logan Square, our tech found the street-level owner’s unit locked out because the original Medeco Biaxial mortise cylinder on the vestibule door had frozen solid from overnight lake moisture. After warming the cylinder face with a portable heat pack, we confirmed the sidebar pins were moving, rekeyed it to a new Medeco³ key at the tenant’s request, and adjusted the deadbolt strike by an eighth of an inch to compensate for the freeze-shifted limestone jamb. That’s what Medeco service looks like in Chicago.
Medeco Models & Products We Service in Chicago
We service the full Medeco line: Medeco Original (Classic) mortise and rim cylinders, Medeco Biaxial (BX/BiaXial) high-security cylinders, Medeco Medeco³ (M3) and M3 Logic cylinders, and Medeco KeyMark removable core systems. We stock genuine Medeco OEM pin kits, sidebars, and key blanks because aftermarket Medeco-style parts fail to meet the tolerances that give the cylinders their drill and pick resistance. Substituting pins or sidebars from generic high-security kits is something we never do. For legacy Medeco Originals beyond economical repair, such as cylinders with deeply corroded plug faces, we’ll recommend an upgrade to a current Medeco³ or KeyMark cylinder and reuse the existing mortise body where possible. Medeco sales & service is a core part of our work, and we price every job in writing before touching a cylinder.
Medeco Service Pricing in Chicago
You’ll get a firm price on the phone before anyone is dispatched. We don’t quote a teaser rate and revise it at the door. Here’s what Medeco work typically runs in Chicago:
- Medeco rekey (per cylinder): $35-$65, depending on model and condition
- Medeco mortise cylinder replacement: $120-$220, including OEM cylinder and labor
- Medeco rim cylinder replacement: $95-$175
- Lost-key rekey service call (first cylinder): $85-$140, including the service call
- Deadbolt strike adjustment for freeze-thaw misalignment: $45-$75
- Master key system setup (per building, up to 6 cylinders): $300-$550
What drives the price is the cylinder model, whether we’re rekeying or replacing, and how many cylinders are involved. A greystone two-flat with two Medeco mortise cylinders and a rim cylinder on the vestibule door will cost more than a single bungalow back door cylinder. Every estimate is free. Call (331) 310-8471 for an exact quote, and the price we give you is the price on the invoice. That’s not a sales line. It’s the rule we’ve operated under since 2002.

FAQs - Medeco Locksmith in Chicago
If you have an authorized key card or the key itself is not marked “Do Not Duplicate,” we can cut Medeco keys on our factory-cut blanks. We carry the sidebar code machines for Original, Biaxial, and Medeco³ systems. Many Chicago condo boards require written authorization from the association or management company before we cut a copy. Bring that authorization, and we’ll cut the key while you wait. Call (331) 310-8471 and we’ll tell you exactly what documentation we need.
Usually not. What you’re describing is often a freeze-thaw alignment problem, not a cylinder failure. Chicago’s winter temperature swings shift the doorframe, and the deadbolt starts binding against the strike plate. We can adjust the strike and lubricate the cylinder with a cold-rated lubricant, and the problem typically resolves. If the cylinder itself has internal wear, we’ll tell you that too. Call (331) 310-8471 and we’ll quote the adjustment over the phone.
We use specialized Medeco tools to defeat and remove the cylinder, then decode or replace the sidebar mechanism and rekey to new keys. It’s more involved than a standard Kwikset rekey, but it’s routine work for us. We carry the tooling for Medeco Original, Biaxial, and Medeco³ cylinders in our Chicago vans, so a lost key doesn’t mean replacing the mortise body. Call (331) 310-8471 for a written quote before we send anyone out.
In most cases, it’s realistic. The Medeco³ cylinder is dimensionally compatible with many legacy mortise bodies, so we can pull the old Original cylinder, install the Medeco³, and key it to a new system without replacing the entire mortise lock. The exceptions are cases where the mortise body itself is worn or the lock case is a non-standard size. We’ll assess it on site and tell you honestly whether a conversion or a full replacement makes sense. Call (331) 310-8471 and we’ll walk through what your building likely has.
Yes. We build and service Medeco master key systems for multi-address buildings in Chicago. We can create a master, submaster, and per-unit hierarchy using Medeco³ or KeyMark, and we document every key issued. Each cylinder gets rekeyed or replaced to the new hierarchy, and we leave a written key schedule with the landlord. For a courtyard building with, say, six units and a common entrance, pricing typically starts around $300 and depends on cylinder count. Call (331) 310-8471 for a flat quote on your building.
