We’ve been working in Frankfort Square’s 60423 zip code for decades. The raised-ranches along Sauk Trail, the split-levels near the Pinewood subdivision, the ranches tucked behind St. Francis Road - we know the doors, the frames, and the problems they develop. Will County’s glacial clay soils don’t forgive old hardware, and Frankfort Square’s 1970s-1990s tract homes have had plenty of time to show it. When your deadbolt binds every October or your key snaps in a corroded cylinder, you want someone who understands why it happened, not just how to fix it.

Our Lock Installation & Rekey Services in Frankfort Square
Smart Lock Installation
Smart lock installation in Frankfort Square runs $180-$340 for most residential doors, including WiFi-enabled deadbolts from Yale and Schlage. The challenge on older Frankfort Square homes isn’t the lock - it’s the door. Hollow-core steel entry doors from the 1980s often have inconsistent bore holes and shifted frames that won’t accept a smart deadbolt without shimming or frame adjustment. We measure first, quote flat, and install once. You’ll get keyless entry, app control, and the ability to issue temporary codes for visiting family or contractors. Done right, and backed in writing.

Keyless Entry & Keypad Lock Installation
Keypad lock installation in Frankfort Square typically costs $150-$280, a popular choice for homeowners who want to stop hiding keys under the mat. We install Medeco and Schlage keypads that stand up to Will County’s freeze-thaw abuse - no batteries dying from cold drafts, no buttons sticking after a wet spring. For the garage-to-house man door that so many Frankfort Square homes still secure with only a knob lock, a keypad deadbolt is often the simplest security upgrade we offer. No more fumbling for keys with groceries in hand.

Biometric Lock Installation
Biometric locks - fingerprint readers - start around $280 installed in Frankfort Square. These suit homeowners who want maximum control over who enters. We see growing interest from Frankfort Square’s long-term residents who are aging in place and want to eliminate key management entirely. Installation on older doors requires careful alignment; shifted frames from clay soil settlement can misalign fingerprint sensors just as they do deadbolts. We address the frame first, then install the hardware. The price we quote is the price you pay.

Key Duplication
Key duplication in Frankfort Square runs $4-$12 per key for standard residential keyways, $15-$35 for high-security keys from Medeco or Mul-T-Lock. Many Frankfort Square homes still carry original Kwikset or Schlage keys from the 1980s or 1990s - keyways that are increasingly obsolete. We duplicate on-site from our mobile workshop and can identify when your keyway is discontinued, giving you the option to rekey to a current standard before you can’t get copies anymore. Seniors and veterans receive 5% off every key duplication order.

Trusted Brands We Service in Frankfort Square
We install and service Medeco, Yale, Baldwin, and Mul-T-Lock hardware in Frankfort Square, plus Schlage, Abloy, Kwikset, and Sargent. Our trucks carry the full range, so the right lock goes on your door, not just what was on the shelf. For Frankfort Square’s older homes, we often recommend Yale or Schlage Grade 2 deadbolts for exterior doors - they fit existing bore holes without drilling, hold alignment better through seasonal frame movement, and resist the corrosion that kills cheaper hardware in Will County’s wet winters. We stock parts locally for same-day turnaround on most repairs.
Common Lock Installation & Rekey Problems We See in Frankfort Square Homes
- Corroded cylinders from freeze-thaw cycling. Will County’s temperature swings of 30-40°F in hours cause condensation inside lock cylinders. Original builder-grade Kwikset and Schlage hardware from the 1980s corrodes from the inside out, leading to seized cylinders and keys that snap off. We extract broken keys and upgrade to corrosion-resistant brass or stainless cylinders.
- Deadbolt binding from frame settlement. Frankfort Square’s glacial clay soils expand and contract with moisture, shifting door frames over decades. Strike plates move. Deadbolts that slid freely in summer jam tight by November. On a recent job in the Pinewood subdivision, we rekeyed and upgraded the original Kwikset knob-and-deadbolt combo on a 1985 raised-ranch where the strike plate had shifted a quarter-inch from foundation settling, causing the deadbolt to bind every fall freeze-thaw cycle.
- Obsolete keyways with no replacement blanks. Many 1970s-90s Frankfort Square homes carry original keyways that manufacturers no longer support. You discover this when your last key breaks and no one can cut a copy. We rekey to current standards - usually Schlage SC1 or Kwikset KW1 - so you’re never stranded.
- The garage man door with no deadbolt. The interior door from attached garage to living space on 1970s-80s Frankfort Square homes is routinely the last door upgraded, commonly still on a single knob-lock with no deadbolt. It’s the most frequently cited security gap when homeowners finally call us after a neighborhood break-in. We install Grade 2 deadbolts on these doors as standard practice.

FAQs - Lock Installation & Rekey in Frankfort Square
Will County’s freeze-thaw cycling causes your metal door frame to contract around the deadbolt bolt, while the strike box expands slightly from moisture. On Frankfort Square’s 1970s-1990s homes, decades of clay soil settlement have already shifted strike plates out of alignment, so the seasonal movement compounds the problem. We adjust or relocate the strike plate and often upgrade to a deadbolt with more generous clearance. Call (844) 321-2640 for a free look - estimates are free.
Rekey if the hardware is solid and you simply need new keys - typically $19-$29 per cylinder. Replace if the lock shows corrosion, wobble, or inconsistent operation, which is common on original Frankfort Square builder-grade hardware after 40 years of freeze-thaw exposure. We inspect on-site and give you a straight recommendation. Call (844) 321-2640 to schedule.
Yes, we install smart locks on Frankfort Square’s 1970s-90s doors regularly. The critical factor is door and frame condition, not age. Hollow-core steel doors often need bore-hole adjustment, and shifted frames require shimming for proper deadbolt alignment. We handle all of this in one visit. Smart lock installation in Frankfort Square runs $180-$340. Call (844) 321-2640 for an exact quote - estimates are free.
The garage-to-house man door with only a knob lock and no deadbolt. On 1970s-80s Frankfort Square homes, this door was built to code of its era but falls short of modern security standards. Homeowners often overlook it until after a neighborhood break-in. We install Grade 2 deadbolts on this door as a routine upgrade, usually for $89-$140. Call (844) 321-2640 to close this gap.
A typical Frankfort Square home with three exterior doors (front, back, garage man door) costs $57-$87 to rekey all cylinders to a single key. If the garage man door has no deadbolt and you add one, the total runs $146-$227. Most Frankfort Square homeowners rekey after moving in, after a lost key, or when transitioning from rental to owner-occupancy. Call (844) 321-2640 for an exact count - estimates are free.
