Call (844) 321-2640 - a live person answers, day or night, including holidays.
Frankfort Square isn’t a place you pass through on the way somewhere else. It’s a community of long-settled neighborhoods where people know their neighbors and stay put. That means we see the same homes again and again - not because our work failed, but because 1970s and 1980s locksets eventually do. We know the tract-home layouts, the original hardware, and the particular problems Will County’s clay soils and freeze-thaw cycles create for doors in ZIP 60423. That local knowledge saves you time and gets the job done right the first time.

Our Residential Locksmith Services in Frankfort Square
Lock Change
Sometimes a lock is too far gone to save. Original builder-grade knob-and-deadbolt combos on Frankfort Square’s 1970s-1990s homes were never meant to last forty-plus years. The cylinders corrode, the keyways wear to obsolescence, and the internal wafers or pins stop aligning. A typical lock change in Frankfort Square runs $140-$220 per door, including a new Grade 2 deadbolt and matching passage knob. We carry Schlage, Kwikset, and Medeco on every truck, so you’re not waiting for parts.

Residential Lockout
Locked out in Frankfort Square? We arrive fast, and we open the door without destroying your lock. Most lockouts in ZIP 60423 resolve in under 20 minutes. Standard residential lockout service is $89-$129 during regular hours. Late-night and holiday calls are available at the same flat-rate structure - we tell you the exact price before we head out. If your lock is original to a 1980s raised-ranch and we discover it’s failing during the entry, we’ll explain your options before doing any additional work.

Deadbolt Installation
This is where Frankfort Square’s housing stock demands real expertise. Those hollow-core steel entry doors, common on ranches and split-levels near Indian Boundary and throughout the 60423 subdivisions, shift with the clay soils. A deadbolt installed without accounting for frame settlement will bind, stick, or fail to throw fully. We were called to a raised-ranch on Pinewood Lane where the original Kwikset deadbolt on the steel entry door had seized in the extended strike box after a late-March freeze-thaw swing. The frame had settled a quarter-inch, so we retrofitted a Schlage B560 with an oversized strike plate and shimmed the frame - upgrading the homeowner from a worn, rekeyed builder-grade set to a Grade 2 deadbolt in under an hour. Deadbolt installation in Frankfort Square typically runs $180-$320, depending on door condition and whether frame correction is needed.

Lock Rekey
Moving into a Frankfort Square home? Lost a key? Want one key for every door? Rekeying changes the internal pin configuration so old keys no longer work - far cheaper than replacing hardware. Most Frankfort Square rekeys run $25-$45 per lock cylinder, with a trip charge of $69-$89. We can often match older Schlage or Kwikset keyways even when the original key is missing, though obsolete keyways on 1970s originals sometimes require hardware replacement. We’ll tell you which before we start.

Window Lock & Door Reinforcement
The interior garage man door on 1970s-80s Frankfort Square homes is routinely the last door to be 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. Door reinforcement includes strike-plate upgrades with 3-inch screws into framing, jamb shields, and proper deadbolt installation. A full reinforcement package for a Frankfort Square garage man door runs $220-$380. Window locks and sash stops are $15-$35 per unit installed.

Trusted Brands We Service in Frankfort Square
We stock and install Schlage, Kwikset, and Medeco on every service vehicle covering Frankfort Square. That means no waiting for parts on standard jobs. For specialty requests, we also work with Yale, Mul-T-Lock, Abloy, Baldwin, and Sargent. The right lock goes on the right door - not just whatever was left on the truck from the last call. On a shifted 1980s steel frame near Braemar or Pinewood, a Grade 2 Schlage B560 with an adjustable strike often outperforms a more expensive lock poorly fitted. We match the hardware to your door’s actual condition, and we explain why.
Common Residential Locksmith Problems We See in Frankfort Square Homes
- Original builder-grade knob-and-deadbolt combos keyed to obsolete keyways. These 1970s-80s locksets corrode internally, keys wear to mismatched profiles, and many locksmiths lack the blanks or pin kits to service them. We carry legacy keyways, but when corrosion has destroyed the cylinder, replacement is the only honest answer.
- Deadbolt bolts sticking in expanded strike boxes after freeze-thaw swings. Will County’s late fall and early spring temperature drops of 30-40°F in hours cause metal frames to contract around cylinders and strike boxes to deform. We see the spike in these calls every October through March - predictable as the seasons.
- Interior garage man doors with no deadbolt. That single knob-lock between your attached garage and living space is the weakest point in most Frankfort Square homes built before 1990. It’s also the entry point most exploited in local break-ins. Upgrading it is usually a 45-minute job.
- Frame misalignment from glacial clay soil settlement. Frankfort Square’s 1970s-1990s tract homes sit on Will County’s expansive glacial clay soils, causing door frames to shift over decades and making deadbolt binding and strike-plate misalignment far more common than in newer subdivisions in Mokena or Frankfort village. This isn’t a lock problem - it’s a door problem that a skilled locksmith diagnoses and corrects, often without replacing the hardware at all.

FAQs - Residential Locksmith in Frankfort Square
It’s almost always frame settlement combined with freeze-thaw cycling. Will County’s expansive glacial clay soils shift your door frame over decades, and 30-40°F temperature swings from October through March cause metal to contract around the deadbolt bolt. The strike box expands, the bolt no longer slides cleanly, and you’re fighting the lock every morning. We correct the frame alignment and upgrade the strike hardware - usually in a single visit. Call (844) 321-2640 for a free assessment.
Yes, if it’s still a single knob-lock without a deadbolt. That’s the most common security gap we find in 1970s-80s Frankfort Square homes, and it’s the entry point most exploited in local break-ins. A Grade 2 deadbolt with reinforced strike plate takes about 45 minutes and runs $180-$280. We can match it to your front door key so you’re not carrying another one. Call (844) 321-2640 to schedule - estimates are free.
Yes, if the cylinders are in serviceable condition. Most Schlage locks from the 1980s and 1990s found in Frankfort Square homes can be rekeyed to a single keyway for $25-$45 per cylinder. If the internal pins are corroded or the keyway is worn beyond tolerance, we’ll tell you before we start and quote replacement options. One key for every door is convenient and worth doing right. Call (844) 321-2640 for an exact quote.
On a shifted hollow-core steel door - standard in Frankfort Square’s ranches and split-levels - we typically recommend a Schlage B560 Grade 2 deadbolt. It tolerates minor frame misalignment better than lighter grades, and the adjustable strike plate adapts to settled openings. Medeco offers higher security if you have specific concerns. We never install a lock without checking frame condition first; the best deadbolt fails on a door that won’t close square. Call (844) 321-2640 and we’ll match hardware to your actual door.
We can correct most minor to moderate frame misalignment that affects lock function. Shimming, strike-plate relocation, and oversized hardware often restore proper deadbolt throw without carpentry work. Severe settlement may require a contractor for structural correction, but we’ll diagnose that honestly and show you why. Many Frankfort Square homeowners are surprised to learn their “broken lock” is actually a shifted frame - a fix we handle in under an hour for $180-$320. Call (844) 321-2640 for a free evaluation.
