Fast, Reliable Lock Installation & Rekey Across Mount Prospect
Lock installation and rekeying in Mount Prospect typically runs $89-$340 depending on hardware and labor, with most jobs completed same-day. Our crew covers the full 60056 ZIP code and surrounding Mount Prospect neighborhoods with flat, phone-quoted pricing before any truck rolls.
We’ve worked Mount Prospect’s streets for over 42 years. From the postwar ranches near Lions Park to the garden apartments lining Busse Road and Rand Road, we know the village’s doors, its hardware, and its problems. The aging housing stock here - much of it built between 1948 and 1975 - presents lock challenges that newer suburbs simply don’t have. Wooden frames that have shifted through fifty-plus winters. Builder-grade knob locks from the 1960s still guarding garage side entries. Master-key systems in 1970s apartment complexes that need rekeying every tenant turnover.
We answer calls live, 24/7. No voicemail trees. When you call (844) 321-2640, a real person quotes your real price. That price is the price on the invoice. Period.
Why Strongbox Lock & Safe Co. of Illinois Is Mount Prospect’s Preferred Lock Installation & Rekey Company
Mount Prospect homeowners remember the last time a locksmith quoted $19 on the phone and billed $400 at the door. We built our company as the verifiable alternative. Our Lock Installation & Rekey team quotes flat prices upfront, sends background-checked technicians in uniform who show ID at your door, and backs every job with the 90-Day Done Right Promise - in writing, no paperwork, no arguing.
Our technicians carry Schlage, Kwikset, Medeco, and Yale hardware on every Mount Prospect run. That means most jobs finish in one visit without waiting on parts. We know the village’s freeze-thaw patterns, its alley-load townhome clearances, and the specific failure modes that hit 1960s ranch and split-level homes here. Last winter, we rekeyed a 1960s ranch east of the downtown Metra station where the attached garage side-entry door had a builder-grade knob lock with no deadbolt. We installed a Schlage B60N deadbolt and replaced the worn Kwikset cylinder on the front door, correcting strike-plate misalignment caused by decades of freeze-thaw shifting.
We plan to be serving Mount Prospect in thirty years. We act like it.
Our Lock Installation & Rekey Services in Mount Prospect
Deadbolt Installation
The ranch homes east of the downtown Metra station - Mount Prospect stop on the Milwaukee District Northwest Line - have a known weak point. Their attached garage side-entry doors frequently still carry builder-grade knob locks with no deadbolt, installed in the 1960s. These are known targets. We add Grade 1 or Grade 2 deadbolts to these doors on nearly every job in that pocket of the village. For north-facing exterior doors that take the brunt of Cook County’s winter winds, we spec hardware with adjustable backsets to accommodate frame shift. A typical deadbolt installation in Mount Prospect runs $149-$219, including hardware.
Smart Lock Installation
Mount Prospect’s 1960s garden apartment complexes and postwar ranches can absolutely take smart locks - but the installation requires more than swapping a deadbolt. Older wooden frames often need reinforcement. Strike plates need repositioning after decades of seasonal movement. We install Schlage Encode, Yale Assure, and Kwikset Halo models with Wi-Fi or Z-Wave connectivity, and we make sure your 50-year-old door can actually support the hardware. Smart lock installation in Mount Prospect typically costs $249-$389, including the lock and labor. We handle the app setup and show you how it works before we leave.
Keyless Entry & Keypad Lock Installation
For the garden apartments along Busse Road and Rand Road, keyless entry eliminates rekeying costs every tenant turnover. We install standalone keypad deadbolts and hardwired access control systems for multi-unit buildings. Property managers in Mount Prospect call us specifically for this - the combination of aging master-key systems and frequent turnover makes keypad locks a practical upgrade. Keypad lock installation runs $199-$329 for residential, with commercial multi-unit systems quoted individually.
Biometric Lock & Electronic Lock Installation
Biometric and electronic locks suit Mount Prospect homeowners who want keyless convenience with higher security. We install fingerprint-enabled deadbolts and electronic mortise locks for residential and light commercial use. These systems require precise door prep in older frames - something our crew handles daily in Mount Prospect’s postwar housing stock. Electronic lock installation typically runs $279-$449 depending on the hardware grade and door condition.

Trusted Brands We Service in Mount Prospect
We stock and install Schlage, Kwikset, Medeco, and Yale hardware on every Mount Prospect service vehicle. That matters when your lock fails at 10 PM on a February night and you need same-day resolution. We don’t show up with whatever’s on the truck and hope it fits. We carry the right lock for your specific door, frame, and security need. For the village’s aging Kwikset and Schlage cylinders - still common in 1960s and 1970s installations - we keep replacement cores, tailpieces, and strike plates in stock. Most rekeys and cylinder replacements finish in under 45 minutes.
Common Lock Installation & Rekey Problems We See in Mount Prospect Homes
- Deadbolt throw misalignment on north-facing exterior doors after hard freezes. Mount Prospect’s extreme freeze-thaw cycles cause wooden and aluminum frames to contract enough that deadbolt throws no longer align with strike plates. This spikes lockout calls from December through February, especially on homes with original 1960s frames.
- Strike-plate screws stripping in 50+ year old wooden frames. The soft pine and fir used in postwar construction doesn’t hold screws after decades of seasonal stress. We often need to install longer screws into structural framing or replace the entire strike plate with a reinforced model.
- Alley-load townhome doors in tight clearances. Mount Prospect’s denser pockets near downtown have narrow alley access where oversized tool kits don’t fit. Our technicians carry compact installation gear specifically for these spaces.
- Worn master-key cylinders in 1960s garden apartment complexes. The Schlage and Kwikset hardware in buildings along Busse Road and Rand Road has been master-keyed and rekeyed so many times that cylinder tolerances have degraded. These need full cylinder replacement, not just another rekey.

Your deadbolts stick because fifty-plus years of Cook County freeze-thaw cycles have shifted your wooden door frame, misaligning the deadbolt throw with the strike plate.

We correct this by repositioning or replacing the strike plate and sometimes adjusting the door hanging. Call (844) 321-2640 - we’ll diagnose it over the phone and quote flat.
