Trusted Lock Installation & Rekey for Illinois Homeowners
Our Best Lock Installation & Rekey in Illinois, IL typically costs between $89 and $340 depending on the hardware and complexity, and most jobs are completed in a single visit the same day you call. Strongbox Lock & Safe Co. has served Illinois homeowners for over 42 years with flat prices quoted on the phone before any work begins. We’re the company that shows up when we say we will, uniformed technician with ID in hand, and we back every lock installation and rekey with our written 90-Day Done Right Promise.
We’ve heard too many stories from Illinois homeowners who answered a $19 service-call ad and watched the bill climb to $400 or more once the technician was inside. That is not how we work. When you call (844) 321-2640, a live person answers - every time, including nights, weekends, and holidays - and we quote your price upfront. The number we give you is the number on the invoice. Phil Eckhardt built this company on that principle, and we have not wavered from it in four decades of serving families across Illinois.
Whether you have just bought a home in Chicago and need every lock rekeyed, you are upgrading to a smart lock in Bridgeport, or you are replacing worn hardware in a century-old bungalow in McKinley Park, our Lock Installation & Rekey in Near South Side team carries the right products and the expertise to match. Our technicians are background-checked, uniformed, and trained to work with everything from traditional pin-tumbler cylinders to biometric access systems. And because we stock premium hardware from Schlage, Mul-T-Lock, Abloy, and other leading brands, we rarely need to make a second trip.
What Our Lock Installation & Rekey Service Includes
Smart Lock Installation
Smart locks connect to your home’s Wi-Fi or Bluetooth, letting you lock and unlock doors remotely, issue temporary codes to visitors, and receive alerts when someone enters. Illinois homeowners who travel frequently or have adult children coming and going find them especially practical. We install and configure smart locks from Schlage, Yale, and other major manufacturers, and we make sure you understand the app before we leave - no handing you a manual and wishing you luck.

Keyless Entry
Keyless entry systems eliminate the need for physical keys entirely, using codes, cards, or fobs instead. These are popular for side doors, home offices, and rental properties throughout Illinois where key tracking becomes a headache. We assess your door’s condition and frame alignment first, because a keyless lock installed on a warped or poorly hung door will fail prematurely. Our flat-price quote includes that assessment, the hardware, and the installation.

Keypad Lock
Keypad locks let you enter a numeric code to unlock the door, and most models allow multiple user codes for family members or service providers. In Illinois, where winters can dip well below freezing, we specify keypad models rated for our temperature extremes - cheaper units from big-box stores often malfunction after a single harsh season. We stock and install commercial-grade keypad locks that hold up to real Illinois weather.

Biometric Lock
Biometric locks use fingerprint recognition to grant access, offering convenience for homeowners who do not want to carry keys or remember codes. These systems have improved dramatically in reliability, and we now install them regularly for Illinois clients with arthritis or vision concerns that make traditional locks difficult to operate. We calibrate the scanner for multiple family members and show you how to add or remove users.

Electronic Lock
Electronic locks encompass any lock powered by electricity or batteries, including keypads, smart locks, and card readers. If you are unsure which electronic system fits your Illinois home, we will walk you through the options on the phone or during our free estimate. We also handle the wiring and power considerations that many homeowners overlook - a dead battery should not leave you stranded outside your own door.

Key Duplication
Key duplication at Strongbox is done on precision machines calibrated to factory specifications, not the worn-down cutters you find at self-service kiosks. We duplicate standard keys, high-security keys including Mul-T-Lock and Abloy, and restricted keyway blanks that require authorization. For Illinois homeowners rekeying an entire property, we can cut and test every new key on-site before we leave.

Brands We Service for Lock Installation & Rekey
We have installed and serviced thousands of Schlage locks across Illinois, from their residential deadbolts to their commercial-grade interconnected locksets. Our technicians carry Schlage’s most common cylinders and latch assemblies on every truck, which means we can often rekey or replace a Schlage lock without ordering parts. We also work extensively with Mul-T-Lock, the Israeli manufacturer whose pick-resistant pin-in-pin design is specified by many Illinois businesses and security-conscious homeowners. Our Mul-T-Lock training is factory-certified, and we stock their high-security key blanks.
Abloy’s disc-detainer mechanism, nearly impossible to pick with conventional tools, is another Douglas Lock Installation & Rekey specialty we have developed over decades of serving Illinois clients. We have rebuilt Abloy cylinders for banks, installed their padlock lines for industrial facilities, and rekeyed their residential Protec2 systems for homeowners in Chicago’s historic districts. Sargent’s commercial-grade mortise locks and exit devices are familiar territory as well - we maintain Sargent hardware for schools, churches, and office buildings throughout the state. Whether you have Schlage, Mul-T-Lock, Abloy, Sargent, or any other make, we can help.
Signs You Need Lock Installation & Rekey Right Now
- The key sticks or requires jiggling. A key that no longer turns smoothly indicates worn pins, a damaged keyway, or internal corrosion. In Illinois, where humidity swings from summer highs to winter lows, we see this frequently in older homes near the lakefront - and it only gets worse until the key breaks off entirely or the lock seizes.
- You have lost track of who has copies of your keys. Previous owners, contractors, housekeepers, dog walkers, and adult children’s former partners may all possess working keys to your home. Rekeying changes the internal pin configuration so old keys no longer function, giving you complete control over access without replacing the hardware.
- The lock hardware is loose, misaligned, or visibly damaged. A deadbolt that does not fully extend into the strike plate, a handle that wiggles in its mounting, or visible cracks in the lock body all compromise security. We inspect the door and frame as well as the lock itself, because hardware installed on a structurally compromised door will fail regardless of the lock’s quality.
- You have experienced a break-in or attempted break-in. Even if the lock still functions, forced entry attempts can damage internal components in ways not visible from outside. We disassemble and inspect the mechanism, replace any compromised parts, and can upgrade to higher-security hardware if the existing lock proved too easy to defeat.
- Your locks are more than 15 years old and original to the house. Lock technology and security standards have advanced significantly. Older locks often lack pick resistance, drill resistance, and bump-key protection that even mid-grade modern hardware provides. For Illinois homeowners planning to stay put, upgrading now means not worrying about it again for decades.
Our Lock Installation & Rekey Process - Step by Step
- 1
Call for your flat-price quote. When you dial (844) 321-2640, a live person answers - no automated system, no hold queue, no callback tomorrow. We ask about your lock type, door material, and what you need done, then quote your price before we dispatch. That price does not change when we arrive.
- 2
Scheduled arrival with ID verification. Your technician arrives in a marked Strongbox vehicle, in uniform, and presents identification at your door. We have background-checked every employee who enters Illinois homes, and we expect you to verify who we are. This is standard procedure, not an exception.
- 3
On-site assessment and confirmation. Before touching any tools, we confirm the scope of work matches what we quoted and inspect for any structural issues - warped doors, misaligned frames, or damaged strike plates - that would affect the installation. If we find something unexpected, we discuss it with you before proceeding. No surprises.
- 4
Precision installation or rekeying. For installations, we use door jigs and mortising templates to ensure clean, accurate fits without splintering wood or damaging finishes. For rekeys, we disassemble the cylinder on a clean work surface, replace the pin stack to your new key code, and test every key multiple times before reassembly.
- 5
Final testing, cleanup, and written guarantee. We operate the lock from both sides, check latch and deadbolt alignment, and verify all keys work smoothly. We leave your work area clean, provide your written 90-Day Done Right Promise, and make sure you know how to reach us if anything needs adjustment. If it is not right, we come back. No paperwork, no arguing.
How Much Does Lock Installation & Rekey Cost in Illinois?
A typical lock rekey in Illinois runs $89-$125 per cylinder, depending on the lock type and whether we are rekeying multiple locks to match a single key. Standard lock installation - removing old hardware and installing a new deadbolt or entry set - typically ranges from $140-$240 for residential grade hardware. Smart lock installation, which requires Wi-Fi configuration and app setup, generally falls between $180-$340 including the labor and any necessary door prep.
Several factors affect where your job falls in these ranges. High-security locks like Mul-T-Lock or Abloy require specialized pinning kits and training, which adds to labor cost but provides significantly greater protection. Doors that need structural repair - new strike plates mortised into steel frames, or wood filler and re-drilling for misaligned holes - take additional time. And jobs outside standard business hours carry a modest trip charge, though we still quote the total upfront.
To avoid overpaying, get your price in writing or by clear verbal quote before anyone starts work. The $19 service-call tactic is designed to get a technician inside your home where pressure tactics take over. At Strongbox, the price we quote is the price you pay. Our free estimate includes a full assessment with no obligation, and we honor our standing offers: $50 off any repair over $250, a free second opinion on any written estimate, our $89 seasonal tune-up, and a permanent 5% discount for seniors and veterans.

Frequently Asked Questions - Lock Installation & Rekey in Illinois
Lock installation removes old hardware and mounts new locks on your doors; rekeying changes the internal pin configuration of an existing lock so old keys no longer work while the hardware stays in place. Rekeying is faster and less expensive when your locks are in good condition but you need to control who has access. We do both, and we will tell you honestly which approach makes sense for your situation.
Most residential rekeys take 15-30 minutes per lock, and a standard lock installation takes 30-45 minutes per door. Smart lock installations or jobs requiring door repair may run 60-90 minutes.
