Our Lock Installation & Rekey Services in Addison
Smart Lock Installation
Smart lock installation in Addison’s older homes requires more than screwing a new device onto old hardware. The 1960s ranches near Army Trail Road often have steel door frames that shifted decades ago, and a smart lock’s motorized bolt needs precise alignment to function reliably. We install Yale and Schlage smart locks with proper strike-plate reinforcement, and we always check whether your Wi-Fi signal reaches the door. A typical smart lock installation in Addison runs $220-$420, including rekeying any matching deadbolts to your existing house key.
Keyless Entry
Keyless entry systems work well for Addison families who want to stop hiding spare keys under the mat. For the 1980s townhomes near Addison’s Community Park, we install keypad deadbolts that don’t require drilling new holes in the door. Most of these units already have standard 2-1/8″ bore holes, so the swap is clean. We program up to 25 user codes and show you how to add or delete them. Keyless entry installation in Addison typically costs $180-$340.
Keypad Lock
Keypad locks suit rental properties and multi-generational households in Addison’s condo subdivisions. We install commercial-grade keypad locks from Schlage and Baldwin that withstand DuPage County’s temperature swings better than budget hardware-store models. The rubberized keypads on cheap units crack after two winters. We don’t install those. A residential keypad lock with professional installation runs $200-$380 in Addison.
Biometric Lock
Biometric locks - fingerprint readers - are increasingly popular for Addison homeowners who want keyless convenience without remembering codes. These units demand more precise door prep than standard deadbolts, and Addison’s older steel frames often need shim adjustment before the bolt throws smoothly. We install fingerprint locks that store 50+ prints and include mechanical key override. Expect $280-$520 for biometric lock installation in Addison, depending on door condition and whether we need to rebuild the strike pocket.
Electronic Lock
Electronic locks cover the full spectrum: keypad, card reader, Bluetooth, and hardwired access control. For Addison’s commercial properties along Fullerton Avenue, we install electronic locks tied to master-key systems, allowing property managers to rekey electronically instead of replacing cylinders at every turnover. We also retrofit older commercial doors with electronic strikes that work with existing panic hardware. Commercial electronic lock work in Addison starts around $350 per door and scales with system complexity.

Trusted Brands We Service in Addison
We stock and install Medeco, Yale, Baldwin, and Mul-T-Lock hardware from our Addison-area inventory. For the commercial corridors along Fullerton Avenue and Lake Street, we keep Schlage and Falcon commercial keyway blanks on hand specifically for the master-key re-cores that follow tenant turnover. Most residential jobs in Addison’s 60101 zip code draw from our standard deadbolt and smart lock stock, meaning same-day completion without waiting for parts. When a homeowner in an older ranch near Centennial Park needs a Medeco high-security cylinder to match an existing system, we typically have the pinning kit ready.
Common Lock Installation & Rekey Problems We See in Addison Homes
- Frozen pin-tumbler cylinders every January and February. DuPage County’s freeze-thaw cycling pushes moisture into older Kwikset and Schlage cylinders, where it expands and seizes the pins. We replace these with weather-resistant cylinders or upgrade to electronic locks that eliminate the mechanical failure point entirely.
- Misaligned deadbolt throws in aging steel door frames. The ranch homes built during Addison’s 1950s-70s expansion carry steel frames that shift seasonally. The deadbolt scrapes, binds, or fails to extend fully into the strike plate. We don’t just file the strike - we diagnose whether the frame has settled and install an adjustable reinforced strike that compensates for future movement.
- Legacy commercial master-key systems with broken hierarchies. Industrial parks along Fullerton Avenue have been partially rekeyed by multiple vendors over decades, creating situations where a sub-master key opens doors it shouldn’t, or a tenant key works in a common-area lock. We audit the entire key bitting array and rebuild the system to spec.
- Worn original hardware in 1960s ranches that can’t be rekeyed again. Some Kwikset deadbolts have been rekeyed four or five times since installation, and the plug walls are too thin to accept new pins. We replace with new Schlage B60N grade-2 deadbolts, rekeyed to match your house key, and reinforce the strike plate while we’re at it.

FAQs - Lock Installation & Rekey in Addison
Yes, we replace frozen original deadbolts with smart locks in Addison’s older ranches several times each winter. The sticking is caused by DuPage County’s freeze-thaw cycles forcing moisture into the cylinder; we remove the failed hardware, reinforce the steel frame strike plate to correct seasonal misalignment, and install a Schlage or Yale smart lock that eliminates the mechanical pin-tumbler entirely. Most of these jobs run $220-$340 and take about 90 minutes. Call (844) 321-2640 for a free estimate - we can usually schedule within 24 hours.
We can rekey 20 commercial roll-up door cores in one business day, and we stock Schlage and Falcon keyway blanks specifically for Fullerton Avenue corridor properties. Our crew arrives with a mobile pinning kit and pre-cut keys, working bay by bay to minimize disruption to remaining tenants. A 20-unit re-core in Addison typically runs $1,200-$1,800 depending on whether we’re rebuilding the master-key hierarchy or simply changing to a new sub-master. Call (844) 321-2640 to schedule - we understand lease-turnover urgency and prioritize these jobs.
Sometimes, but often replacement is the better value for Addison’s 1970s split-levels with original steel doors. The retracting failure usually means the bolt is binding against a misaligned strike plate or the internal cam is worn from decades of forcing the key. We inspect on arrival; if the deadbolt body is intact, we may rebuild the strike pocket and lubricate the mechanism for $85-$140. If the internal parts are worn or the cylinder has been previously rekeyed too many times, we recommend a new Schlage B60N deadbolt with reinforced strike installation for $180-$240. We quote both options on the phone so you can decide before we arrive.
Yes, 1980s townhomes in Addison are excellent candidates for keyless entry retrofits because they typically have standard 2-1/8″ door bores and fiberglass or steel doors that accept modern hardware without modification. We install Schlage and Baldwin keypad deadbolts that fit the existing prep, program your codes on-site, and rekey any matching deadbolts to your current house key. Installation runs $180-$340 and takes about an hour. Call (844) 321-2640 to book - estimates are free.
Yes, we specialize in unifying mixed-vendor commercial lock systems into coherent master-key hierarchies for Addison’s Lake Street and Fullerton Avenue industrial properties. We audit every cylinder, identify compatible keyways, and replace non-compatible hardware where necessary. The goal is one master key for property management, sub-masters for tenant blocks, and individual keys that don’t cross over. A full audit and rebuild for a 15-25 bay warehouse typically runs $1,500-$2,800. We quote flat after a walk-through - call (844) 321-2640 to schedule.
