Secure doors mean peace of mind. Whether it’s your family home, a rental property, or your business, a properly installed and reinforced lock keeps everything and everyone safe. ATC Property Services helps Southland property owners fix, upgrade, and protect their entry doors with reliable lock repair, deadbolt installation, and reinforcement services.

Door Lock Repair, Reinforcement & Deadbolt Installation in the Chicago Southland

When a lock sticks, a latch won’t catch, or a door doesn’t close right, it’s more than a nuisance—it’s a security risk. Our licensed technicians diagnose and repair all types of door-lock issues for residential and light-commercial properties throughout the Chicago Southland. From simple latch adjustments to full lock and deadbolt replacements, we make sure your door hardware works exactly as it should.

Professional Door Lock Repair for Homes and Businesses

Over time, locks wear out, keys bend, and hardware shifts.  ATC Property Services provides on-site repairs for:

  • Misaligned latch or strike plates

  • Locks that don’t turn or fully engage

  • Loose handles and hardware

  • Broken key cylinders or interior latches

  • Damaged door frames after a forced entry

We service major brands such as Schlage, Kwikset, Yale, and Baldwin, and we can match your existing finish so repairs blend seamlessly with your door’s style.

Door Reinforcement & Security Upgrades

A strong lock is only as good as the door and frame that hold it. We reinforce weak frames with heavy-duty strike plates, longer screws, and metal wrap plates that protect against kick-ins and forced entry. Our team can also upgrade hinges, install door armor kits, and ensure the lock bolts extend deep into solid wood or metal framing.

Ideal for:

  • Homes with aged wood door frames

  • Rental properties requiring extra tenant security

  • Storefronts and small business entries

  • Multi-unit buildings needing consistent security standards

Deadbolt Installation & Replacement

Adding a deadbolt is one of the simplest ways to improve door security. We install single-cylinder, double-cylinder, and keyless smart deadbolts on wood, steel, and fiberglass doors.

Popular upgrades include:

  • Smart deadbolts with keypads or Wi-Fi access

  • Grade 1 ANSI-rated hardware for commercial use

  • Decorative finishes to match existing door hardware

If you’re replacing a builder-grade lock, we’ll help you choose a durable, tamper-resistant option that balances security with style.

Emergency Lock & Door Service

Lockouts and damaged locks don’t wait for business hours. We offer same-day and after-hours repair appointments across the Southland area. If a lock is broken after a break-in or the door won’t close securely, call our team and we’ll get a technician on site quickly.
