5 Common Commercial Lock Problems in Boston (And How to Prevent Them)

From jammed locks to worn-out cylinders, Boston businesses face unique security challenges. Here’s how to stay ahead.

Boston is known for its historic architecture, dense foot traffic, and vibrant business districts. But these same traits create unique security challenges for commercial properties. At Astro Locks, we’ve worked with countless businesses across neighborhoods like Back Bay, the South End, and Dorchester. Here are the five most common commercial lock problems we encounter in Boston—and how to avoid them.

1. Worn-Out or Corroded Locks
Boston weather can be tough on hardware. From humid summers to icy winters, locks exposed to the elements—especially those on storefronts and back exits—tend to wear out quickly. Salt in the air (especially in waterfront areas like Seaport and East Boston) accelerates corrosion.

What to Do:
Inspect exterior locks every 6 months. Choose weather-resistant commercial locks (such as stainless steel or brass). At Astro Locks, we recommend brands like Mul-T-Lock and Schlage for their durability.

2. Too Many Keys in Circulation
High employee turnover or shared access among staff can create a key management nightmare. Over time, you may lose track of who has access, leaving your business vulnerable.

What to Do:
Rekey locks after major staffing changes. Better yet, switch to a restricted keyway system that prevents unauthorized duplication. For higher-security needs, upgrade to keyless entry or access control.

3. Misaligned Doors and Lock Hardware
Older buildings in Boston settle and shift over time. This can misalign doors and frames, making locks hard to turn—or completely ineffective.

What to Do:
Have your commercial doors checked annually for alignment. Astro Locks can adjust strike plates, replace hinges, or recommend reinforced doors that resist warping and sagging.

4. Lockouts at the Worst Time
Lost keys, broken locks, or jammed deadbolts can halt business operations. We've rescued restaurants before dinner service and retail shops just before weekend rushes.

What to Do:
Establish a relationship with a reliable local locksmith. Astro Locks offers fast commercial lockout service throughout Boston. We also recommend installing lockboxes for property managers or emergency backup systems for critical doors.

5. Outdated or Insecure Lock Systems
Still using standard knob locks? These are easy targets for break-ins. Many older buildings are overdue for a security upgrade.

What to Do:
Upgrade to high-security commercial locks, such as Medeco or Mul-T-Lock. We also install panic bars, commercial deadbolts, and ADA-compliant hardware for businesses that want to stay secure—and up to code.

Bonus Tip: Security Audits Matter
A proactive security assessment can identify issues before they turn into emergencies. At Astro Locks, we offer free walk-throughs for commercial properties in Boston and surrounding neighborhoods.
