Commercial Rekey & Master Key Systems


Managing keys for a business can be a nightmare. We design and implement Master Key Systems. This allows you (the owner) to have one Grand Master key that opens every door, while your managers have keys that open only their departments, and general staff have keys that open only the front door. This granular control improves security and internal accountability.

Access Control & Keyless Entry


Metal keys are becoming obsolete in modern business. We install electronic access control systems, including keypad locks, card readers, and mag-locks. These systems allow you to add or delete user credentials instantly—no need to call a locksmith to rekey the building every time an employee leaves.

Panic Bars and Exit Devices


Safety compliance is just as important as security. We install and repair push bars (panic bars) and door closers that meet local fire codes and ADA requirements. A malfunctioning door closer can slam on a customer or leave a door unlocked; we adjust and replace the hydraulic arms to ensure smooth, safe operation.

Frequently Asked Questions


  • Can you rekey a file cabinet? Yes. We can generate keys for lost file cabinet locks or replace the cam locks entirely to secure sensitive documents.
  • What is a "Do Not Duplicate" key? We can install "Restricted Keyways." These keys cannot be copied at a hardware store; they can only be duplicated by the authorized locksmith with a letter of authorization from the business owner.
  • My storefront door slams shut too hard. Can you fix it? Yes. This is usually a hydraulic fluid leak or adjustment issue in the door closer. We can adjust the sweep and latch speeds or replace the unit if it has failed.
  • Do you offer billing accounts for businesses? Yes, we work with property managers and business owners to set up commercial accounts for ongoing maintenance and emergency services.
  • How fast can you respond to a break-in? We treat break-ins as emergencies. We can arrive quickly to secure the building, repair the door frame, and replace the compromised locks to get you back in business.
