Commercial Locksmith in Northwest Indiana

Security gaps at a business, whether from staff turnover, outdated hardware, or an office lockout, need to be resolved quickly and correctly. Keys4U works with retail shops, offices, warehouses, and property managers across Lake, Porter, and LaPorte counties. Our technicians are insured, background-checked, and carry a wide selection of commercial-grade hardware in the van, so most jobs are completed in a single visit.

What we handle

  • Master key system design and installation: Create a keying hierarchy that gives each employee access only to what they need.
  • High-security lock upgrades: Install pick-resistant, drill-resistant cylinders for doors that protect sensitive areas or assets.
  • Office and commercial lockouts: Regain entry to your business using non-destructive methods whenever possible to protect the door, frame, and lock hardware.
  • Rekey after staff turnover: Render former-employee keys inoperative across one door or an entire building.
  • Panic bar and exit device service: Inspect, adjust, or replace commercial exit hardware to maintain code compliance.
  • Lock changes for new tenants or ownership: Replace cylinders across the property so previous occupants cannot re-enter.

Planning a commercial rekey or upgrade

Before the visit, it helps to have a list of doors you want on the system and a clear idea of which staff levels need access to which areas. We assess the existing hardware, note any doors that need hardware replacement rather than rekeying, and walk you through the keying plan before any work begins. Pricing is based on the number of cylinders and any new hardware required.

Frequently asked questions

How does a master key system work? +

A master key system pins each lock so that individual keys open only specific doors while a master key opens all of them. We design the hierarchy based on your floor plan and staffing structure.

Should I rekey or replace locks when an employee leaves? +

Rekeying is usually the faster and less expensive option if the hardware is in good condition. We can rekey all affected cylinders in one visit so former employee keys stop working immediately.

Do you work outside normal business hours for commercial clients? +

We are available daily from 7:00 AM to 10:00 PM, including weekends. For planned work like a full building rekey, scheduling during off-hours minimizes disruption to staff.
