Changing Business Locks After an Employee Leaves: A Same-Day Checklist

Managing physical security during a termination requires structured timing. Moving step-by-step helps ensure no perimeter door, server room, or filing system is overlooked.

• Phase 1: Pre-Termination (T-minus 24 to 2 Hours)
  Review your facility map and list all locks the departing employee had access to, including exterior doors, executive offices, and inventory rooms. Contact a professional commercial locksmith service to schedule an appointment for a one-hour window immediately following the planned termination meeting.
• Phase 2: The Exit Interview (T-0)
  Request the immediate return of all physical keys, fobs, and access cards. Document the key codes and badge numbers. Ask the employee directly if any duplicates were made, and note their response for legal documentation.
• Phase 3: Immediate Lock Action (T-plus 1 to 2 Hours)
  Once the employee has left the premises, execute commercial rekeying of the physical lock cylinders. Manually update exterior keypads and alarm PINs immediately—never reuse old master codes or simple sequence combinations.
• Phase 4: Post-Termination Ledger (Within 24 Hours)
  Distribute the newly rekeyed physical keys to remaining authorized staff. Record every signature in a centralized key-control ledger and audit your security cameras to ensure all primary entry and exit points are fully operational.

A common response from frustrated business owners is to deduct the cost of rekeying from the departing employee’s final paycheck if they fail to return their keys. However, doing so can lead to severe legal and financial penalties.

Under the federal Fair Labor Standards Act (FLSA), employers cannot deduct the cost of lost tools, keys, or lock changes if the deduction drops the employee’s final wages below the federal minimum wage ($7.25 per hour) or cuts into earned overtime pay.

State laws are often even stricter. For example, California Labor Code Section 221 makes it completely illegal to deduct business losses or lock-changing fees from a final check, regardless of how much the employee earns. Similar tight restrictions apply in states like New York and Minnesota.

To protect your business, use a signed “Key and Security Asset Agreement” during onboarding to establish clear expectations. If keys are not returned, seek remedy through direct invoicing or civil court rather than risking a wage-and-hour lawsuit.
