How to Rekey Locks When Keys Are Lost in a Commercial Setting

by

In a commercial setting, losing keys can pose serious security risks. Rekeying locks is an effective way to ensure that lost keys no longer grant access. This guide explains how to rekey locks professionally and efficiently.

Understanding Rekeying

Rekeying involves changing the internal pins of a lock so that old keys no longer work, and new keys can operate the lock. It is a cost-effective alternative to replacing entire locksets, especially in a business environment where multiple locks are involved.

Steps to Rekey a Lock in a Commercial Setting

  • Assess the Locks: Identify which locks need rekeying and determine the type of lock (pin tumbler, wafer, etc.).
  • Gather Necessary Tools: You will need rekeying kits, screwdrivers, and possibly a key gauge.
  • Remove the Lock: Detach the lock from the door carefully, following manufacturer instructions.
  • Disassemble the Lock: Open the lock housing to access the pins or wafers.
  • Replace or Reconfigure Pins: Change the pins to match the new key pattern or reconfigure existing pins if possible.
  • Reassemble and Test: Put the lock back together and test with the new key to ensure proper operation.
  • Replace Old Keys: Distribute the new keys to authorized personnel and securely dispose of or store the old keys.

Hiring a Professional Locksmith

While DIY rekeying can be cost-effective, hiring a professional locksmith guarantees the job is done correctly and securely. Professionals have the right tools, experience, and access to high-quality rekeying kits, which reduces the risk of errors.

Additional Security Tips

  • Change locks immediately after losing keys to prevent unauthorized access.
  • Consider upgrading to electronic or smart locks for better control and audit trails.
  • Maintain a record of all rekeying activities and key distributions.
  • Regularly inspect locks and keys for signs of wear or damage.

Rekeying locks after losing keys is a vital security measure for any business. Whether done DIY or by professionals, it helps protect your assets and ensure only authorized personnel have access.
