What Does Rekeying a Lock Mean?

Rekeying involves changing the internal components (pins or wafers) of a lock so that it works with a new key while disabling the old one. This solution enhances security without the need for a complete lock replacement.

Why Rekey a Lock Without the Original Key?

  • Lost or Stolen Key: Prevent unauthorized access by rendering the old key ineffective.
  • New Property: Change the locks immediately after acquiring a new home or office.
  • Broken Key: If the original key is broken or damaged beyond repair, rekeying is essential.
