  • Each lock includes a unique set of keys.

What is Keyed Alike?

The possibilities are endless - from having one key per family member unlocking the front door, kitchen and patio doors, right up to large-scale company storage keying options.

  • Each key can open multiple locks - the same key could unlock your house and office.
  • Locks need to be the same brand and number of levers.
  • Keyed Alike locks include one set of keys regardless of how many locks are purchased.
  • Made to order so NOT covered by our returns policy.
