Locks Perth.


  • Do you need a higher specification lock or padlock that is unavailable from hardware stores?
  • Do you need to upgrade or replace your locks?
  • Do you need a lock repaired or serviced?
  • Do you need to re-key your locks?


Harry Armstrong have been installing and repairing locks for over 121 years. We have a wide range of locks for all situations, particularly higher specification locks that are not available from hardware stores. We use high quality mechanisms and components when we service or repair locks so they last. There are not many types of locks that we have not dealt with in 121 years of service in Perth. Many of our long term clients who depend on us are real estate agencies around Perth and commercial property managers in the Perth CBD.
