  • Restricted Key option – offers added protection against unauthorised key copying
    (the number of key differs increases to 530,000. As protection for you against unauthorised key copying, locksmiths will need you to present the security card supplied with your padlock before they will cut additional keys for you).

  • Protected Key option – offers ultimate protection against unauthorised key copying
    (the number of key differs increases to 530,000. Additional keys can only be cut for you by Squire as the relevant key blanks will not be available to locksmiths. This offers you the highest level of protection against unauthorised key copying.
