Yes, this padlock is available with several keying options to suit your requirements:

  • Keyed Alike: Multiple locks can be manufactured to operate using the same key for convenience.
  • Masterkeyed: A system where individual keys open specific locks, but one master key can open all of them.
  • Backward Compatibility: It can even be keyed alike to older Squire Stronglock models in the 35, 37, or 39 series.

The Squire Stronglock Plus Key is a dedicated accessory designed for the Stronglock Plus series of padlocks. It functions as a supplementary or replacement key, ensuring that security systems remain accessible to all authorised personnel. Each key is precision-engineered to match the internal pin configurations of the padlock, maintaining the high security standards of the Stronglock Plus range.

Typically used in commercial and industrial environments, these keys are ideal for situations where the standard number of keys provided with a padlock is insufficient. They are frequently specified for facility management where keyed-alike systems are implemented, allowing one key to operate multiple locks across a site.

These keys are intended for selection alongside the purchase of new padlocks to ensure a perfect mechanical match. By ordering additional keys at the point of manufacture, users can ensure consistent operation and reduce wear on the internal locking mechanism.

The Squire Stronglock Plus Masterkey padlock is a high-security locking solution specifically engineered for use within master keyed systems. This functional design allows for a hierarchy of access, where individual locks are operated by their own specific keys while a single master key provides overriding access to every lock within the suite.

Constructed with a robust laminated steel body, this padlock is built to endure demanding environments. The hardened steel shackle provides a significant deterrent against physical attacks, particularly cutting and sawing. Internally, the six-pin cylinder mechanism ensures a high level of security against specialist manipulation techniques such as picking.

Typical applications include:

  • Securing perimeter fencing and gates on commercial or industrial sites
  • Managing multi-user access to site storage and tool containers
  • Integration into facility management security protocols for schools or warehouses
  • Providing secure access to communal areas in residential developments

These padlocks are ideal for both new security installations and the expansion of existing Squire Stronglock Plus suites. Their technical design focuses on long-term durability and reliable performance, ensuring consistent operation even when used in external applications where weather resistance is required.
