When ordering multiple Keyed Alike locks, only 1 set of keys are provided as all additional locks are made to work from that key.

If ordering 4 or more keyed alike locks you can have them set up as different groups. If Required: Let us know the details in the "Specific Key Requirements" field above.

Each group of locks will then receive keys.

tick Latch & Deadbolt

The Lockmaster Keywind Latch & Deadbolt Single Spindle Gearbox is a precision-engineered replacement part designed for high-security door systems. Featuring a 45mm backset and 92mm centres, this gearbox serves as an ideal, cost-effective repair solution for common lock failures where the full locking strip is still in working condition.

This unit utilizes a keywind mechanism (Locking Method C). Operation is secure and intuitive: two full turns of the key are required to engage the deadbolt, and two full turns to unlock it. An additional turn of the key effectively withdraws the latch for entry. The single spindle design ensures compatibility with a wide range of standard handle sets.

Key specifications and features include:

  • Reversible Handing: The latch can be easily reversed to suit both left and right-handed applications by simply removing a screw.
  • Euro Profile Case: Built to accommodate standard Euro profile lock cylinders.
  • Durable Latch & Deadbolt: Provides dual-action locking for maximum protection.
  • Universal Fit: Specifically designed to match the footprint of existing Lockmaster gearboxes for a seamless replacement process.
