Replacement security screen door locks, hinged and sliding

A security door lock usually needs replacing for one of three reasons: the key won't turn, the latch won't catch, or you've moved house and want new keys. Start by working out whether you need a complete kit, the lock body only, or just the snib set. The Security Screen Door Lock Buying Guide walks you through it in six questions.

• Hinged or sliding: these use different lock bodies, so check the door type first.
• Cylinder: choose double-wafer, 4-pin C4 or 5-pin commercial.
• Compatibility: our locks directly replace Whitco® (Tasman MK1, Leichhardt™), Lockwood® (8654 series), Doric™, Austral™, Brava™, Magic™, Yale™ and Schlage™.
• Standards and finish: compliant with AS 5039, AS 5040 and AS 5041, in six COLORBOND®-matched colours.

Only need new keys? Replace the lock cylinder. Multi-pack cylinders come keyed alike, so one key opens every door. For strikers, lock guards, hinges and closers, see security door hardware.

Security door lock FAQs

Can I just replace the barrel instead of the whole lock?
Yes, if the lock body still works. Swapping the cylinder gives you new keys and costs less than a full lock.

Will this fit my Whitco® or Lockwood® door?
Our locks are direct replacements for the models listed above. Match the hinged or sliding type and the lock body style to your old lock.

What does keyed alike mean?
Every lock or cylinder in the pack opens with the same key.
