Triple locks

A triple lock is one lock with three bolts. Turn the key or the snib and a rod inside the door throws a bolt into the jamb at the top, the middle and the bottom. A single lock holds the door at one point, so it can be levered at the top or bottom; three points can't be. Security doors are tested with triple locks, which is why the standard calls for them. Ours are Austral Lock as standard, with Lockwood as the premium option.

  • Standard on our security doors
  • keyed alike with your other Factory Fit doors on request
  • snib inside for quick locking without a key

Digital locks

A keypad or fob on the security door, so children, cleaners and tradespeople can get in without a spare key in circulation, and so you can change the code when someone moves out. They run on batteries with a warning before they go flat, and they still have a key override. Worth it if you regularly leave a key out; not worth it on a door that is rarely used.

Handles, hinges and wheels

  • Handles

    Matched to the lock and colour-matched to the frame where the range allows.

  • Hinges

    Hinged doors get heavy-duty hinges, colour-matched; fire escape windows use outward-opening hinges with an inside release.

  • Wheels

    Sliding doors run on adjustable wheels; if a door starts to drag years later, wheels are usually the fix, not the door.

Which upgrades are worth it

  • Turning the key in a triple lock on a diamond grille door, with each bolt shown close up

    Triple lock

    Optional

    Already on our security doors. If you want one on a fly screen door, you probably need a security door; talk to us.

  • Entering a code on a keypad lock on a diamond grille door

    Digital lock

    Optional

    Worth it: families, short-term rentals, anyone who leaves a key out. Not worth it: a laundry door nobody uses.

  • One key opening several door locks around a home, shown in close-ups

    Keyed alike

    Optional

    Worth it: three or more doors. One key for all of them.

    Worth it: any door a dog leans on. Stops the scratching before it starts.

Looking after your locks

Silicone spray every six months, every three near the coast or industry.

  1. Open the door

  2. Unlock with the snib so the top and bottom bolts retract

  3. Spray silicone into each lock point

  4. Turn the handle and spray the centre lock

  5. Work the snib back and forth

    Use dry silicone, not oil

Locks and hardware questions

What is a triple lock?

A three-point lock: one key or snib throws bolts into the door jamb at the top, middle and bottom through a rod inside the door. It stops a door being levered open at the top or bottom, which a single centre lock can't. It's fitted as standard on our security doors.

Can I have a digital lock on a security screen door?

Yes, as an upgrade on. Keypad or fob entry, with a key override and low-battery warning. Useful for children and tradespeople, and you can change the code at any time. Ask at the measure and we'll show you the unit.

Can all my doors use the same key?

Usually, yes, if you ask at the quote stage; locks are keyed alike before the doors are made. Rekeying existing doors later is possible through a locksmith.

Are triple locks required on a security door?

Security doors are tested to the Australian standard with a triple lock fitted, so a single lock would drop the door below its tested rating. If you're buying a security door, a triple lock isn't an upgrade, it's part of the door.

My lock is stiff. What do I do?

Spray dry silicone into the lock points with the snib unlocked, then work the snib and handle a few times. Don't use oil; it attracts grit. If it's still stiff, or the key turns but the bolts don't move, call us before forcing it; a worn lock is a quick replacement.

Do the locks have their own warranty?

Locks and hardware carry their own period, listed on the warranty page: 12 months on Xceed. Keep the lock clean and lubricated; a seized lock from neglect isn't a warranty fault.
