How to Burglar-Proof Your Brisbane Home: A Locksmith's Checklist

You lock the front door every night, so your home's secure, right? Maybe. As locksmiths, we get called to Brisbane homes after a break-in far too often, and the same weak points come up again and again. The frustrating part is that almost all of them are cheap and simple to fix before anything happens, not after.
This is the checklist we'd run through if we walked around your place with you. It's not about turning your home into a fortress; it's about closing the easy gaps that opportunistic intruders look for, working from your doors out to your windows, your yard and your lighting. Go through it room by room and you'll quickly see where your weak spots are.
Where do Brisbane homes actually get broken into?
Most break-ins aren't dramatic. Intruders are usually opportunists looking for the quickest way in with the least attention, and they head straight for the parts of a house that can't be seen from the street. In Brisbane that typically means:
- Rear and side doors screened by fences, carports or the neighbour's hedge.
- Sliding glass doors onto back decks and patios.
- Unlocked or poorly latched windows, especially louvres and older aluminium sliders.
- The internal garage door, once someone's into the garage.
- Gates and side access left unlocked, giving cover to work unseen.
Notice the theme: it's rarely the reinforced front door that lets people down, it's everything around the back that nobody thinks about. That's where this checklist spends most of its time.
Is your front door as strong as you think?
Your front door sets the standard, so start here. Three things decide how much it can take: the lock, the strike plate, and the door and frame themselves.
Do you have a real deadbolt, and is the strike plate up to it?
A spring latch (the angled one that clicks shut on its own) can be slipped or forced in seconds. A deadbolt is a solid rectangular bolt that throws deep into the frame and won't retract without the key or thumbturn, and it's the single most important upgrade on any entry door. But a deadbolt is only as strong as what it throws into. The weak link is almost always the strike plate: the metal plate on the frame, held by two short screws that bite into nothing more than the thin doorstop trim. Under a hard kick, those screws tear straight out and the door swings open with the lock still perfectly intact.
The fix is cheap and makes a genuine difference: a heavy-duty strike plate fixed with long screws that reach past the trim and bite into the structural stud behind the frame. It's one of the highest-value security jobs a locksmith does, and it's completely invisible once it's in.
Is the door itself solid?
A hollow-core internal-style door on an external opening is a liability, because they're light, cheap and split easily. External doors should be solid timber or a solid-core construction. On glass-panelled or French doors, make sure the glass is toughened and that a broken pane wouldn't simply let a hand reach in to the thumbturn. If it would, a keyed deadbolt on the inside removes that shortcut.
Are your sliding doors and windows the weak link?
For most Brisbane homes, they are. Aluminium sliding doors are convenient and, unfortunately, easy to defeat if they're not set up properly. The two classic tricks are lifting the panel up and off its track, and levering the flimsy factory latch. Both are simple to shut down:
- Fit an anti-lift device or adjust the anti-jump screws so the panel can't be lifted out of the track.
- Add a dedicated keyed sliding-door lock rather than relying on the standard latch.
- Drop a length of dowel or a security bar into the bottom track as a cheap secondary stop.
- Fit key-lockable latches to windows, particularly ground-floor and deck-accessible ones.
- Replace or secure old louvre windows, where the individual blades can often be slipped out entirely.
Windows deserve the same attention as doors. An intruder would far rather climb through an unlocked window at the back than tackle a locked door out the front, and in our climate windows get left open constantly. Key-lockable locks let you leave a window cracked for airflow while keeping the gap too small to climb through.
Should all your locks open with the same key?
If you're juggling a keyring like a jail warden, there's a better way. Keyed-alike sets let one key operate several locks (front, back, laundry and garage door), which sounds like convenience but is really a security feature. When it's easy to lock every door with the same key, people actually lock every door. A locksmith can set this up by rekeying your existing hardware rather than replacing it, as long as the locks are compatible. If yours are worn, mismatched or of unknown pedigree from a previous owner, our lock rekeying and replacement service can bring everything onto one key and one known standard.
Do lighting and landscaping really matter?
More than most people expect. Intruders rely on cover and darkness, so take both away:
- Fit motion-sensor lights to cover entry points, side access and the back yard.
- Keep hedges and shrubs near doors and windows trimmed low so there's nowhere to work unseen.
- Make sure side gates are lockable and actually kept locked.
- Don't leave ladders, bins or outdoor furniture where they can be used to reach a window or the roof.
- Use timers on a couple of indoor lights when you're away so the house looks lived-in.
None of this is expensive, and together it removes the two things an opportunist needs most: somewhere to hide and the confidence they won't be seen.
Are smart locks worth adding to the mix?
For a lot of Brisbane households, yes, used well. A quality smart lock removes the spare-key-under-the-pot habit, lets you give tradespeople or family a temporary code instead of a cut key, and tells you whether the door actually locked when you left. The important word is quality: a smart lock still needs a solid deadbolt behind it and a properly reinforced frame, or you've just added a keypad to a weak door. If you're weighing it up, our companion guide on whether smart locks are worth it in Brisbane goes through the real pros and cons without the marketing gloss.
What's the locksmith's quick checklist?
Walk your home with this in hand:
- Every external door has a working deadbolt.
- Every strike plate is fixed with long screws into the stud, not short ones into trim.
- Sliding doors are anti-lift protected and have a proper lock or track bar.
- All accessible windows have key-lockable latches.
- Locks are consolidated onto as few keys as sensibly possible.
- Motion lighting covers every entry point.
- Gates lock, and nothing outside can be used as a step-up.
- No spare key is hidden anywhere an intruder would look first.
