Break-In Prevention: What Adelaide Burglars Actually Look For

Adelaide burglars overwhelmingly target the easiest house on the street, not the most valuable one. They are looking for an unlocked door or window, a side or rear entry hidden from the street, and no sign that anyone is home, and they usually decide in under a minute whether a property is worth the risk. Break-in prevention is less about installing one expensive device and more about removing every one of those easy signals at once.

What burglars actually look for

Police data and the pattern the mobile locksmiths in our network see after the fact both point the same way: most Adelaide break-ins are opportunistic, not planned. A person walking past tries a few handles and windows on the way home, and the ones that give way are the ones that get entered. The jobs we get called to after a break-in almost always share the same story: a rear sliding door left on the latch, a side gate that was never locked, or a single-cylinder deadbolt that popped with a screwdriver in the door frame itself rather than the lock failing.

• Speed: anything that takes more than a minute or two to get through gets skipped, because the risk of being seen goes up fast.
• Cover: side and rear entries hidden by fences, garages or overgrown hedges are targeted far more than an exposed front door.
• Signs nobody is home: no car in the driveway, curtains shut in daylight, mail piling up, no lights at night.
• An easy exit: a house that lets them get out fast with the goods is preferred over one with a single choke-point exit.

The unlocked door or window problem

A large share of Adelaide break-ins involve no forced entry at all. The offender simply pushes on a door or window that was left unlocked, often a laundry window, a garage internal door, or a sliding door that was closed but not latched. This is the cheapest fix on this whole list and the one most often skipped, because it costs nothing and feels too simple to matter. Walk your property at night, from the street, and check every point of entry the way an opportunist would: not just the front door, but the side gate, the garage roller door's manual override, and any window low enough to reach from the ground.

If you rent, have had tradespeople through recently, or simply cannot remember how many spare keys exist for the property, read our guide on when to replace locks before assuming the locks themselves are the weak point. Sometimes the lock is fine and the problem is who still has a working key.

Deterrence that actually works

Most home security spending in Adelaide goes on things that look good on a brochure but do little against an opportunistic offender casing a street in daylight. The measures that consistently change an offender's decision are cheaper and less flashy:

• Visible deadlocks: a deadbolt an offender can see through the glass or against the frame signals a harder job before they even try the handle.
• Sensor lighting at every entry: side and rear entries in particular, since darkness is what cover relies on.
• Clear sightlines: trim hedges and fencing near doors and windows so a neighbour or passer-by can actually see someone loitering.
• Key control: know exactly how many keys exist and who holds them, particularly after a rental change, break-up, or tradesperson job.
• Occupied signals: a car in the driveway, a radio on, or a neighbour collecting mail during a trip away.

Your front door is usually the least of the problem, since it is the most visible and the most likely to have a solid lock already. Our guide to securing your front door covers the specific hardware upgrades worth making there, but the bigger wins on most Adelaide properties sit at the side and rear.

Secure the rear and side entries first

If you only have time or budget to fix one thing, fix the entry the street cannot see. In the jobs the locksmiths we connect with attend after a break-in, the point of entry is a rear sliding door, a side gate leading to an unlocked back door, or a garage's internal access door far more often than the actual front door. A sliding door benefits from a secondary track lock or a simple dowel in the frame, on top of whatever lock it already has. Side gates should lock, not just latch, and garage internal doors deserve the same standard of lock as the front of the house, not whatever builder- grade hardware was fitted at construction.

A licensed locksmith can assess the whole property in one visit and tell you which entries are the actual weak points, rather than guessing. Our residential locksmith page covers what a full home security check typically involves and how the connect-and-quote process works.

Getting a proper assessment done

A DIY walk-around catches the obvious gaps, but a locksmith who does this for a living will spot things you would not: a deadbolt fitted into a soft timber frame that would fail under a single kick, a window lock that looks secure but is decades old and brittle, or a lock that is technically deadlocked but was never rekeyed after you moved in. None of this needs to cost much to fix once it is identified, and most of it is a one-visit job.
