Break-In Prevention: 12 Locksmith Tips for Centurion & Pretoria Homes

Most break-ins aren't the work of a determined, skilled criminal defeating a top-of-the-range lock — they're opportunistic, targeting the easiest entry point available. That's actually good news: it means a relatively small number of practical upgrades and habits can meaningfully reduce your risk. Here are twelve, ranked roughly from quickest wins to bigger projects, drawn from what our technicians see repeatedly across homes in Pretoria and Centurion.

1. Upgrade to a Graded Deadbolt

Your front and back doors are the most common entry points, and the deadbolt is doing most of the work. A higher-grade deadbolt with a solid, complex locking mechanism resists forced attacks far longer than a basic builder-grade lock. If you're not sure what grade your current locks are, a residential locksmith can assess and recommend an upgrade in a single visit. As a rule of thumb, if your current deadbolt came standard with a builder-grade door installed more than a decade ago, it's almost certainly due for an upgrade.

2. Reinforce Your Strike Plate

A surprising number of break-ins succeed not by defeating the lock itself, but by kicking the door hard enough to tear the strike plate out of a thin door frame. A reinforced strike plate with longer screws anchored into the structural frame — not just the door trim — dramatically increases resistance to this kind of forced entry, often for a very small cost. It's one of the cheapest upgrades on this entire list relative to the security it buys you.

3. Secure Sliding Doors Properly

Sliding doors are frequently the weakest point in an otherwise well-secured home, since their latches are often less robust than a standard door lock. Adding a secondary slide-locking bar, security pins, or an upgraded latch prevents the door from being lifted off its track or forced open, even if the primary lock is compromised. Don't overlook sliding doors leading onto a patio or pool area simply because they feel less exposed than a street-facing entrance — from a security standpoint, an unlocked side door is just as inviting as an unlocked front door.

4. Fit Proper Security Gates

Fully framed security gates on external doors are significantly harder to defeat than semi-framed designs, since they distribute force across the whole frame rather than a single weak point. Make sure the locking mechanism engages in more than one place along the gate for the best resistance. Older security gates installed decades ago are also worth a second look — many were fitted with locks that are now considered relatively easy to bypass, even if the gate frame itself still looks sturdy.

5. Improve Exterior Lighting

Poorly lit entry points, side gates, and driveways give an opportunistic intruder time and cover to work unnoticed. Motion-activated lighting at every entry point — front door, back door, side gate, garage — removes that cover cheaply and effectively, and is one of the best return-on-investment upgrades available. Solar-powered motion lights are a practical option for side passages or boundary walls that aren't already wired for electricity.

6. Reduce Hiding Spots Near Entry Points

Overgrown shrubs, tall walls next to windows, and cluttered side passages all give an intruder somewhere to work unseen. Trim back vegetation near doors and windows, and keep sightlines from the street or neighbouring properties as open as reasonably possible.

7. Don't Overlook Window Locks

Windows are often left unlocked far more casually than doors, especially on upper floors that feel "safe." Make sure every window that can be reached from a wall, roof, or ladder has a functioning lock, not just the ground-floor ones.

8. Stop Hiding Spare Keys Outside

Under the mat, in a flowerpot, above the door frame — these hiding spots are well known to anyone casing a property, not just to you. Leave a spare key with a trusted neighbour or family member instead, or install a proper keypad lock through a reliable locksmith if convenience is the concern.

9. Rekey After Moving In

If you've recently bought or rented your home, you don't actually know how many keys exist for it, or who holds them. Rekeying every external lock in your first week is one of the highest-value, lowest-cost security steps available — see our full rekey vs replace guide for how to approach it.

10. Pair Locks with Your Alarm System

Good locks slow an intruder down; a monitored alarm system ensures that delay actually results in a response. The two work best together rather than as alternatives to one another — a lock buys time, an alarm makes sure that time matters.

11. Build a Simple Daily Security Routine

Consistency matters more than any single upgrade. A short nightly routine — checking all doors and windows are locked, gates are closed, and outdoor lights are on — closes far more gaps than people expect, since most break-ins exploit a door or window that was simply left unlocked rather than defeating a lock at all.

12. Know Your Neighbours

A street where neighbours notice unfamiliar vehicles, unusual activity, or an open gate is a meaningfully harder target than one where everyone keeps entirely to themselves. This costs nothing and is consistently one of the most effective deterrents in residential areas across Pretoria and Centurion. A quick WhatsApp group with immediate neighbours, used to flag anything unusual, is a low-effort way to formalise this.

Extra Precautions When You're Away From Home

An empty house over a long weekend or holiday period is a different risk profile to your everyday routine, and worth a few extra steps:

• Avoid broadcasting your absence on social media in real time — save the holiday photos for when you're back.
• Ask a trusted neighbour to collect post and move a bin occasionally, so the property doesn't visibly sit untouched.
• Use timer switches on a light or two rather than leaving everything dark for days at a time.
• Double-check every entry point before you leave — this is the moment a rushed departure most often results in a window or side gate left unlocked.
• Let your alarm company and a trusted neighbour know your travel dates, so an alarm trigger gets an appropriate response rather than being dismissed as a false alarm.

Combined with the upgrades above, a few minutes of planning before you leave closes most of the gaps that opportunistic break-ins tend to exploit while a home sits empty.

Frequently Asked Questions

What's the single most effective upgrade against break-ins?

There's no single answer, but a graded deadbolt combined with a reinforced strike plate addresses the most common point of forced entry for the lowest cost.

Do security gates actually help if I already have good door locks?

Yes — gates add a second layer an intruder has to defeat, and buy meaningful extra time even if a lock is eventually compromised.

Should I upgrade all my locks at once, or gradually?

Prioritise your most exposed entry points first — typically the front door, back door, and any sliding doors — then work through the rest as budget allows.

How do I know if my current security gate is actually still effective?

Test the lock and hinges for wear, check for any signs of previous tampering, and if it's more than 15 years old, it's worth having a locksmith assess whether the locking mechanism still meets current standards.
