If you have bought or moved into a recent build in the Pakenham, Officer, or Cardinia growth corridor, your home is probably less secure than you think. The standard locks installed in builder-grade homes are at the low end of what we recommend.
What builders typically install
A basic mortice or rim lock on the front and back doors, single throw, no anti-pick pins. Standard window latches. A simple keyed lock on the garage door if it has one. These meet building code minimums but they are basic.
Why this matters in growth corridors
New estates are easy targets. Lots of empty homes during the day with both parents working. Streets that look the same so unfamiliar vehicles do not stand out. Fences not yet built. Limited Neighbourhood Watch. Burglary rates in growth corridor suburbs tend to spike in the first few years after development.
What upgrade typically involves
Replace front and back door cylinders with restricted keyway high-security cylinders. Cost about $200 to $350 fitted per door. Add a deadbolt to any door without one. Add window restrictors or keyed window locks to ground floor windows. Cost about $200 to $400 for a typical home.
Total upgrade cost for a 4 bedroom new build: $700 to $1,200. Considerably cheaper than the cost of a break-in.
The sliding door problem
Sliding glass doors at the back of new build homes are a major weak point. The standard hooked latch is easy to defeat. Add an anti-lift pin and a key-operated bolt. Cost about $150 to $250 fitted. Big improvement.
Smart locks for new builds
If you want the convenience of smart locks plus the security upgrade, a Yale Assure or Lockwood Touch on the front door is a solid choice. Around $400 to $600 installed. Comes with backup keyway.
What to ask for
When you book a security assessment with a Pakenham locksmith, ask them to specifically check sliding doors, window locks, and the front door cylinder grade. Those three are where most builders save money and where you should spend a bit to improve security.
