Home Security Locks in Perth — Upgrading for Better Protection

Most Perth homes leave the factory with basic builder-grade locks that meet minimum code requirements but aren't particularly difficult to defeat. Upgrading your locks is one of the most cost-effective security improvements you can make — and a licensed locksmith can advise you on what's appropriate for your property.

Understanding the Australian Standard

Lock quality in Australia is rated under AS 4145. Grade 1 (highest) locks offer the strongest resistance to physical attack and key duplication. Grade 6 (lowest) are builder-grade entry locks. For a Perth home, Grade 1 or Grade 2 deadbolts on external doors are recommended. Ask your locksmith specifically whether the locks they're recommending meet AS 4145 Grade 1 or 2.

Deadbolts

A deadbolt is the most important lock on any external door. Unlike spring latches (which can be defeated with a credit card), a deadbolt throws a solid steel bolt into the door frame that can only be retracted with a key or thumb-turn. Single-cylinder deadbolts (keyed outside, thumb-turn inside) are standard for most doors. Double-cylinder deadbolts (keyed on both sides) provide more security but are not recommended near glass panels — in an emergency you may need to exit quickly.

High-Security Lock Brands

In Australia, brands worth considering include Lockwood (Australian, widely available, good grade 1 options), Abloy (Finnish, disc-detainer mechanism, extremely pick-resistant), and Medeco (American, high security, patented keyways). These cost more than builder-grade locks but make a genuine difference to your security level and key control.

Smart Locks

Smart locks (keypads, Bluetooth/app access, fingerprint) are increasingly popular in Perth homes. The convenience is real, but security varies significantly by brand. Ensure any smart lock you install also has a physical key override — app or battery failure shouldn't lock you out of your own home. Brands like Schlage, Yale, and Danalock have a good security reputation.
