Door locks and handles in Australian construction: types, AS 4145 ratings, brands

TL;DR

Door locks and handles span a wide product range from simple privacy latches (toilet doors) through to high-security multi-point locking entry systems. The Australian security rating standard is AS 4145.2:2008, which classifies locks from 1-star (minimum) to 6-star (highest) based on durability, key cycle resistance, and forced-entry resistance. Volume residential entries in Australia use 3-star or 4-star locks; 5-star and 6-star are insurance-specified high-security applications. Class 2 apartment entry doors and Class 5-9 commercial entries usually step up to 4-star or higher and add fire-rated mortice hardware where the door forms part of an FRL-rated assembly. Five lock-and-handle categories cover virtually all applications: passage sets (no lock; corridor/internal doors), privacy sets (bathroom/bedroom, simple thumb-turn), entry sets (lock + lever or knob; standard front entry), deadlocks (separate key-only lock; security upgrade), and electronic / smart locks (keyless, Bluetooth, NFC, PIN). Lever handle compliance under AS 1428.1:2021 is mandatory in Australian buildings designed to be accessible (Class 1b plus parts of multi-residential); the round knob is non-compliant because someone with hand-mobility impairment cannot grip and turn it. The Australian volume brands are Lockwood (ASSA ABLOY, the dominant entry-lock brand), Whitco (sliding door and security hardware specialist), Yale, Schlage, and Brava. The two job-killers: specifying a 1-star or 2-star lock at an external entry door (fails AS 4145 minimum for forced-entry resistance; insurance won’t pay out on a burglary), and using a non-compliant handle (round knob) on a DDA-required accessible doorway.

What it is

Door hardware covers the latching, locking, and handle mechanism on every interior and exterior door across Class 1a, Class 2, and Class 3-9 construction. The Australian security standard is AS 4145.2:2008, which sets test procedures and classification for mechanical locks. Disability access requirements sit under AS 1428.1:2021 (lever vs knob); fire-rated door hardware sits under AS 1530.4:2014 test methods.

The main categories of door hardware:

Category	Where used	Function
Passage set	Internal corridor doors	Latch only; no lock
Privacy set	Bathroom, ensuite, bedroom	Latch + simple thumb-turn lock (no key); coin-slot emergency release
Entry set (lock + lever or knob)	Front entry, garage internal, side door	Latch + key-operated cylinder lock; deadbolt optional
Deadlock (standalone)	Front entry security upgrade; secondary lock	Separately keyed deadbolt; typically paired with an entry set or passage set
Mortice lock	Older homes, premium entry doors	Lock mortised into door edge; key-operated
Electronic / smart lock	Premium entry, multi-tenancy access control	Keyless via PIN, key fob, Bluetooth, NFC; battery-powered
Multi-point lock	Premium entry doors, security upgrades	3-point or 5-point locking from a single key turn

AS 4145 security rating

AS 4145.2:2008 tests locks on multiple criteria and assigns a star rating from 1 to 6:

Rating	Test criteria	Where used
1-star	Basic durability test	Cabinet locks, low-security internal applications
2-star	Higher durability, basic forced-entry	Internal doors, secondary doors
3-star	Standard residential durability + forced-entry	Volume residential front entry
4-star	Enhanced durability + forced-entry	Premium residential, security-conscious entries
5-star	High security + extended durability	Insurance-specified, high-risk locations
6-star	Maximum security	Specialist commercial, high-net-worth residential

A typical residential front-entry deadbolt is rated 3-star or 4-star. Going below 3-star on an external entry door fails insurance compliance in many policies. The star rating is on the product packaging and data sheet; verify before installing on any external door.

AS 1428.1: DDA compliance

AS 1428.1:2021 (Design for access and mobility) requires that door hardware be operable by a person with limited hand mobility. The key requirements:

Requirement	Where it applies
Lever handle (not round knob)	Any door in an accessible path of travel; mandatory in Class 1b accommodation, Class 2 dwelling entries, Class 9 (commercial)
One-handed operation	The handle must be operable without grasping, pinching, or twisting; the wrist alone must be sufficient
Maximum operating force	Less than 19.5 N to operate
Lever return length	The lever must not project more than 100 mm from the door face; sharp ends are non-compliant
Mounted height	Handle centreline 900 to 1100 mm from finished floor level
Push plate / pull plate alternative	Acceptable on certain doors instead of lever

For Class 1a (standalone houses), DDA compliance is not strictly required, but increasingly volume residential builders apply lever-handle compliance throughout for future-proofing and consistency. Class 1b (boarding houses, hostels) and Class 2 (apartment dwellings) typically require AS 1428.1 compliance on accessible-path doors per NCC Part D3 (Access and egress).

Australian manufacturers

Brand	Market position	Range
Lockwood (ASSA ABLOY)	Dominant Australian residential entry lock	Full residential range: deadlocks, entry sets, electronic

For volume residential builds, Lockwood is the dominant single-brand specification. Specifier-led projects often mix brands by application (Yale electronic at the front, Lockwood deadbolts on secondary doors, Whitco on sliding doors).

Categories in detail

Passage sets

The simplest hardware: a latch that engages with the strike plate to hold the door closed, operated by a lever or knob from either side. No lock. Typical fitting cost in 2026: $40-80 per door.

Privacy sets

A latch with a thumb-turn lock from inside (no key); a small coin-slot release from outside for emergencies. Bathroom and bedroom doors. Typical cost: $50-100 per door.

Entry sets

Combine a key-operated lock cylinder with a lever or knob. Standard front-entry hardware:

Sub-category	Description
Cylindrical lockset	Lock mechanism in the door knob/lever itself; volume residential
Tubular latch + separate lock cylinder	Two-piece; lock and latch separate
Mortice lockset	Lock mortised into the door edge; premium
Deadlatch + deadbolt	Cylindrical + separate deadbolt for added security

Typical AS 4145 rating: 3-star or 4-star. Cost: $80-280 per door.

Standalone deadlocks

Single-cylinder or double-cylinder deadbolts. Double-cylinder (key on both sides) is more secure but is a fire-egress concern (occupant cannot exit without key in a fire); many states discourage double-cylinder in residential.

Typical cost: $80-220 per lock.

Multi-point locks

Premium European-style entry locks that engage 3 to 5 points on the door frame from a single key turn. Common on imported European-style doors and high-security upgrades. Cost: $300-800+ per lockset.

Electronic / smart locks

Type	Operation
PIN keypad	Code entry; battery-powered
Bluetooth / smartphone	Phone proximity unlocks
NFC / RFID card	Card or fob proximity
Biometric (fingerprint)	Fingerprint reader
Hybrid (keypad + key)	Both options for backup

Examples: Yale Assure, Lockwood Cortex, Schlage Encode, August Smart Lock. Battery life typical 6-12 months; backup key entry typically included.

Cost: $300-1,200+ per lock.

Fire-rated door hardware

Doors in fire-rated walls (typically inter-tenancy boundaries, garage-to-house) need fire-rated hardware tested as part of the tested-door-assembly under AS 1530.4:2014. The hinges, lock, latch, seal, and self-closer must all meet the FRL rating.

FRL rating	Typical application
FRL-30	Some Class 1 garage-to-house doors
FRL-60	Inter-tenancy (apartment, townhouse)
FRL-90	Higher-rise multi-residential
FRL-120	High-rise commercial overlap

Generic residential hardware is not fire-rated. Use only hardware specifically certified for the door assembly’s FRL.

Common defects and on-site issues

Wrong AS 4145 rating on external door: 2-star or 1-star fitted to a front entry. Insurance compliance failure. Always 3-star minimum on external doors; 4-star recommended.
Round knob on DDA-required door: Class 1b or Class 2 entry with a knob instead of a lever. Compliance defect.
Double-cylinder deadbolt on egress door: occupant cannot exit in fire without key. Use single-cylinder + thumb-turn from inside.
Lever handle return too long or sharp: clothing snag risk; DDA non-compliant if over 100 mm projection. Use compliant lever profiles.
Self-closer omitted on fire-rated door: door doesn’t close after use, fire compartment not maintained. Mandatory on FRL-rated doors.
Strike plate not aligned: door doesn’t latch properly; slams or fails to close. Realign strike plate or adjust hinge position.
Drill-out vulnerability: cheap deadbolts can be drilled out in seconds. AS 4145 3-star+ products include anti-drill plates.
Electronic lock battery flat: occupant locked out; smart lock without physical key backup is a real risk. Always specify hybrid with key backup.
Patio sliding door lock orientation wrong: Whitco-style sliding patio door locks are handed (left vs right). Confirm at order.
