A deadbolt provides significantly more security than a standard spring-latch lock because it cannot be forced open with a credit card or shimming tool. For most Australian homes, a single-cylinder deadbolt (keyed on the outside, thumb-turn on the inside) is recommended. If your door has glass panels near the lock, a double-cylinder deadbolt (keyed on both sides) prevents an intruder from breaking the glass and turning the thumb-turn.
Overview
Deadbolt installation is one of the most effective and affordable ways to improve the security of your home or business. Many Australian homes — particularly older ones — still rely on simple spring-latch locks that can be easily bypassed. A quality deadbolt extends a solid metal bolt deep into the door frame, providing strong resistance to forced entry. Australian locksmiths install a range of deadbolt types including single-cylinder, double-cylinder, and digital deadbolts from trusted brands like Lockwood, Yale, and Kaba. Proper installation is critical — a poorly fitted deadbolt or one installed in a weak frame offers reduced protection. A licensed locksmith ensures the bolt, strike plate, and frame reinforcement are all correctly installed for maximum security.

How it works
- 1
Door & Frame Assessment
The locksmith inspects your door material (timber, metal, or composite), door thickness, and frame condition to determine the correct deadbolt type and installation approach.
- 2
Deadbolt Selection
You choose from a range of deadbolts suited to your door and security requirements. The locksmith advises on single vs. double cylinder, security ratings, and features like anti-bump and anti-pick pins.
- 3
Precision Installation
The locksmith drills the necessary holes (if not already present), installs the deadbolt, reinforces the strike plate with longer screws that reach the door frame's structural timber, and ensures perfect alignment.
- 4
Testing & Demonstration
The deadbolt is tested multiple times for smooth operation. The locksmith demonstrates the correct use — including the thumb-turn, keyed operation, and how to check the bolt is fully extended.
How much does it cost?
Deadbolt installation in Australia typically costs between $150 and $350 per deadbolt, including labour and hardware. A standard single-cylinder Lockwood deadbolt installed on a timber door sits at the lower end ($150 to $220), while premium brands like Abloy or Mul-T-Lock with anti-pick and anti-bump features cost $250 to $350 or more. Installation on a metal door or a door that needs new holes drilled adds $30 to $60. Strike plate reinforcement kits add $20 to $40 but are highly recommended. If you are having multiple deadbolts installed, most locksmiths offer a reduced per-unit rate. After-hours installation attracts the standard emergency callout premium.
Australian regulations
Deadbolt installation in Australia must be performed by a licensed locksmith. In NSW, the required licence is Class 2F under the Security Industry Act 1997; in Victoria, a Private Security Licence under the Private Security Act 2004; in Queensland, a licence under the Security Providers Act 1993. Deadbolts on fire doors must comply with AS 1905.1 and the Building Code of Australia (BCA). Double-cylinder deadbolts (requiring a key to exit) should not be installed where they create a fire egress hazard, particularly in commercial properties or strata buildings. The Master Locksmiths Association of Australasia (MLAA) recommends deadbolts that meet or exceed AS 4145.2 for residential security.
