Door Lock Types Explained: Which One Is Safest for Your Property?
When it comes to protecting your home or business, choosing the right door lock is one of the most important decisions you can make. With intruders becoming smarter and security technology evolving rapidly, homeowners need locks that offer durability, efficiency, and peace of mind. But with so many different lock types available, how do you know which is the safest for your property?
In this guide, experts at Doric Australia break down the most common door lock types, how they work, and which ones provide the best level of protection. Whether you’re upgrading your home security or searching for a reliable door lock near me, this article will help you make an informed choice.
Why Door Locks Matter More Today
Modern homes and commercial spaces require advanced security solutions. A high-quality door lock can:
- Prevent forced entry
- Protect valuables and occupants
- Enhance privacy
- Improve insurance compliance
- Provide long-term durability
Because different doors require different locking systems, it’s essential to understand your options before deciding.
Common Door Lock Types & Their Security Benefits
Below is a breakdown of the most popular door lock types used across Australia — and which are best for your property.
- Deadbolt Locks – The Gold Standard for Security
Deadbolts are one of the strongest and most secure lock types available. Unlike spring-latch locks, deadbolts cannot be easily opened with credit cards or force because they rely on a solid steel bolt.
Types of Deadbolts:
- Single-cylinder deadbolt: Key on the outside, thumb turn on the inside
- Double-cylinder deadbolt: Key required on both sides
- Electronic deadbolt: Operated with a code, keypad, or smart device
Why Deadbolts Are Safe:
- Resistant to physical attacks
- Hard to pick or tamper with
- Ideal for front and back doors
For maximum protection, many homeowners choose deadbolts from Doric Australia due to their high-quality materials and industry-tested construction.
- Mortice Locks – Premium Security for High-Traffic Doors
Mortice locks are embedded inside the door, making them highly durable and suitable for commercial buildings, apartment entrances, and premium residential doors.
Key Benefits:
- Extremely secure
- Difficult to force open
- Compatible with a range of handles
- Long-lasting mechanism
Mortice locks offer a superior balance between strength and aesthetics, making them one of the most reliable lock types on the market.
- Knob Locks – Common but Not the Securest
Knob locks are often used for interior doors, but they are not recommended as the sole security mechanism for external doors. The lock cylinder is placed inside the knob itself, making it vulnerable to forced entry.
Pros:
- Easy to install
- Suitable for bedroom and bathroom doors
Cons:
- Not secure enough for external doors
- Vulnerable to brute force
If you’re installing knob locks, use them only for inside rooms where privacy is more important than high-level security.
- Lever Handle Locks – Practical for Commercial & Residential Spaces
Lever handle locks are ideal for commercial properties and homes that require easy access. They comply with disability access standards and provide smooth operation.
Advantages:
- Easy to operate
- Ideal for offices, hallways, and high-use areas
- Can be paired with additional security locks
While lever handle locks offer convenience, they should be reinforced with deadbolts when used on external doors.
- Smart Locks – Modern Security with Digital Features
Smart locks are becoming increasingly popular in Australian homes and businesses.
Common features include:
- Keyless entry
- App control
- Temporary access codes
- Integration with home security systems
Why Smart Locks Are Safe:
- High encryption technology
- No need for physical keys
- Real-time monitoring
For convenience, smart locks are a great choice — but always choose reputable brands with strong cybersecurity protection.
- Sliding Door Locks – A Must for Patio & Balcony Security
Sliding doors are common in Australian homes, especially in living rooms and backyards. However, their standard locks are often not strong enough to withstand forced entry.
Best solutions include:
- Keyed sliding door locks
- Mortice-style sliding locks
- Drop bolts
- Interlocking slide mechanisms
Doric Australia specialises in durable sliding door lock solutions designed specifically for Australian weather, usage, and safety needs.
- Chain Locks & Latch Locks – Extra Layers of Security
These locks should not be used as the primary lock, but they provide additional protection.
Benefits:
- Allow you to check who is at the door
- Provide partial opening for ventilation or communication
Ideal for homes with elderly occupants or those wanting a simple secondary safety device.
How to Choose the Safest Door Lock for Your Property
A single lock type may not suit every door. Here’s how to choose correctly:
- Consider the Door Location
- Front & back doors: Deadbolts, mortice locks, smart locks
- Side doors & laundry doors: Deadbolts with knob or lever locks
- Sliding doors: Keyed sliding locks or drop bolts
- Interior rooms: Knob or lever handle locks
- Evaluate Security Needs
High-traffic or vulnerable areas require stronger locks with reinforced strike plates and deeper bolts.
- Look for Quality Materials
Choose locks made from:
- Hardened steel
- Brass
- Alloy metals
- Corrosion-resistant materials
High-quality materials increase longevity and tamper resistance.
- Ensure Proper Installation
The safest lock is only effective when installed correctly. Poor installation can weaken even the strongest lock.
