Are Deadbolts More Secure Than Standard Door Locks in Perth?

In many situations, a properly installed deadbolt can provide a higher level of resistance to forced entry than a basic latch-style door lock. However, the lock itself is only one part of your overall door security. The quality of the door, frame, strike plate, installation and other security measures can make a significant difference.

For Perth homeowners, landlords and businesses, choosing the right lock should be about more than simply buying the strongest-looking product. You need a lock that suits the door, provides appropriate security and can still be used safely and conveniently every day.

Western Australian government guidance recommends deadlocks as one of the practical ways to improve home security. WA rental security requirements also recognise deadlocks as a minimum security option for many external doors.

At Sheehan Locksmiths Perth, we help property owners understand their existing locks and choose practical security solutions for homes and businesses throughout Perth.

What Is a Deadbolt?

A deadbolts, commonly called a deadlock in perth, is a type of door lock that uses a solid locking bolt rather than relying only on a spring-loaded latch.

When the deadbolt is locked, the bolt extends into the door frame or strike area. Unlike a typical spring latch, a deadbolt does not simply retract because pressure is applied to the door.

Deadbolts are available in different designs, including:

• Single-cylinder deadbolts
• Double-cylinder deadbolts
• Deadbolts incorporated into door hardware
• Key-operated deadlocks
• Some electronic and digital deadbolt-style locks

The correct option depends on the door, property layout, security requirements and safe exit considerations.

For example, WA guidance notes that a single-cylinder deadlock can generally be opened from inside by turning the knob or handle, allowing occupants to exit quickly during an emergency.

What Is a Standard Door Lock?

A standard door lock often uses a spring-loaded latch that keeps the door closed when it is shut.

These locks are useful for everyday access and can be perfectly suitable for many internal doors or situations where higher security is not the main concern.

However, a basic latch lock may not provide the same level of resistance to certain forms of forced entry as a properly installed deadbolt.

This does not mean every standard door lock is weak or every deadbolt is automatically secure. Lock quality varies considerably.

A high-quality standard lock installed correctly may provide good security, while a poorly installed deadbolt on a weak door or frame may not perform as expected.

That is why the complete door system matters.

Are Deadbolts Actually More Secure?

Generally, yes — a quality deadbolt can provide stronger physical security than a basic latch-only lock.

One major reason is the locking bolt.

A deadbolt uses a solid bolt that extends into the strike plate or door frame. This can make it more difficult for an intruder to force the door open by manipulating the latch.

However, security is not determined by the lock alone.

A properly secured entrance should ideally consider:

• Lock quality
• Door strength
• Door frame condition
• Strike plate and fixing
• Hinge security
• Glass near the lock
• Security screens where appropriate
• Correct installation
• Key control
• Overall property security

The City of Vincent’s security guidance, for example, recommends solid entrance doors or security doors with appropriate deadlocks, while also highlighting other measures such as lighting, protected hinges, alarms and CCTV.

Deadbolt vs Standard Door Lock: Key Differences

Here is a simple comparison:

The important point is that “deadbolt” does not automatically mean “best possible security.”

The quality of the complete installation still matters.

Why Deadbolts Can Improve Perth Home Security

Perth properties can have very different security requirements. A suburban family home, apartment, rental property, investment property and commercial premises may all need different locking solutions.

A properly selected deadbolt can offer several advantages.

1. Stronger Physical Locking

The main benefit is the solid bolt mechanism.

When engaged correctly, the bolt extends into the door frame rather than simply holding the door closed with a spring latch.

2. Better Protection for External Doors

External doors are usually the most important doors to secure.

A deadbolt can provide an additional layer of protection on:

• Front doors
• Back doors
• Side entrances
• Garage access doors
• Commercial entry doors
• Other external doors

WA’s residential rental security requirements identify a deadlock as one of the accepted minimum security arrangements for the main entry door.

3. Useful Security Upgrade

If an older Perth property currently has only a basic latch lock, upgrading the entry door may improve its overall security.

Depending on the door, an upgrade could involve installing a deadbolt, replacing worn hardware, strengthening the strike area or replacing the entire lock.

4. Different Options Are Available

Homeowners are not limited to traditional key-operated locks.

Depending on the door and security requirements, options can include:

• Traditional deadlocks
• High-security locks
• Digital locks
• Smart locks
• Keyed-alike systems
• Restricted key systems
• Combination locking solutions

A locksmith can assess which option is appropriate rather than simply recommending the same lock for every property.

Are Standard Door Locks Always Less Secure?

Not necessarily.

The phrase “standard door lock” covers a wide range of products. Some modern locks are designed with stronger materials, improved cylinders and better resistance to common attack methods.

The bigger issue is whether the existing lock provides an appropriate level of security for its location.

For example, a basic internal bedroom lock does not need the same security characteristics as the main entrance to a Perth home.

Similarly, a commercial premises containing valuable equipment may require more sophisticated access control than a standard residential entry.

So rather than asking only, “Is this a standard lock?”, it is better to ask:

“Does this lock provide an appropriate level of security for this particular door and property?”

The Door Frame Matters Too

One common mistake is concentrating entirely on the lock.

A strong lock installed into a weak door frame may not provide the expected level of protection.

The strike plate, screws, frame and surrounding structure all contribute to the strength of the locking system.

During a security assessment, these areas should be considered together.

A professional locksmith can identify problems such as:

• Loose strike plates
• Damaged door frames
• Misaligned doors
• Worn locking mechanisms
• Weak or damaged hardware
• Poorly fitted locks
• Doors that do not close correctly

Fixing these problems may sometimes improve security more than simply installing a new lock.

Single-Cylinder vs Double-Cylinder Deadbolts

Another important consideration is the type of deadbolt.

A single-cylinder deadbolt generally uses a key on the outside and a thumb turn or similar mechanism on the inside.

A double-cylinder deadbolt typically requires a key from both sides.

Double-cylinder designs can offer particular security advantages in situations where an intruder could potentially reach an inside thumb turn through nearby glass.

However, there is an important safety consideration: needing a key to exit can create an emergency egress issue.

For that reason, the right choice should consider both security and safe exit.

WA guidance specifically recognises single-cylinder and double-cylinder deadlocks, while noting the emergency-exit benefit of single-cylinder designs.

What About Smart Deadbolts and Digital Locks?

Technology has changed the way Perth homeowners think about door security.

Digital and smart locks can provide features such as:

• PIN access
• Smartphone access
• Temporary codes
• Keyless entry
• Access management
• Automatic locking
• Activity notifications on some systems

However, smart does not automatically mean more secure.

A digital lock still needs appropriate installation, reliable hardware and good security practices.

Homeowners should also consider what happens if:

• The battery goes flat
• The electronic system fails
• A code is shared
• A smartphone is lost
• The lock requires emergency access

A locksmith can help determine whether a digital lock is suitable for your particular door.

Should You Replace Your Standard Lock With a Deadbolt?

A deadbolt upgrade may be worthwhile if your existing external door lock is:

• Old or worn
• Loose
• Difficult to operate
• Providing only basic security
• Damaged after an attempted break-in
• No longer suitable for your security requirements

You may also consider an upgrade after moving into a new property.

In that situation, rekeying or replacing locks can help you regain control over who has access to the property.

For rental properties, tenants should also understand the relevant WA rules before changing or adding security devices. Consumer Protection WA states that tenants generally need permission from the landlord to change or add security devices, subject to specific circumstances.

How to Make Your Door More Secure

Installing a deadbolt is only one part of a good security plan.

Consider the following:

Use quality locks

Choose locks appropriate for the door and the level of security required.

Check the door frame

A damaged or weak frame can reduce the effectiveness of even a good lock.

Secure other external doors

Do not focus only on the front entrance. Back, side and garage doors should also be considered.

Improve visibility

Good exterior lighting can make it harder for someone to approach a door unnoticed.

Consider security screens

A properly selected security screen can provide an additional layer of protection.

Maintain your locks

A lock that sticks, jams or fails to latch correctly should be inspected rather than ignored.

Control your keys

If keys have been lost, stolen or distributed to too many people, consider rekeying or replacing the relevant locks.

WA security advice also recommends combining door security with measures such as security screens, lighting, alarms and CCTV rather than relying on a single security product.

When Should You Call a Locksmith in Perth?

You should consider professional assistance when you are unsure whether your current locks provide adequate security or when a lock is damaged or failing.

Final Verdict: Are Deadbolts More Secure Than Standard Door Locks in Perth?

In many cases, yes. A quality deadbolt can provide stronger physical security than a basic standard latch lock, particularly when used on an external entry door.

But the deadbolt itself is not the entire security solution.

The door, frame, strike plate, hinges, installation and surrounding security measures all influence how well an entrance is protected.

For Perth homeowners, the best approach is to look at the complete door security system rather than choosing a lock based only on appearance or price.

If your current lock is old, damaged or providing only basic protection, a professional assessment can help determine whether a deadbolt, high-security lock, digital lock, rekeying or another upgrade is the better option.
