Deadbolts vs Standard Locks: Which Offers Better Security?

Not all locks offer the same level of protection. Many Melbourne homes still rely on basic door handle locks, while others have upgraded to deadbolts or more advanced systems.

A common question homeowners ask is whether a standard lock is enough or if a deadbolt is worth the upgrade.

The answer depends on how the lock works, where it is used, and the level of security you want.

We’re a professional locksmith based in Melbourne, and with our years of experience, we’ll offer our advice.

Let’s start with the basics…

How Each Lock Mechanism Works

Standard locks, often built into door handles, use a spring-loaded latch. When you turn the handle, the latch retracts, allowing the door to open. When released, it snaps back into place.

While convenient, this design relies on spring tension, which makes it easier to force open under pressure.

Deadbolts operate differently. Instead of a spring, they use a solid metal bolt that extends deep into the door frame when locked. This bolt must be manually turned using a key or thumb turn, making it far more resistant to force.

Because of this fundamental difference, deadbolts are generally considered the more secure option for external doors.

Strength and Resistance to Forced Entry

The biggest advantage of a deadbolt is its resistance to physical force. Because the bolt is solid and not spring-loaded, it cannot be easily pushed back or slipped open.

Standard locks, on the other hand, are more vulnerable to techniques such as “loiding,” where a thin object is used to push the latch back. They are also more susceptible to damage if pressure is applied to the door.

Cost Differences Between Deadbolts and Standard Locks

Standard locks are generally less expensive because they are simple and often included with the door hardware.

Deadbolts tend to cost more upfront, both for the hardware and installation. However, they offer a higher level of security, reducing the likelihood of forced entry.

In many cases, the cost difference is relatively small compared to the potential cost of a break-in. For that reason, many homeowners choose to install both, using a standard lock for convenience and a deadbolt for security.

Best Use Cases for Each Lock Type

Deadbolts are best suited for external doors, including front, back, and garage entry points. They provide the primary line of defence against unauthorised access.

Standard locks are more appropriate for internal doors, where convenience is more important than high security. They can also be used on external doors when paired with a deadbolt.

In practice, most secure homes use a combination of both rather than relying on a single locking mechanism.

Pros and Cons of Deadbolts and Standard Locks

Deadbolts offer stronger protection and are more resistant to forced entry, but they require manual operation and can cost slightly more to install.

Standard locks are simple and convenient to use, but they offer lower security when used on their own.

The right choice depends on where the lock is being installed and the level of protection needed.

Choosing between a deadbolt and a standard lock is not about selecting one over the other. It is about using the right combination.

For most homes, especially in Melbourne, a deadbolt should be considered the minimum standard for external doors, while standard locks can continue to serve as secondary or internal locks.

If your current setup relies only on a basic latch lock, upgrading to a deadbolt can significantly improve your home’s security.

Deadbolts and standard locks serve different purposes, but when it comes to security, deadbolts provide a clear advantage for external doors.

Standard locks are convenient, but they should not be relied on as the primary line of defence.
