This is another one I’d keep and completely rebuild. The opportunity is to move away from generic “digital locks are convenient” content and explain what an experienced locksmith actually considers before fitting one.

I would also change the visible title from Choosing the Right Digital Lock to:

Choosing the Right Digital Lock: What You Need to Know Before Installation

A digital lock can be a great upgrade, but choosing one isn’t as simple as picking the lock with the most features.

The right digital lock needs to suit the door, existing lock preparation, environment, number of users and the way the property is actually used. A lock that’s perfect for a residential front door may be completely unsuitable for a busy commercial entrance.

At Lockwise Locksmiths, we install and work with mechanical and electronic locking systems across Brisbane Southside and Logan from our Hillcrest workshop. One of the most important things we’ve learned is that the digital features are only one part of choosing the right lock.

Before buying a digital lock, you need to consider the door and locking hardware first.

What Is a Digital Lock?

A digital lock allows a door to be unlocked using something other than—or in addition to—a conventional mechanical key.

Depending on the product, access might be provided by:

• PIN code
• Fingerprint
• Card or fob
• Smartphone
• Bluetooth
• Wi-Fi or another connected system
• Electronic credential
• Mechanical override key

Some digital locks are completely standalone. Others can connect to apps, smart-home systems or larger commercial access-control systems.

The important point is that “digital lock” describes a very broad category of products.

Two locks advertised as smart digital locks may have completely different capabilities, construction and intended applications.

What’s the Difference Between a Digital Lock and a Smart Lock?

The terms are often used interchangeably, but they don’t necessarily mean exactly the same thing.

A digital lock generally uses an electronic or coded method of access rather than relying solely on a traditional key.

A smart lock generally adds some form of connectivity or software-based control.

For example, a standalone keypad lock that opens after entering a PIN is digital, but it may not have any internet or smartphone connectivity.

A smart lock might allow authorised users to manage access through an app, receive notifications or integrate the lock with another system.

For many customers, the real question isn’t whether the product is technically a digital or smart lock.

It’s:

What do you actually need the lock to do?

Start With the Door, Not the Digital Lock

This is probably the most important advice we can give.

Customers sometimes purchase a digital lock online and then call a locksmith to install it, only to discover that it doesn’t properly suit their door.

Different locks have requirements relating to things such as:

Door thickness

Backset

Existing holes and preparation

Door handing

Lock type

Door and frame construction

Clearances

Existing hardware

A product looking good in a photo doesn’t mean it will work properly on your particular door.

Before buying a digital lock, it’s worth establishing whether it is physically compatible with what you have.

What Is Backset and Why Does It Matter?

The backset is essentially the distance between the edge of the door and the centreline of the main lock or spindle position.

Different locks are designed around particular dimensions.

This matters because an existing door may already have holes and cut-outs from its current lock.

A replacement digital lock needs to work with—or appropriately modify—that existing door preparation.

Installing the wrong lock can potentially leave old holes exposed or require unnecessary modification to the door.

This is one reason choosing a digital lock before looking at the door can create problems.

Not Every Digital Lock Is a Security Upgrade

This is another important distinction.

Replacing a conventional lock with an electronic one doesn’t automatically make the door more secure.

A digital lock primarily changes how access is authorised.

The physical security still depends on factors including:

• Lock construction
• Latching or deadlocking mechanism
• Door construction
• Door frame
• Strike
• Fixings
• Installation quality

A lock can have fingerprint recognition, Wi-Fi and a sophisticated app while still being poorly suited to the physical door it’s protecting.

Good security requires us to consider both access technology and mechanical security.

PIN Code Digital Locks

PIN locks are popular because they remove the need to issue a physical key to every person requiring access.

Instead, authorised users enter a code.

This can work well for homes, offices and other situations where several people need regular access.

Depending on the product, multiple user codes may be available.

Some systems can also provide temporary or time-limited codes.

The downside is that codes need to be managed properly.

If everyone shares one PIN indefinitely, access control can become little better than giving everyone the same physical key.

A PIN is still a credential. If someone who shouldn’t have access knows it, the code should be changed.

Fingerprint Locks

Fingerprint access can be extremely convenient.

There’s no key to carry and no PIN to remember.

However, biometric performance varies between products and environments.

A fingerprint reader should be selected based on more than a demonstration video.

Consider who will use it, how frequently the door is used and whether another method of access is available if a fingerprint can’t be read successfully.

For a household, fingerprint access may be primarily about convenience.

For a business, user management and access administration can become equally important.

Smartphone and App-Controlled Locks

Smartphone-connected locks can provide useful functionality.

Depending on the system, an app may allow users to manage credentials, provide temporary access or review certain lock activity.

But adding connectivity also adds another system that needs to be considered.

Ask questions such as:

What happens if the phone is flat?

What happens if the lock batteries are flat?

Does the lock still work without internet access?

Who controls the account?

How are users removed?

What happens when the property changes owners or tenants?

Is there another way to gain authorised access?

These questions are often more important than how impressive the app looks.

Bluetooth vs Wi-Fi Smart Locks

Not every connected lock communicates in the same way.

Some primarily use Bluetooth, requiring the authorised device to be relatively close to the lock.

Others can connect through Wi-Fi directly or through another hub or gateway, potentially allowing remote functions.

There are advantages and limitations to each arrangement.

Remote connectivity can be useful, but it also means the customer should understand what equipment and accounts the lock depends upon.

If remote operation isn’t actually required, paying for additional connectivity may provide little practical benefit.

What Happens When the Batteries Go Flat?

This is something every digital-lock owner should understand before the batteries go flat.

Battery-operated digital locks will eventually need replacement batteries.

Quality products normally provide some form of low-battery warning and may provide an emergency method of powering or accessing the lock.

Exactly how this works varies by model.

The important thing is knowing:

How does this particular lock behave when its normal power source is unavailable?

Don’t wait until you’re standing outside a locked door to read the manual for the first time.

Should a Digital Lock Have a Mechanical Key Override?

There isn’t one answer for every application.

A mechanical override can provide another method of authorised access if there’s an electronic problem.

But it also introduces a mechanical key cylinder into the security system.

If an override key is provided, that key needs to be stored and controlled properly.

Leaving the emergency key somewhere obvious near the door defeats the purpose of having controlled access.

For commercial applications, we may also need to consider whether the override cylinder should form part of an existing restricted or master key system.

What Happens During a Power or Electronic Failure?

This depends entirely on the lock.

Battery-powered standalone locks, electrically controlled commercial locks and smart-home products can behave very differently.

The system should be selected so its behaviour during a fault or power loss is appropriate for the application.

This becomes particularly important in commercial environments where access, egress and building requirements need to be considered.

It shouldn’t simply be assumed that every electronic lock should behave the same way.

Digital Locks on Front Doors

A residential front door is one of the most common places customers want digital access.

Convenience is a major advantage.

You may be able to enter without taking a key out, provide controlled access to family members or manage other authorised users.

But the front door is also a primary security point.

We therefore look at the existing door, frame, lock and strike, not simply whether a new digital product will fit over the old holes.

Sometimes a digital lock is a worthwhile upgrade.

Sometimes retaining a good mechanical deadlock and adding an appropriate digital solution provides a better arrangement.

The correct answer depends on the property.

Digital Locks for Rental Properties

Digital locks can offer useful functionality for some rental properties, but the system needs to be manageable.

Changing an access code can be considerably simpler than physically collecting numerous keys.

However, landlords and property managers should consider:

• Who administers the lock?
• How are credentials issued?
• How are previous users removed?
• Who maintains the batteries?
• What happens if the lock fails?
• Is emergency access available?
• Is the product appropriate for the door?
• What legal or tenancy requirements apply?

Technology doesn’t remove the need for good access-control procedures.

Digital Locks for Businesses

Commercial properties often have different requirements from homes.

A business may need to manage staff changes, different users, higher door traffic and controlled areas.

A standalone digital lock may be perfectly adequate for a small office or storeroom.

For a larger organisation, however, installing independent keypad locks on numerous doors can become difficult to manage.

At that point, a properly designed access-control system may make more sense.

The difference is scalability.

A single digital lock controls a door.

A well-designed access-control system can manage users, doors and access permissions as part of a larger system.

Digital Lock vs Access Control

These aren’t necessarily the same thing.

A standalone digital lock generally controls access at the individual door.

A commercial access-control system can potentially manage multiple doors and users from a central system.

Depending on the equipment, an administrator may be able to add or remove credentials and change access permissions without physically visiting every lock.

For a small premises, that complexity may be unnecessary.

For a school, factory or larger business, it can be extremely useful.

Digital Lock vs Restricted Key System

Electronic access isn’t automatically better than mechanical restricted keys either.

A restricted key system can provide strong control over the production of additional mechanical keys.

A digital system can provide different advantages around user credentials and administration.

And sometimes the best commercial solution is both.

For example, electronic access might control high-traffic entrances while restricted mechanical keys remain in use for selected internal doors, plant rooms or backup access.

We recommend systems based on the site’s actual requirements rather than assuming everything needs to become electronic.

What About Digital Deadlocks?

This is where terminology can become confusing.

Products advertised as digital locks can use very different locking mechanisms.

Some operate a deadbolt.

Some operate a latch.

Some interact with an existing mechanical lock.

Some replace much of the existing hardware.

So when comparing products, don’t simply look for the word “deadlock” in marketing material.

Look at how the lock actually secures the door and whether that mechanism is appropriate for the application.

Are Cheap Digital Locks Worth Buying?

Price alone doesn’t determine whether a product is good, but extremely cheap electronic locks deserve careful consideration.

With a conventional mechanical lock, you’re primarily relying on mechanical components.

With a digital lock you may also be relying on:

Electronics

Motors or actuators

Keypads

Fingerprint readers

Battery contacts

Firmware

Apps

Cloud services

Wireless communication

More features create more things that need to work correctly.

We’d rather install a product appropriate to the application than recommend something solely because it’s inexpensive or has an impressive list of features.

Don’t Choose a Digital Lock Based Only on Online Reviews

Reviews can be useful, but they don’t tell you whether the lock is suitable for your door.

A product might receive excellent reviews from customers installing it on a particular style of American residential door but be poorly suited to the door preparation commonly encountered in an Australian property.

Likewise, a lock that’s perfectly suitable for a lightly used residential door might not be our choice for a heavily used commercial entrance.

Product selection needs context.

Can a Digital Lock Be Installed on an Existing Door?

Often, yes.

But the amount of modification required varies.

Sometimes a suitable digital lock can integrate neatly with the existing preparation.

Other installations require alterations to the door and frame.

And sometimes the product a customer has purchased simply isn’t a sensible fit.

Where possible, we’d rather identify that before holes are drilled into the door.

Can You Replace an Existing Deadlock With a Digital Lock?

Potentially, depending on the existing lock, door and digital product.

But we wouldn’t automatically remove a good deadlock purely because a customer wants keypad or smart access.

There may be ways to achieve convenient digital entry while retaining appropriate mechanical security.

The entire locking arrangement should be considered rather than viewing the digital lock in isolation.

Outdoor Digital Locks and Weather Exposure

Not every digital lock is designed for the same environment.

A lock fitted to a protected internal office door experiences very different conditions from a lock exposed to Brisbane weather on an external gate or entrance.

Before installation, consider the manufacturer’s specified environmental suitability and which parts of the lock are actually weather resistant.

Electronic components and moisture are not a combination to take lightly.

Think About the People Who Will Actually Use the Lock

A technically impressive lock isn’t useful if the people relying on it find it difficult to operate.

A family home, rental property, office, school and factory can all have very different users.

Consider whether access will be used by:

Children

Older family members

Employees

Cleaners

Contractors

Tenants

Visitors

Property managers

The best access method should be practical for the people who need legitimate entry while still giving the owner appropriate control.

What Digital Lock Should I Buy?

There isn’t one digital lock we’d recommend for every door.

Before choosing one, determine:

1. What type of door do you have?

2. What lock is currently fitted?

3. Is it an internal or external door?

4. How many people need access?

5. Do you need PIN, fingerprint, card or smartphone access?

6. Do you genuinely need remote access?

7. Is this residential or commercial?

8. What happens when batteries or electronics fail?

9. Do you need to integrate it with an existing key or access system?

10. What level of physical security does the door require?

Answering those questions usually narrows the options considerably.

Digital Lock Installation Brisbane Southside & Logan

Lockwise Locksmiths is based at our Hillcrest workshop near Browns Plains, servicing homes and businesses throughout Brisbane Southside and Logan.

We work with mechanical locks, digital locking, restricted key systems, master key systems and access control, which means we can look at the complete security requirement rather than automatically recommending an electronic product.

If you’re considering a digital lock, you’re welcome to contact us before purchasing one.

Tell us what type of door you have, what lock is currently installed and what you want the new system to achieve.

A few photos can often help us understand the existing setup.

The best digital lock isn’t necessarily the one with the most technology. It’s the one that suits the door, the users and the security requirement.

Frequently Asked Questions About Digital Locks

Are digital locks more secure than normal locks?

Not automatically. Digital locks can provide better access-management features, but physical security still depends on the lock mechanism, door, frame, strike and quality of installation.

What happens if a digital lock battery goes flat?

It depends on the product. Many quality locks provide low-battery warnings and some form of emergency power or alternative authorised access. You should understand the procedure for your particular lock before relying on it.

Can a locksmith install a digital lock on my existing door?

Often, yes. Compatibility depends on the door, existing preparation and the digital lock being considered.

Should I buy a digital lock before calling a locksmith?

You can, but it’s often better to check compatibility first. This can prevent buying a lock that doesn’t suit the door or requires unnecessary modifications.

Are fingerprint locks better than PIN locks?

Neither is automatically better. Fingerprint access can be very convenient, while PIN access can be easy to issue and change. The right choice depends on the users and application.

Do businesses need digital locks or access control?

A standalone digital lock may suit a small business or individual door. Larger sites with multiple doors, users and access levels may benefit from a more comprehensive access-control system.
