Ask someone what a locksmith does and the first answer is usually:

“You cut keys.”

And yes, we certainly do.

Key cutting is still an important part of locksmithing. At our Lockwise Locksmiths workshop in Hillcrest, we cut everything from everyday house and commercial keys through to automotive and specialist keys.

But modern locksmithing goes considerably further than duplicating a key.

A qualified locksmith works with the systems that control who can enter a home, business or vehicle. That can mean repairing a lock that’s been in a house for decades, designing a restricted master key system for a commercial property, programming a transponder key to a vehicle immobiliser or diagnosing why an ignition key won’t come out.

So what does a locksmith actually do?

Locksmiths Cut Keys – But Not All Keys Are the Same

Let’s start with the obvious one.

Key cutting can range from making a straightforward duplicate of an existing house key to considerably more specialised work.

Depending on the application, a locksmith may work with:

• Residential keys
• Commercial keys
• Restricted keys
• Master keys
• Automotive keys
• Transponder keys
• Motorcycle keys
• Older and classic vehicle keys
• Keys for specialist locking systems

Even conventional key cutting requires knowledge of the correct key profile, dimensions and locking system.

And sometimes copying the existing key isn’t actually the right approach.

If a key has been duplicated repeatedly over many years, for example, each generation can potentially reproduce wear or inaccuracies from the previous key. In some circumstances a locksmith can determine the correct key information and produce a more accurate key rather than simply tracing another worn copy.

Locksmiths Rekey Locks

This is one of the most useful locksmith services—and one that many people don’t realise exists.

Rekeying changes the lock so a different key operates it.

The complete lock doesn’t necessarily need to be replaced.

Depending on the lock design, a locksmith can alter its internal combination so the old key no longer operates it and a new key does.

Rekeying can be particularly useful after:

Moving house

Losing keys

Having keys stolen

Changing tenants

Employee changes

Unknown previous key copies

If the existing lock is good quality and serviceable, rekeying can often make more sense than throwing it away.

Not every lock is equally practical to rekey, however. Some are extremely difficult to reconfigure because of the way they’re manufactured.

A locksmith should be able to assess whether rekeying, repairing or replacing the lock is the better option.

Locksmiths Can Make Multiple Locks Work From One Key

Tired of carrying five keys for one property?

Compatible locks can often be keyed alike.

That means the same key might operate your front door, rear door and other selected locks.

This is different from a master key system.

With keyed-alike locks, the same key operates all the locks included in that group.

With a master key system, different keys can be given different levels of access.

That distinction becomes particularly important in commercial locksmithing.

Locksmiths Design Master Key Systems

Imagine a business with offices, storerooms, workshops and administration areas.

Not everyone should necessarily have access to everything.

A master key system can be designed so:

Employee Key → Selected employee areas

Supervisor Key → Additional areas

Manager Key → Broader access

Master Key → Multiple or all authorised areas

A properly designed system can significantly reduce the number of keys people need while still controlling access throughout a building.

Locksmithing at this level isn’t simply about cutting keys.

It involves designing an access hierarchy around the way the organisation actually operates.

Locksmiths Manage Restricted Key Systems

A standard key can potentially be copied without the property owner knowing.

For many businesses and organisations, that’s a key-control problem.

A restricted key system provides greater control over the authorisation and production of additional keys.

These systems are commonly used in:

• Businesses
• Schools
• Factories
• Warehouses
• Industrial sites
• Managed properties
• Body corporates
• Larger organisations

Restricted systems can also incorporate master keying, providing both controlled key duplication and different access levels.

Lockwise manages restricted and master key systems for commercial customers, and our involvement in professional locksmithing extends through industry organisations including the Master Locksmiths Association of Australasia and Locksmiths Guild of Australia.

Locksmiths Repair Locks

A lock that stops working doesn’t automatically need to be thrown away.

Depending on its construction, condition and availability of components, a locksmith may be able to repair it.

Problems can include:

Worn components

Broken components

Keys becoming difficult to operate

Locks sticking

Damaged cylinders

Door alignment problems

Damage following an attempted break-in

An important part of locksmithing is identifying whether the lock itself is actually responsible.

For example, a door that has dropped on its hinges can place pressure on a perfectly serviceable lock.

Replacing that lock without addressing the door alignment doesn’t necessarily fix the problem.

Locksmiths Install and Upgrade Locks

Sometimes replacement or upgrading is the right option.

Residential locksmith work can include installing or upgrading:

• Deadlocks
• Entrance locks
• Window locks
• Sliding-door locks
• Digital locks
• Smart locks
• Gate locks
• Garage access locks

But selecting a lock involves more than finding something that fits the hole.

The door, frame, strike, fixings and surrounding construction all contribute to physical security.

An expensive lock installed poorly on an unsuitable door doesn’t automatically provide good security.

Locksmiths Help Secure Homes After a Break-In

After a burglary or attempted break-in, the job isn’t simply to replace whatever looks broken.

A locksmith can assess:

The lock

Door

Frame

Strike

Fixings

Key security

Other vulnerable entry points

If keys were stolen, locks operated by those keys may also need to be rekeyed.

Sometimes the existing locks can be repaired and rekeyed.

Other times the damage exposes a weakness that makes upgrading the hardware sensible.

The objective is to restore security while understanding how the property was compromised in the first place.

Locksmiths Work With Digital and Smart Locks

Modern locksmithing increasingly combines mechanical and electronic security.

Digital locks may provide access using:

PIN codes

Fingerprint

Cards or fobs

Smartphones

Electronic credentials

But choosing a digital lock isn’t simply about selecting the model with the longest feature list.

A locksmith needs to consider the door thickness, backset, existing preparation, handing, environment, locking mechanism and physical security of the door.

For commercial properties, we may also need to determine whether a standalone digital lock is sufficient or whether a larger access-control system makes more sense.

Locksmiths Work With Access Control

Electronic access control allows businesses to manage entry without relying entirely on conventional mechanical keys.

Depending on the system, credentials can be issued to individual users and removed when they’re no longer required.

This can be particularly useful for organisations with multiple employees, doors or access levels.

But electronic access doesn’t automatically make mechanical locks obsolete.

Many good commercial security systems combine:

Access control + restricted mechanical keys + appropriate commercial locking hardware.

The correct combination depends on the property.

Automotive Locksmiths Make Car Keys

This is where modern locksmithing becomes substantially more technical.

A modern car key can contain several different elements.

There may be a:

Mechanical key blade

Transponder chip

Remote-control system

Proximity or smart-key system

Vehicle immobiliser

So making a replacement car key can involve much more than cutting the metal blade.

An automotive locksmith may need to cut the mechanical key, prepare the electronic key and program or authorise it to the vehicle.

Locksmiths Can Make Keys When All Car Keys Are Lost

You don’t necessarily need an existing car key for an automotive locksmith to make another one.

For many vehicles, we can produce a replacement when all keys have been lost.

The exact process varies by make, model and security system.

It may involve determining mechanical key information, cutting a new key and programming the appropriate transponder, remote or smart key to the vehicle.

Because the vehicle can’t be driven when all keys are lost, this work generally needs to be performed onsite.

For spare keys, bringing a driveable vehicle and its existing key to our Hillcrest workshop is usually the most economical option.

Locksmiths Program Transponder and Smart Keys

Most modern vehicles don’t rely solely on the physical shape of the key.

A correctly cut blade may open the door and turn the ignition, but the vehicle may still refuse to start unless it recognises an authorised electronic key.

Automotive locksmithing can therefore involve working with:

Transponders

Immobilisers

Remote keys

Smart/proximity keys

Vehicle security systems

This is very different work from conventional key duplication.

Locksmiths Repair Car Ignitions

A key that won’t turn doesn’t automatically mean you need a new key.

Likewise, a key stuck in the ignition doesn’t automatically mean the ignition barrel has failed.

Automotive locksmiths diagnose mechanical ignition problems including worn locks, damaged components and ignition housings.

We also encounter situations where the ignition is functioning correctly but another vehicle system is preventing the key from being removed.

Diagnosis matters.

Replacing a complete ignition assembly when a different component is actually responsible can be an expensive mistake.

Locksmiths Rekey Cars After Keys Are Stolen

Stolen car keys create a different security problem from lost keys.

Making another key doesn’t stop the stolen one from working.

Modern vehicles can have mechanical and electronic key security, and the two need to be considered separately.

Depending on the vehicle, an automotive locksmith may be able to remove the stolen electronic key from the vehicle’s authorised key system.

But if that key still physically operates the door lock, electronic deletion alone may not prevent someone from mechanically unlocking the vehicle.

That’s why stolen-key jobs can require both electronic key programming and mechanical lock rekeying.

Locksmiths Work With Motorcycle Keys

Motorcycles are another specialist area of automotive locksmithing.

Modern motorcycles can use transponder keys and immobiliser systems just like cars, while some higher-end systems involve complex relationships between keys, dashboards, immobilisers and electronic control units.

Lockwise works with motorcycle key replacement and programming, including lost and spare keys for many makes and models.

We also undertake more specialised motorcycle immobiliser work where appropriate.

Locksmiths Work on Classic Cars Too

At the other end of automotive locksmithing are classic vehicles.

A 50-year-old vehicle may not contain a transponder or immobiliser at all, but it can present its own challenges.

The key may be badly worn.

The ignition may have been replaced decades ago.

The doors and ignition may no longer use the same key.

The original key blank may be difficult to source.

The locks themselves may have decades of mechanical wear.

Classic automotive locksmithing can involve originating keys, identifying old key profiles, repairing original locks and determining what’s actually been changed during the vehicle’s history.

Sometimes old-fashioned mechanical locksmithing can be just as challenging as modern electronics.

Locksmiths Open Locked Doors and Cars

Yes, lockouts are still part of locksmithing.

A locksmith may help when you’re locked out of your:

House

Business

Car

or another secured property.

Professional locksmithing aims to use an appropriate entry method for the lock and situation rather than unnecessarily damaging the customer’s property.

But despite what movies often suggest, opening locks is only a small part of what a modern locksmith actually does.

Locksmithing Is a Security Trade

Ultimately, locksmithing is about controlling access.

The key might be mechanical.

It might contain a transponder.

It might be a restricted commercial key.

Or there may be no physical key at all because the door uses an electronic credential.

The underlying questions remain similar:

Who should be able to get in?

Who shouldn’t?

How is access controlled?

What happens when a key or credential is lost?

Can the system be repaired or reconfigured?

Is the physical hardware appropriate for what it’s protecting?

That’s why locksmithing now sits at the intersection of traditional mechanical skills, physical security and electronic access technology.

What Does a Qualified Locksmith Actually Need to Know?

A professional locksmith needs to understand considerably more than how to operate a key-cutting machine.

Depending on their area of work, that knowledge can include:

• Mechanical lock construction
• Keying and rekeying
• Master keying
• Restricted key systems
• Door hardware
• Physical security
• Digital locking
• Access control
• Automotive lock systems
• Transponders and immobilisers
• Vehicle key programming
• Fault diagnosis
• Safe entry techniques

No individual locksmith necessarily specialises equally in every part of the trade.

Like many trades, locksmithing has developed specialist areas.

At Lockwise, our work spans residential, commercial and automotive locksmithing, with particular experience in key systems, vehicle keys and more specialised automotive and motorcycle security work.

More Than Just Key Cutting

So, do locksmiths cut keys?

Absolutely.

We cut plenty of them.

But the person standing behind the key machine may also spend their day:

Rekeying a house after someone moves in.

Designing a restricted master key system for a business.

Repairing a damaged commercial lock.

Installing a digital lock.

Programming a replacement car key.

Rekeying a vehicle after keys are stolen.

Diagnosing a failed ignition.

Programming a motorcycle immobiliser.

That’s a much better picture of what modern locksmithing actually involves.

No. Those are two well-known locksmith services, but modern locksmithing covers residential and commercial security, electronic access, restricted key systems, vehicle immobilisers, transponder programming and many other specialist areas.

Can a locksmith change a lock without replacing it?

Often, yes. Many locks can be rekeyed, which changes the key that operates the lock without replacing the complete lock.

Can locksmiths make car keys?

Automotive locksmiths can make replacement and spare keys for many vehicles, including transponder, remote and smart keys. Many can also produce replacement keys when every existing key has been lost.

What’s the difference between a locksmith and an automotive locksmith?

Automotive locksmithing is a specialist area dealing with vehicle locks, keys and security systems. Modern automotive work can require knowledge of transponders, immobilisers, remotes, smart keys and electronic programming in addition to mechanical locksmithing.

Do locksmiths install digital locks?

Yes. Locksmiths can install many digital and smart locks, but the lock should be selected to suit the door, existing hardware, required security and how the property will use the access system.
