If you’ve just moved into a new Perth property — or you’re upgrading security after a break-in scare — choosing and installing the right lock is the single most important decision you’ll make for your safety. Get it wrong, and no amount of home insurance makes up for the stress of a compromised entry point.
What Types of Locks Can Be Installed on a Perth Home?
Understanding your options before you buy saves time, money, and headaches.
The most common residential choices are deadbolts and knob locks — and they’re not interchangeable. A deadbolt provides a solid bolt that extends deep into the door frame, making forced entry significantly harder. A knob lock alone on an external door is considered insufficient by most security professionals.

Beyond those basics, Perth homes and businesses can also be fitted with digital locks, keypads, magnetic locks, electric strikes, and mortice locks — all of which Ultimate Lock installs across the Perth metro area. Each type suits a different door material, usage frequency, and security rating.
Older Perth homes — particularly those built before the 1990s — often have outdated lock cylinders that no longer meet current security standards. If you’re moving into an established property, a lock inspection should be your first call.
When Should You Install New Locks vs. Just Rekey Existing Ones?
The right answer depends on your lock's condition and your specific security situation.
Rekeying changes the internal pin configuration so old keys no longer work — without replacing the lock hardware. It’s faster and typically less expensive than a full replacement. If your locks are in good physical condition, rekeying is the smarter move after buying a new home, since previous owners, contractors, or real estate agents may still hold copies of your keys.
Full lock installation makes sense when locks are visibly damaged, outdated, or you want to upgrade to a higher security rating or a digital system. Our related article Top 5 Signs Your Perth Home Needs New Locks Installed Right Away covers the specific warning signs to watch for.

What Does Lock Installation Actually Involve?
Step-by-step so you know exactly what to expect on the day.
Step 1: Assessment. A licensed locksmith inspects the door, frame, and existing hardware to confirm compatibility with the new lock. Door thickness, material, and backset measurements all affect which products will fit correctly.
Step 2: Preparation. If it’s a new installation rather than a replacement, the locksmith marks and drills the required bore holes. Precision here is critical — an incorrectly sized hole weakens the door structurally and can void manufacturer warranties.
Step 3: Fitting and testing. The lock is seated, the strike plate is positioned into the frame, and the locksmith tests full operation under load before handing over keys. A properly installed lock should operate smoothly with no stiffness or misalignment.
Should You DIY Lock Installation or Hire a Perth Locksmith?
Honest answer: it depends on the lock type and what's at stake.
Basic interior door knob replacements are within most people’s DIY capability. But external door locks, deadbolts, and any electronic or commercial-grade hardware carry a much higher margin for error. A misaligned deadbolt, for example, may appear to work fine — until it jams at the worst possible moment or fails to deter a forced entry attempt.
In Western Australia, locksmiths must hold a valid licence — Ultimate Lock holds Police License SA51285 and Installers License SG33024. Hiring a licensed professional also ensures any warranty on the lock product remains valid. Our dedicated article Can You Install Your Own Locks? DIY vs Hiring a Perth Locksmith Explained goes deeper on where the line sits.
If you’re comparing quotes, ask each locksmith for their licence numbers upfront. A legitimate Perth locksmith will provide them without hesitation — and you can verify them with WA Police licensing records.
What Are the Lock Installation Needs for Perth Businesses?
Commercial security requirements go beyond a standard front door deadbolt.
Commercial clients — including offices, body corporates, retail premises, and government facilities — often require access control systems, master key hierarchies, magnetic locks, and panic exit devices. These systems allow different staff members to access different areas without duplicating keys endlessly.
Ultimate Lock services commercial clients across Perth including small firms, real estate agents, and government properties. Digital locks and fingerprint readers are increasingly common in commercial fitouts, offering audit trails that a physical key simply cannot provide.
- •Mortice locks — high-security option built into the door body itself
- •Electric strikes — allow remote or access-card controlled entry
- •Magnetic locks — fail-safe operation, commonly used on fire egress doors
- •Panic exit devices — legally required on many commercial exit doors
- •Digital keypads — eliminates key duplication risk for high-turnover staff environments
How Much Does Lock Installation Cost in Perth?
Pricing varies significantly depending on lock type, door condition, and urgency.
Installation cost depends on the type of lock, number of doors, and whether any carpentry or frame repair is needed. A straightforward deadbolt swap costs considerably less than a full commercial access control installation. For a detailed breakdown, our related article How Much Does Lock Installation Cost in Perth? An Honest Price Breakdown walks through what to expect for common scenarios.
Ultimate Lock offers transparent, upfront pricing with no hidden call-out fees hidden in the fine print. The best approach is always to request a quote before work begins — which you can do directly via phone or the contact form.
Lock Installation in Perth: Your Questions Answered
Common questions from Perth homeowners and business owners about lock installation.
How long does a professional lock installation take?
A standard single deadbolt replacement typically takes 30 to 60 minutes for an experienced locksmith. More complex installations — such as digital locks or commercial access control systems — can take several hours depending on the number of doors and any additional wiring or hardware required.
Can a locksmith install locks on any door type?
Most licensed locksmiths can work with timber, aluminium, and UPVC doors, though the lock products compatible with each material differ. Always confirm your door type when requesting a quote so the right hardware is brought to the job — arriving with the wrong product wastes everyone’s time.
Is it worth installing high-security locks on internal doors?
For most residential properties, high-security locks on external entry points deliver the greatest return on investment. Internal door locks are generally lower grade since they serve as a secondary barrier. The exception is home offices, server rooms, or any space storing high-value items — those warrant a more robust solution.
