Your Complete Guide to Lock Installation for Home and Business

Whether someone is moving into a new home in Rockingham, managing rental properties in Mandurah, or upgrading security at a commercial premises in Kwinana, professional lock installation is one of the most important investments a property owner can make. Getting it right from the start means choosing the correct lock type, fitting it precisely to the door and frame, and knowing that the work is backed by a licensed, experienced locksmith. This guide covers everything local homeowners, landlords, and business owners need to know about lock installation in the Rockingham-Mandurah coastal region.

Types of Locks Available for Residential and Commercial Properties

One of the first decisions in any lock installation project is choosing the right lock type for the door, the property, and the level of security required. A qualified locksmith can help match the right hardware to the application, but understanding the main options is a great starting point.

• Deadbolts: A popular choice for external doors, deadbolts offer solid resistance to forced entry because the bolt cannot be retracted without a key or thumbturn. They are commonly fitted to front and back doors on residential properties.
• Deadlatches: These combine a spring latch with a deadlocking mechanism, making them convenient for everyday use while still offering strong security. They are widely used on entry doors across homes and apartments.
• Mortice locks: Recessed into the door body itself, mortice locks provide a clean, robust solution often seen on timber doors in older homes and commercial buildings.
• Security door and screen door locks: Designed specifically for aluminium and steel security screen doors, these locks require specialist fitting to ensure the frame is not weakened during installation.
• Window locks: Sash locks, key-lockable window stays, and keyed window bolts all add an important layer of security to sliding and hinged windows.
• Padlocks: From high-security padlocks for sheds and gates to restricted key padlocks for commercial yards, the right padlock fitted to quality hasps makes a real difference.
• Restricted key system locks: These locks use patented key profiles that cannot be duplicated at a hardware store, making them ideal for businesses and rental properties where key control matters. Learn more about master key and restricted key systems for business applications.

What Happens on the Day: The Lock Installation Process

A professional lock installation is not simply a matter of drilling a hole and screwing in hardware. A thorough process protects the door, the frame, and the long-term function of the lock.

1. Door and frame assessment: Before any fitting begins, the door material, thickness, swing direction, existing hardware cutouts, and frame condition are all checked. This step prevents misaligned strikes, poor backsets, and damaged doors.
2. Lock selection or compatibility check: If the customer is supplying their own hardware, compatibility is verified on-site. If the locksmith is supplying the lock, the right product is selected based on the assessment.
3. Fitting and installation: The lock is fitted with precision, including any necessary chiselling, drilling, or plate installation. Strike plates are properly aligned and secured with long screws into the door frame for added strength.
4. Testing and adjustment: Once fitted, the lock is tested multiple times from both sides, the latch and bolt travel are checked, and any adjustments are made before the job is considered complete.
5. Key handover: All keys are handed over and accounted for, and the customer is shown how to operate the lock correctly, including any thumbturn or emergency release features.

Master Lock Service operates as a fully mobile locksmith, coming directly to the property in Rockingham, Mandurah, Kwinana, and the surrounding coastal suburbs. There is no need to remove a door or travel anywhere.

Why Lock Installation in WA Must Be Done by a Licensed Security Installer

This is a point that many property owners in Western Australia are not aware of: lock installation is classified as security work under WA law, and it must be carried out by a person holding a current Security Installers Licence issued by the WA Police. Using an unlicensed handyman or tradesperson to install security hardware can have serious consequences.

First, home and contents insurance policies often include clauses requiring that security hardware be installed by a licensed professional. If a break-in occurs and an insurer discovers the lock was fitted by an unlicensed person, a claim could be denied. Second, warranty coverage on quality lock brands typically requires professional installation. Third, an improperly fitted lock, even if it looks fine on the surface, may fail under pressure or allow unauthorised entry.

Master Lock Service holds Security Installers Licence 39859 and Security Agents Licence 39858, both issued by WA Police. With over 30 years of hands-on locksmithing experience and full police licensing, customers in the Rockingham-Mandurah region can be confident that every installation meets the legal and professional standard required.

Can a Handyman Legally Install Locks in WA?

In short, no. Under WA security industry legislation, installing locks and security hardware requires a valid Security Installers Licence. A general handyman, builder, or unlicensed tradesperson is not permitted to carry out this work legally. Beyond the legal question, there is the practical matter of skill and experience. Fitting a lock incorrectly, even by a small margin, can compromise the entire security of a door.

Lock Installation for Homeowners Moving Into a New Property

Moving into a new home is an exciting milestone, but one security step that is easy to overlook is changing or rekeying the locks. The previous owners, tenants, tradespeople, real estate agents, and neighbours may all hold copies of existing keys. Without knowing how many copies exist or where they are, a property is not truly secure, regardless of how good the existing locks appear.

A fresh lock installation on all external doors eliminates this risk entirely. In some cases, rekeying the existing locks (rather than replacing them) is a cost-effective alternative, provided the hardware is in good condition and of an appropriate security grade. A locksmith can assess the existing locks and advise whether replacement or rekeying is the smarter investment.

Should You Replace Your Lock or Just Rekey It? How to Decide

This is one of the most common questions asked, and the answer depends on a few practical factors:

• Replace the lock if the existing hardware is worn, damaged, of low quality, or does not meet current security standards. Replacing is also the right choice when upgrading to a restricted key system or a higher-grade deadbolt.
• Rekey the lock if the existing hardware is in good condition and of a reasonable security grade, but the key history is unknown. Rekeying changes the internal pin configuration so that old keys no longer work, while the lock body itself remains in place. This is a faster and more affordable option when the lock itself is sound.
• Combine both when moving into a property with a mix of newer and older locks. Some doors may benefit from rekeying while others need full replacement, and a locksmith can match all locks to a single key for convenience.

Lock Installation for Landlords and Property Managers: Tenant Turnover, Evictions, and Compliance

Landlords and property managers in Western Australia have specific obligations under the Residential Tenancies Act when it comes to locks and security. Rental properties must be fitted with locks that provide a reasonable level of security, and when a tenancy ends, it is standard practice to change or rekey the locks before a new tenant moves in.

For property managers overseeing multiple properties across Rockingham, Mandurah, and Kwinana, a reliable mobile locksmith is an essential part of the workflow. Master Lock Service works regularly with landlords and real estate agencies to handle:

• Tenant-turnover lock changes and rekeying between tenancies
• Eviction and repossession lock changes when a tenancy is terminated
• Compliance checks and lock upgrades to meet WA tenancy security requirements
• Master key system installations so property managers hold access without tenants having a master key

Operating Monday to Friday from 9am to 5pm, Master Lock Service can be booked in advance to align with settlement dates, inspection schedules, and tenancy end dates, keeping property management operations running smoothly.

Commercial Lock Installation for Businesses

Businesses have security needs that go well beyond a standard residential deadbolt. Commercial lock installation often involves master key systems, restricted key systems, and access control solutions that allow different staff members different levels of access across a building.

A master key system allows one key (held by management) to open all locks, while individual staff keys only open the areas relevant to their role. A restricted key system adds another layer by using patented key profiles that cannot be copied without authorisation, preventing unauthorised key duplication.

Master Lock Service designs and installs these systems for businesses across the Rockingham-Mandurah region, working with commercial premises, strata complexes, and industrial sites to create a logical, manageable key hierarchy from the ground up.

Security Door and Window Lock Installation: Including Jason Windows and Doors

Security screen doors and windows require specialist knowledge that goes beyond standard door lock fitting. The locks used on aluminium and steel security screens must be compatible with the specific door profile, and incorrect fitting can weaken the frame or void the screen door warranty.

Master Lock Service is a specialist in Jason Windows and Doors hardware, one of the most widely installed security door and window brands in Western Australia. This expertise means that when a Jason screen door lock needs replacement or a new lock is being fitted to a Jason window, the work is done with the correct tools, parts, and techniques specific to that brand. This is a niche area of locksmithing that many generalist locksmiths are not equipped to handle.

What Does Lock Installation Cost in Rockingham and Mandurah?

Lock installation pricing in the Rockingham-Mandurah area depends on several factors:

• Lock grade and type: A basic deadlatch costs less than a high-security restricted key deadbolt. The hardware itself is a significant part of the overall price.
• Supply and fit vs. fit only: Master Lock Service can supply and fit quality hardware, or fit a lock supplied by the customer. Customer-supplied hardware is accepted, though the locksmith cannot warranty the lock itself in that case, only the workmanship.
• Door preparation required: If a door needs new cutouts, additional drilling, or a reinforced strike plate, this adds to the labour time and cost.
• Number of locks: Installing multiple locks in one visit is more cost-effective than separate call-outs for each door.

For an accurate, no-surprise quote tailored to the specific property and requirements, contacting Master Lock Service directly is the best approach. Transparent pricing is a core part of how this family-owned business operates.

A straightforward single lock installation typically takes between 30 minutes and one hour. More complex jobs involving door preparation, multiple locks, or master key system setup will take longer. The locksmith can give a time estimate when booking.

Do locksmiths supply the lock or do I need to buy it myself?

Master Lock Service offers both options. The locksmith can supply and fit quality hardware, or fit a lock that the customer has already purchased. Supplying the lock through the locksmith ensures compatibility and often comes with a product warranty alongside the installation warranty.
