Lock Installation Melbourne
Installation is where the difference between a good lock and a good locksmith becomes obvious. The same deadbolt can feel solid and effortless, or gritty and unreliable, depending entirely on how accurately it was fitted.
A lock installation involves three things that all have to be right: hardware suited to the door, accurate preparation of the door and frame, and alignment tested with the door closed rather than swinging free.

What this usually involves
- Deadbolts and entry lock sets on timber doors
- Cylinder and mortice hardware, including existing-mortice replacements
- Sliding, stacker and screen door locks
- Window locks and keyed window hardware
- Commercial and glass door hardware
- Strike plate fitting and reinforcement
- Internal privacy and passage sets
- Keying new hardware to an existing key where compatible
Choosing hardware that suits the door
Before anything is drilled, the door needs assessing. Thickness determines what will physically fit. Material — solid timber, hollow core, aluminium framed, glass — determines what can be securely anchored. Existing preparation, especially a mortice pocket or old cylinder hole, often shapes the sensible options. Exposure matters too: a door taking western sun and rain needs finishes that will survive it.
This is why a lock bought purely on appearance sometimes cannot be fitted well. Hollow-core doors in particular have limited solid material to anchor into, and heavy hardware on a light door is a poor combination.
Why alignment matters more than most people expect
A bolt needs to enter its strike cleanly, without being pushed, lifted or leaned on. When alignment is even slightly out, every operation loads the mechanism sideways. That is what turns a new lock into a stiff lock within a year.
Melbourne conditions make this worse. Timber doors move seasonally, and a door fitted on a dry January afternoon can behave differently in a wet July. Allowing for that movement during installation is part of doing it properly.
- Bolt and strike aligned so the lock engages without force
- Strike plate fixed into structural framing, not just the jamb lining
- Correct backset and door thickness for the hardware chosen
- Operation tested with the door closed and latched
- Handle, cylinder and bolt all checked from both sides
Keying new hardware into your existing keys
Adding a lock does not have to mean adding a key. Where new hardware is compatible with your existing cylinders, it can often be keyed to match so one key still opens everything.
It is worth raising at the quoting stage rather than after installation, because it can influence which hardware is chosen.
When installation is the wrong recommendation
Sometimes new hardware is not the answer. If a door has dropped, a frame has swollen, or hinges have worn, fitting a new lock will not fix the symptom — the new lock simply inherits the same misalignment.
In those cases the door itself needs addressing first. Being told that plainly is more useful than being sold hardware that cannot solve the problem.
Questions about lock installation
- Can you install a lock I have already purchased?
- Usually yes, provided it suits the door thickness, material and existing preparation. It is worth checking the hardware details before the visit so no time is wasted.
- Can a new lock be keyed to match my current key?
- Often it can, where the new cylinder is compatible with your existing system. Mention it when you enquire so compatible hardware can be selected.
- Can locks be installed on aluminium and glass doors?
- Yes, using hardware designed for those doors. Aluminium and glass doors need purpose-made components rather than timber-door hardware.
- Will installing a deadbolt damage my door?
- A correctly executed installation is neat and properly prepared. On heritage or unusual doors, the approach is discussed with you first so you know exactly what will be done.
