French Door Locks in North Brisbane
French doors are a pair, and a pair needs more thought than a single door. One leaf usually carries the handles while the other is held in place by bolts or a second locking point, and getting that arrangement right is what keeps the doors secure and the frame sound.

Start with the outcome
What kind of French doors do you have?
The construction of the doors decides what can be fitted. Timber, aluminium, uPVC and composite doors each take different hardware, and in every case the leaf that opens first does most of the work.
What this service helps you decide
Secure a pair of French doors without damaging the timber, glazing or finish.
Tell us what you need →What should I mention first?
Tell us the suburb, the door or access point involved, what has changed and the result you need. That gives us a useful starting point without asking you to diagnose the hardware.

What kind of French doors do you have?
The construction of the doors decides what can be fitted. Timber, aluminium, uPVC and composite doors each take different hardware, and in every case the leaf that opens first does most of the work.
The working leaf
The door with the handles does the locking
This leaf opens first and carries the main lock or lockset. It has to close against the frame squarely, or the latch will never line up reliably. Check whether it lifts, drops or rubs before assuming the lock is at fault, because a leaf out of square will wear out new hardware as quickly as old.
The outcomeThe main leaf closing and locking squarely.
The fixed leaf
The second door needs holding as well
The leaf without handles is secured by flush bolts, surface bolts or a lock into the frame or floor. When it is simply pushed shut, the pair is only as strong as that weakest point. Both leaves are reviewed together, because securing one and leaving the other loose gives a false sense of safety.
The outcomeBoth leaves secured, not just the door you use.
New or replaced doors
Hardware chosen before the doors are hung
New French doors can be prepared at the joinery stage for multipoint locking, a keypad or matched hardware on both leaves. Altering finished doors later means more cutting, more risk to the finish and fewer options. If the doors are not made yet, that is the right time to settle the locking.
The outcomeHardware prepared while the doors are being made.

What happens next
From the first question to the finished pair
- 01 / Step
Talk about the doors
Tell us the door material, roughly how old they are and whether the doors are part of a renovation. Mention any draughts, sticking or movement you have noticed, and whether the doors are used daily or only on some days.
- 02 / Step
Check both leaves
We look at how each leaf sits in the frame, whether the doors have dropped, and how the second leaf is currently held. Hinges, the sill and any gap between the leaves are part of the assessment.
- 03 / Step
Choose the locking
Multipoint locking, a lockset with separate bolts, or matched hardware on both leaves are all options depending on the doors. Discuss keys, how often the doors are used and how much of the original look you want to keep.
- 04 / Step
Test the pair
Both leaves are operated with the doors open and closed, and with the second leaf secured first, exactly as they will be used. Ask about the fit of the doors after the work, since French doors are sensitive to movement over time.
Useful guidance
Before the locks are fitted
Why a pair needs more than one lock
A single lock on the working leaf protects that leaf and nothing else. Because the doors are separate pieces hung on their own hinges, the fixed leaf can be released on its own unless it is held by bolts or a second lock. That is why the pair is treated as one system: the working leaf carries the main locking, the fixed leaf is bolted or locked in place, and both are checked to close against each other. Where only part of the arrangement is secured, the opening can be defeated through the other leaf.
Matching the lock to the door and the look
French doors are often a design feature, and the hardware does not have to spoil that. Where the doors are timber, hardware can be chosen in finishes that suit the existing handles and hinges. Where they are uPVC or aluminium, the doors usually have a specific profile that limits which units will fit properly. Glazing and the thickness of the stiles also matter, because a lock needs enough solid door to sit in. Bring along any existing key or product details if you have them, as that can narrow the options quickly.
Useful answers
French Door Locks questions.
If your situation is different, describe the property, door and outcome in the enquiry form.
Can French doors be locked if they have no lock now?
Usually yes, and it is a common job when older French doors were only ever held shut by friction or a simple bolt. The doors need enough solid material in the stiles to take the hardware, and both leaves have to be brought into the arrangement. The doors are checked first so the right type of lock is chosen.
Why do the two doors need different hardware?
They do different jobs. One leaf opens and closes every day and carries the main locking, while the other stays put and has to be held firmly against the frame or floor. Bolts or a second lock suit the fixed leaf, and trying to use the same hardware on both often leaves one side poorly secured.
Will fitting a lock damage my French doors?
Fitting hardware does mean cutting into the door, since a lock has to sit inside the timber or profile. The aim is to place it properly the first time, in sound parts of the door, with the frame and leaf prepared so nothing is forced. Where doors have started to move or have thin stiles, that is discussed before work begins.
Can a keypad or smart lock go on French doors?
Some entries suit electronic or keypad hardware, and others do not, depending on the door profile, the stiles and whether there is shelter from weather. Where it does suit the doors, the fixed leaf still needs to be secured separately. Tell us you are considering a keypad so it is factored into the assessment rather than added later.
What if there is a screen door or flyscreen in front?
A screen or security door in front changes the approach to the French doors and sometimes the hardware that will fit. Mention any second door at the same opening, along with its condition, because the two doors need to work together and a door that binds in front can wear the frame behind it.
