A multipoint lock, often called a 3-point lock, secures a door at the top, middle and bottom when you lift the handle and turn the key. When the handle will not lift, the key will not turn, or the door will not lock, the cause is usually door alignment or a worn gearbox. We diagnose which it is and repair or replace the mechanism.
When to call us
- The handle will not lift, or lifts but the door does not lock.
- The key turns only when you push or pull the door hard.
- One of the bolts no longer engages.
- The handle is floppy or does not spring back.
How the job works
- We ask for photos of the door edge, handle and faceplate if possible.
- The technician checks alignment and keeps adjustments minimal.
- If the gearbox is worn, it is replaced with a compatible unit.
- Keeps and strikes are adjusted so all points engage smoothly.
- The door is tested repeatedly from inside and outside.
How a multipoint lock works and why it fails
When you lift the handle on a multipoint door, a gearbox inside the door edge drives rods that throw hooks or bolts at the top and bottom as well as the centre. Turning the key then locks the mechanism in place. Because several bolts must line up with several keeps at once, even a few millimetres of door movement can make the handle stiff or stop one bolt engaging.
Seasonal movement is the most common cause, and the right response is to adjust the keeps or hinges early. Forcing a stiff handle strains the gearbox, and a broken gearbox is the most expensive part of the system. When a gearbox has failed, we match a compatible replacement by measuring the backset, centres and faceplate, and we align the door so the new gearbox is not immediately overloaded.
What affects the price
The dispatcher explains the service call before anyone is sent, and the technician confirms the total with you before starting any work that adds cost. The main price drivers are:
- Whether alignment adjustment is enough or a gearbox is needed.
- Availability of the correct gearbox for your door brand.
- Door type: uPVC, fibreglass, aluminium or wood.
- Cylinder replacement if keys are also changing.
Hardware we see in Toronto
Multipoint systems from European and North American manufacturers are common on patio doors, French doors, and newer front doors, often with euro-profile cylinders.
Multipoint Lock Repair in Toronto: local context
Newer Toronto homes and renovated houses often have multipoint locks, and seasonal movement in the city's climate is the most common reason they stop engaging. Forcing the handle in winter can break the gearbox, so an early adjustment saves money.

What we will and won't do
Some gearboxes are proprietary to a door manufacturer. If a part is unavailable, we explain replacement options.
Frequently asked questions
Why does my multipoint lock only work if I push the door?
The door has moved out of alignment and the bolts bind on their keeps. Adjusting the keeps or hinges usually fixes it.
Can you replace just the gearbox?
Often, yes, with a compatible unit.
Should I force the handle if it is stiff?
No. Forcing it can break the gearbox. Call for an adjustment.
