When One Lock Controls Several Points
Multipoint locks (often called 3-point locks) are commonly found on modern glass patio doors, French doors, and European-style entry doors. When you lift the handle, multiple hooks or bolts engage along the entire height of the door frame, providing excellent security and weather sealing.
However, because these systems are mechanically complex and run the full length of the door, they are highly sensitive to door sagging and frame shifting. iProtect Locksmith provides expert multipoint lock repair across the GTA.
Multipoint Lock Services
- Door Realignment: Adjusting hinges to ensure the door sits perfectly square in the frame so the hooks engage the strike plates without friction.
- Gearbox Replacement: Replacing the central mechanism that connects the handle to the locking rods when internal gears shatter.
- Cylinder Replacement: Upgrading the Euro-profile key cylinders to high-security, anti-snap models.
- Hardware Sourcing: Identifying and replacing obsolete or broken handles, faceplates, and locking rods.
Do Not Force It
If you have to violently slam the door, lean your body weight against it, or use two hands to lift the handle to lock the door, stop. Forcing a stiff multipoint lock will eventually snap the internal metal gears, resulting in a door that is permanently jammed shut. Call us for an alignment before the hardware breaks completely.
Frequently Asked Questions
Why is the handle on my multipoint door so hard to lift up?
You have to lift the handle to engage the locking points along the frame. If it's hard to lift, the door has usually sagged on its hinges, meaning the hooks are hitting the metal strike plates instead of sliding into the holes. Do not force it; the door needs realignment.
The handle spins freely and the door won't open. Can you fix it?
Yes, a freely spinning handle usually means the internal gearbox (the central cassette) has shattered. We can extract the broken gearbox, open the door, and replace the broken mechanism.
Do you carry replacement parts for European-style doors?
Multipoint locks come in hundreds of variations (GU, Hoppe, Ferco, Winkhaus). We carry common replacements and can source specific gearboxes based on the measurements of your door's hardware.
