Lock change in Montreal: what to know

When a lock should be changed

After keys are lost or stolen, when moving into a place whose key history you don't know, after a roommate or tenant leaves, or when the key starts catching and needs force. A lock that gets stiff is usually warning you.

Cylinder or whole lock?

If the lock body is sound, replacing the cylinder is enough — old keys stop working immediately. If the mechanism is worn, misaligned or low quality, a full replacement lasts longer.

Several doors, one key

Front door, back door, shed and garage door can share one key when the cylinders are compatible. Ask on the call so the right hardware comes along.
