Lock installation, repair and replacement in Montreal
A lock that sticks, a key that is hard to turn or a new door to fit: Lafleur assesses whether to repair, rekey or replace, then schedules the service call in Montreal or on the North Shore. Pricing is explained before the work starts.
Mon–Fri, 8 AM to 5 PM. We reply to requests during these hours.

What we do
- Install a lock, deadbolt or handle on a new or existing door.
- Repair a lock that sticks, jams or has a key that is hard to turn.
- Replace a worn or broken lock, or one whose part is no longer available.
- Rekey a lock without replacing the whole mechanism, when possible.
- High security : advice and products from Mul-T-Lock, Medeco, Abloy and ASSA, plus older or discontinued parts that are hard to find.
Residential
Houses, condos and plexes: locks and deadbolts on front or back doors.
Commercial and buildings
Shops, offices, rental buildings and condo associations: multiple doors, master keys and shared access.
Repair or replace?
We don’t replace for the sake of replacing. The choice depends on the condition of the mechanism, the door and the parts available. Lafleur explains the options, and pricing is explained before the work starts.
Often repairable
- The key catches, sticks or is hard to turn
- The latch sticks or the door doesn’t close properly
- A worn part is still available
- You simply want new keys
Usually better replaced
- The mechanism is broken
- The part is no longer available
- The door is new or has been changed
- You want a higher level of security
