Locks are the first line of defense in any home, and when they stop working properly, it’s not just a minor inconvenience—it’s a serious security concern. In Montreal-Nord, where extreme weather, aging homes, and urban living intersect, residents face unique lock challenges year-round.
Whether you’re dealing with frozen locks in the dead of winter or a key that just won’t turn, understanding these common issues—and knowing how to fix them—can save you stress, time, and money. Below are the top 5 lock problems we frequently see in Montreal-Nord homes and expert tips on how to resolve them.
1. Frozen Locks During Montreal Winters
What’s the issue?
Montreal’s long, icy winters often cause locks to freeze due to trapped moisture inside the mechanism. This is especially common in older locks or those exposed to outdoor elements.
Signs You Have This Problem:
- Key won’t insert or turn.
- Lock feels completely stuck or icy.
How to Fix It:
- Use a lock de-icer: Available at most hardware stores, de-icers can thaw internal components quickly.
- Try warming your key: Carefully heat your key with a lighter (without burning yourself) and insert it slowly to melt the ice.
- Prevent it: Spray graphite lubricant in your locks in late fall to reduce moisture buildup.
When to Call a Locksmith:
If the lock is frozen solid and home remedies don’t work—or if the key breaks inside—it’s best to call a professional locksmith in Montreal-Nord for safe, damage-free assistance.
2. Misaligned Door Latches
What’s the issue?
Shifting door frames due to weather changes or poor installation can lead to misaligned latches. This prevents the lock from fully engaging or disengaging.
Signs You Have This Problem:
- Door doesn’t latch unless you force it.
- You hear scraping or feel resistance when closing.
How to Fix It:
- DIY Fix: Tighten hinge screws or slightly reposition the strike plate using a screwdriver.
- Advanced Fix: Use wood filler and redrill holes to realign the latch.
When to Call a Locksmith:
If the issue persists or affects multiple doors, a locksmith can properly realign your door frame and ensure your locks are functioning smoothly.
3. Worn Out or Rusty Lock Mechanisms
What’s the issue?
Over time, lock mechanisms wear down—especially in the humid summers and salty winters of Montreal-Nord. Rust and internal wear can make locks unreliable.
Signs You Have This Problem:
- Lock sticks or grinds when turning.
- You need to jiggle the key to open the door.
- Key doesn’t go in smoothly.
How to Fix It:
- Use lubricant: Apply a silicone- or graphite-based lubricant (never WD-40) to loosen internal parts.
- Consider replacement: If the lock is visibly rusted or more than 10 years old, replacing it may be safer.
When to Call a Locksmith:
A professional can clean and recondition the lock or install a new one with better resistance to Montreal’s weather conditions.

4. Broken Keys Inside the Lock
What’s the issue?
Keys naturally wear down with time, and in colder weather, they’re more prone to snapping—especially if you’re rushing or using excess force.
Signs You Have This Problem:
- Half of your key is stuck inside the lock.
- You can’t turn the lock at all.
How to Fix It:
- Attempt gentle removal: Use needle-nose pliers or a broken key extractor (available at hardware stores).
- Avoid inserting tools randomly: This can push the key further in and damage the lock.
When to Call a Locksmith:
If the key is deeply embedded or you’re unsure what to do, a locksmith can safely extract it and make a new key on the spot.
5. Lock Cylinder Turns But Doesn’t Unlock
What’s the issue?
This problem often points to internal lock failure or a loose set screw. The cylinder may spin freely, but the door remains locked.
Signs You Have This Problem:
- Key turns normally, but nothing happens.
- Lock feels “too loose” or spins endlessly.
How to Fix It:
- Tighten set screws: If you can remove the faceplate, check for loose screws and tighten them.
- Replace the cylinder: If parts inside the lock are broken, the cylinder might need replacing.
When to Call a Locksmith:
Don’t risk being locked out—this issue typically requires disassembly and professional realignment or replacement.
Bonus Tip: When to Repair vs. Replace Your Lock
It’s tempting to keep repairing an old lock, but sometimes replacement is more cost-effective and secure. Here’s a quick rule of thumb:
- Repair if: The lock is relatively new, the damage is minor, and the mechanism is still reliable.
- Replace if: The lock is over 10 years old, consistently malfunctions, or lacks modern security features.
Modern locks offer better resistance against bumping, picking, and weather damage—essential for homeowners in Montreal-Nord.
Final Thoughts
Your home’s security shouldn’t be compromised by something as fixable as a faulty lock. By addressing these common lock issues early, you can avoid bigger headaches—and even prevent break-ins. From frozen locks to misaligned latches, there are practical solutions you can try on your own, but never hesitate to call in a professional when needed.
