5 Signs Your Locks Need to Be Replaced

Your door locks are your first line of defense against intruders. But like any mechanical device, locks wear out over time. The problem? Most people don't notice until it's too late—either they're locked out, or worse, someone has broken in. Here are five clear signs your locks need attention.

1 Your Key Sticks or Is Hard to Turn

If you're wrestling with your key every time you lock or unlock the door, something's wrong. While this can sometimes be fixed with lubrication (use graphite, not WD-40), persistent sticking often means:

  • Internal pins are worn or damaged
  • The lock cylinder is misaligned
  • The lock mechanism is corroded

The risk: A sticking lock is a weak lock. It may fail at the worst moment or be easier to pick.

2 Visible Rust or Corrosion

Canadian winters are harsh on exterior locks. Salt, moisture, and freeze-thaw cycles cause metal to corrode. Look for:

  • Orange or brown discoloration
  • Flaking or pitting on the lock surface
  • Crusty buildup around the keyhole

The risk: Rust weakens metal components. A corroded lock is significantly easier to force open.

3 The Lock Is Loose or Wobbly

If your deadbolt or door handle feels loose, wiggles when you turn the key, or the faceplate is pulling away from the door, the lock's integrity is compromised.

Common causes:

  • Worn mounting screws (easily fixed)
  • Damaged lock housing (needs replacement)
  • Door frame deterioration (bigger problem)

The risk: A loose lock can be kicked in much more easily than a properly secured one.

4 You've Had a Break-In or Attempted Break-In

Even if a burglar didn't get in, they may have damaged your lock in the attempt. Signs include:

  • Scratch marks around the keyhole (picking attempt)
  • Bent or damaged strike plate
  • Lock that suddenly feels "different" to operate
  • Door that doesn't quite close right anymore

The risk: A tampered lock is a weakened lock. Replace it immediately, even if it seems to work.

5 Your Lock Is Old or Outdated

Lock technology has improved significantly. If your locks are more than 10-15 years old, they likely lack modern security features:

  • No bump resistance: Pre-2007 locks are often vulnerable to bump keys
  • No pick resistance: Standard pins vs. security pins
  • Low grade rating: Older locks may be Grade 3 (lowest security)

The risk: Modern burglars have access to techniques that defeat old locks in seconds.

🚨 Urgent Replacement Needed

Replace your locks immediately if:

  • You've lost your keys and don't know where they are
  • Someone untrustworthy has (or had) a copy
  • You've experienced a break-in or attempted break-in
  • You can visibly see damage to the lock

How Long Do Door Locks Last?

With proper care, quality door locks can last:

Environmental factors matter too. Locks exposed to direct weather, salt spray, or extreme temperatures wear faster.
