Signs of Lock Failure | Expert Locksmith Tips for Sunshine Coast Residents

When most people think about broken locks, they imagine a door that won’t open or a key that snaps. But lock failure rarely happens overnight — in fact, your locks might already be giving you warning signs that you’re ignoring.

As experienced locksmiths on the Sunshine Coast, we’ve seen hundreds of lockouts and security issues that could have been avoided. In this post, we’re revealing the quiet signs that your lock is failing — and what you can do before you’re stuck outside at 10pm on a rainy night.

1. The “Wiggle”

If your key needs a little jiggle to work, that’s not just wear and tear — it’s a warning. This often means the internal pins are misaligned or your key is worn. You might still be getting in… for now.

Fix it early: Rekeying or replacing the cylinder is a simple, affordable fix — especially compared to a midnight emergency callout.

2. Slow Turns or Sticky Keys

If your key doesn’t turn smoothly, or you need to backtrack slightly before it works, the lock’s mechanism is likely full of dirt, rust, or degrading components. Spray lubricants might give temporary relief, but this is often just masking a bigger problem.

3. Deadbolt Doesn't Sit Flush

A deadbolt should slide in effortlessly when your door is closed. If you need to push or pull the door slightly, your lock and door frame are out of alignment — often due to foundation shifts or door swelling.

Why it matters: Forced alignment wears out both the lock and the bolt housing, making the lock easier to pick or bypass.

4. Your Lock Looks… Fine?

Many older locks still “work,” but aren’t up to modern security standards. If your lock is more than 10 years old, there’s a good chance it’s vulnerable to techniques like bumping or snapping. Criminals know how to spot these.
