5 Signs It’s Time to Replace Your Door Locks

Your door locks are your first line of defence. But like anything else in your home, locks wear out over time or become outdated. Ignoring the signs of a failing lock can leave you vulnerable to break-ins, lockouts, or costly emergencies.

At Jarrah Locksmith, we often get called out to fix issues that could’ve been avoided with a timely lock replacement. Here are the top five signs it’s time to upgrade your locks.

1. Your Lock Feels Loose or Wobbly
If your lock jiggles or doesn’t feel secure when you turn the key, that’s a clear red flag. Loose locks are easier to tamper with and may eventually stop working altogether. This is especially common on older doors or locks that haven’t been serviced in years.

2. It’s Getting Harder to Turn the Key
Is your key sticking, jamming, or requiring extra force to turn? That’s a sign your lock cylinder may be worn, misaligned, or internally damaged. Don't wait until the key snaps or you get stuck outside — a smooth-turning lock is essential for daily use and emergency situations.

3. You’ve Just Moved or Lost a Key
Even if the locks seem fine, you should replace or rekey them after moving house or losing a key. You never know who might have access to the old ones — real estate agents, tradies, or previous tenants. A fresh lock or rekey offers peace of mind and full control over who can enter your home.

4. Your Locks Are Outdated or Don’t Match Modern Security Standards
Technology and break-in techniques have evolved. If your locks are more than 10 years old or aren’t compliant with today’s standards, you could be at risk. Upgrading to modern deadbolts, digital locks, or high-security cylinders ensures your home is as secure as possible.

5. You've Had a Break-In or Attempted Break-In
If someone has forced your lock or tried to tamper with it, it may no longer be structurally sound. Even if it still "works," the internal mechanism could be compromised. Replacing it immediately helps restore your security and your peace of mind.

Bonus Tip: Don't Wait for a Complete Failure
Often, people wait until a lock completely fails to call a locksmith. But preventative maintenance and timely upgrades are far cheaper — and far less stressful — than dealing with emergencies.
