Locks keep your home, office, and car secure. But when they don’t work as expected, frustration quickly follows. Before calling for a lock repair service, try these simple lock troubleshooting tips. You might fix the problem yourself and save money.

Top Lock Troubleshooting Tips

1. Key Won’t Turn in the Lock

This is a common issue with both house and car locks. If your key doesn’t turn, follow these steps:

  • Check if the key is correct.Double-check you’re using the right key.
  • Lubricate the lock.A sticky lock may need lubrication. Use a graphite spray or silicone-based lubricant. Avoid oil-based solutions like WD-40, as they attract dust.
  • Jiggle the key.Gently move it up and down while turning.
  • Inspect the key.If it’s bent, try straightening it carefully with pliers.
  • Check for dirt inside.Use compressed air to clear any debris.

If none of these work, you may need a lock repair service.

2. Lock is Sticking or Hard to Turn

When a lock becomes stiff, it could be due to dirt buildup or internal misalignment. Here’s what you can do:

  • Clean the lock.Insert a cotton swab or use a small brush to remove dust.
  • Apply lubricant.Use a dry lubricant like graphite powder to keep it smooth.
  • Check the door alignment.If the lock doesn’t line up with the strike plate, adjust the door hinges.

If your lock still sticks, it might be time to call a professional locksmith service.

3. Key Breaks Inside the Lock

A broken key can leave you locked out of your home, office, or car. Here’s what to do:

  • Use needle-nose pliers.If part of the key sticks out, gently pull it out.
  • Try a key extractor tool.These are available at hardware stores.
  • Use a strong magnet.In some cases, a powerful magnet can pull the key fragment out.
  • Lubricate before extraction.A little graphite powder can help ease the removal.

If the key is fully lodged inside, you’ll need an emergency lockout service.

4. Lock Cylinder Turns But Won’t Unlock

If the key turns, but the door doesn’t open, the lock cylinder may be loose. Try these solutions:

  • Tighten the set screws.Remove the lock cover and check for loose screws inside.
  • Align the lock mechanism.If parts inside shift out of place, reposition them.
  • Check the latch or bolt.It may be stuck and need lubrication.

5. Car Door Won’t Unlock

Car locks can fail due to worn keys, electrical issues, or frozen locks. Here’s how to troubleshoot:

  • Try a spare key:If one key doesn’t work, another may.
  • Check the battery in the key fob: A dead battery can prevent unlocking.
  • Use de-icer on frozen locks: If it’s cold outside, moisture inside the lock may have frozen.
  • Manually unlock the door: If it’s a power lock issue, use the physical key instead of the remote.

If you’re still locked out, a car unlock service can get you back in.
