The Key Keeps Turning in My Lock – What Should I Do?

If your key keeps turning in the lock without engaging the mechanism, you may have a faulty lock. Here’s what might be causing it and how to fix it.

Possible Causes:

• Broken Lock Cylinder – The internal components may be damaged or misaligned.
• Worn-Out Lock – Over time, locks deteriorate due to frequent use.
• Detached Cam or Tailpiece – The connection inside the lock may be loose or broken.
• Key Damage – A bent or worn-out key might not engage the mechanism correctly.

What You Can Do:

• Try Another Key: If you have a spare, test it in the lock to rule out key damage.
• Lubricate the Lock: Spray a silicone-based lubricant inside the keyhole to improve movement.
• Check for Loose Screws: If the lock feels wobbly, tighten the screws on the door plate.
• Call a Professional: If the issue persists, a locksmith can repair or replace the lock to restore security.
