11 Step-by-step Guides on How to Fix a Broken Lock on Door

Step 1: Clean the Lock

The first step to fixing a broken lock on your door is to clean it thoroughly. Use a cleaning solution or rubbing alcohol to clean the lock and all its components. This will help remove any dirt, debris, or rust that may be causing the lock to malfunction. You can use a toothbrush to reach difficult areas. But, make sure to wipe down the lock and let it dry completely before proceeding to the next step.

Step 2: Apply Lubricant

After cleaning the lock, apply lubricant to all moving parts. This will help loosen up any stuck or rusted components and make it easier to turn the key. You can use WD-40, graphite powder, or any other lubricant you have on hand. Be sure to apply only a small amount of lubricant as an excessive amount can attract dirt particles, leading to further issues. Once applied, try turning the key to see if it’s working. If not, move on to the next step.

Step 3: Tighten Loose Screws

Check for any loose screws and tighten them using a screwdriver. A lock that is held together by loose screws can easily malfunction and prevent the key from turning correctly. Make sure all screws are securely tightened and try turning the key again. It should work perfectly fine now. Otherwise, proceed to the next step.

Step 4: Check for Broken or Bent Key

Inspect your key to see if it’s bent, broken, or damaged in any way. A bent or broken key can prevent the lock from working correctly. If this is the case, you will need a replacement key or a copy made from an undamaged one. You can also try straightening out a bent key using pliers. It is essential to have a spare key in case of any emergencies.

Step 5: Use a Hammer

If your lock is not turning, you may need to apply some force. Use a hammer to gently tap the key into the lock. This should help loosen any stuck pins or debris, allowing the key to turn freely. You can also try tapping the lock itself to loosen up any stuck parts. However, be cautious not to hit too hard as it can cause further damage.

Use a Hammer to Gently

Step 6: Try Another Key

If the key is not turning in the lock, try using a different key. Sometimes, keys can wear out over time due to extensive use. Using another key could make all the difference and avoid having to do a full-on repair. This is especially true if you have multiple keys for the same lock. You can also try using a spare key or getting a copy made.

Step 7: Check the Strike Plate

The strike plate is the metal piece attached to the door frame that catches the latch when you close the door. If it’s not aligned correctly, it can prevent the lock from functioning properly. Use a screwdriver to loosen and reposition the strike plate so that it’s in line with the latch. This will help ensure that the lock functions smoothly. But, if the strike plate is damaged or cracked, it will need to be replaced.

Step 8: Clear Any Obstructions

Sometimes, debris or foreign objects can get stuck inside the lock, preventing it from working correctly. Use a toothpick or paperclip to remove any obstructions from the keyhole and try turning the key again. This should fix the issue if that was the cause of the problem. However, if the lock still won’t budge, proceed to the next step.

Step 9: Take Apart the Lock

If none of the above methods work, you may need to take apart the lock for a more thorough inspection. Use a screwdriver to remove any screws and separate all parts of the lock. Pay close attention to any broken or worn-out components that may need to be replaced. You can take a picture or make a note of the parts’ positions for easy reassembly. You can also refer to the lock’s manual if you have it for guidance.

Step 10: Replace Worn-out Part

If you find any broken or worn-out parts, replace them with new ones. You can purchase replacement parts from a hardware store or online. Make sure to buy parts that are compatible with your lock’s make and model.

Once replaced, reassemble the lock and try turning the key again. But, if the lock still won’t turn, you may need to replace the entire lock. This is a last resort, but it’s better to have a fully functional lock than one that doesn’t work correctly.

Step 11: Seek Professional Help

Plus, they can also provide you with helpful tips on how to maintain your locks for long-lasting functionality. Always remember to keep their number handy in case of any future lock-related issues.
