  1. A Phillips head screwdriver.

10 Easy Steps on How to Fix a Window That Won’t Lock

Step 1. Inspect the Window Latch:

First, take a look at the window latch to see if it is misaligned or broken. If the latch is damaged or not aligned correctly, it could be preventing your window from locking properly. As a result, the window won’t close tightly.

Step 2. Re-align or Replace the Latch:

If the latch is misaligned, try realigning it as best you can with a screwdriver. However, if the latch is too severely damaged and cannot be realigned, you may need to replace it with a new one. Try a hardware store or online retailer for replacement parts.

Step 3. Check for Warped Window Sills:

Take a look at the window sill and check for any warping that could prevent your window from closing tightly enough to lock securely. You can check by putting your hands on either side of the window sill and pushing inwards to see if one side is warped. Don’t worry if you find a warped window sill; the next few steps will help you correct this.

Step 4. Make Adjustments to the Window Frame:

If the window sill is warped, try adjusting the window frame by unscrewing a few screws on either side of the window. This should help put it back into alignment and secure it when you screw it back together. Don’t forget to use your lubricant or WD40 on any rusty screws.

Step 5. Apply Lubricant:

Once your window frame is adjusted correctly, lubricate any moving parts of the latch or lock with some WD40 or other suitable lubricant. This will help ensure all components work smoothly and move freely, allowing you to shut your window properly. Ensure that you don’t use too much lubricant, as this could make the window difficult to open.

Step 6. Check for Obstructions:

Make sure no obstructions are blocking the path of your window as it closes – this could be causing it not to close correctly or lock properly. Look for any items in the way and remove them. If necessary, use a rubber mallet or hammer to make adjustments.

Step 7. Insert Sawdust Into Window Sill:

If you’re still having trouble with your window, try inserting some sawdust or wood shavings into the window sill. This can help fill any gaps between the sill and frame that could prevent your window from closing tightly enough to lock securely. Additionally, this can help with any warping or misalignment that may be causing your window to not lock properly.

Step 8. Hammer It Shut:

Once you have filled any gap with sawdust, use a rubber mallet or hammer to tap the edges of your window shut until they are tight against each other- this should provide some extra security when locking it shut! Be careful not to hit too hard, as this could cause damage.

Step 9. Replace Broken Lock Parts:

If you still have trouble locking your window, replace any broken or damaged lock parts. Try a hardware store or online retailer for replacement parts. You can also try fixing broken parts with a glue gun or other adhesive.

Step 10. Test and Secure:

Once all the steps above are completed, test your window by opening and closing it several times to ensure the latch is properly engaging and locking securely when closed. If everything is working okay, add extra security to your window by adding additional locks or latches if necessary. Remember to check your windows regularly and ensure that they are properly locked!

By following these easy steps, you should be able to successfully repair any window that won’t lock and ensure the security of your home is not compromised! Remember to regularly check your windows for any signs of wear or damage so that you can stay on top of any repair needs.

5 Additional Tips and Tricks

1. Check the locking mechanism of your window. If the latch is stuck, you may need to use a flathead screwdriver (or similar) to pry it apart and free up the lock gently.

2. Inspect the window frame for any signs of warping or damage, such as loose screws or splits in the wood. Loose screws can be tightened with a screwdriver, while split wood needs to be repaired with glue and filler before trying to re-lock the window.

3. Clean out debris that may have gotten caught in or around the lock by using a vacuum cleaner hose attachment or compressed air to blow it away.

4. Test if there is too much tension on the lock by lifting up on the sash itself, if the window won’t stay shut no matter how hard you lock it then there is too much tension and needs to be loosened.

5. Is the weather causing your window problems? If you live in a region that experiences extreme temperatures, adjust the hinges of your windows to better cope with temperature changes; this will prevent them from becoming jammed or warped by expanding or contracting too much.

By following the steps above and adhering to these additional tips, you should be able to successfully fix any window that won’t lock and enjoy the peace of mind that comes with knowing your windows are secure.

5 Things You Should Avoid

  1. Don’t try to force the window open or closed if it won’t move easily – this could further damage the latch or cause other issues.
  2. Avoid using a screwdriver to pry apart any locks, as this can also cause damage to the mechanism and make them less secure.
  3. Don’t use too much lubricant on any components, as this could stop them from functioning properly.
  4. Never hang anything on your window that would block its movement or prevent it from closing when locked; this will reduce its security levels significantly!
  5. Try not to over-tighten screws or other parts when adjusting your windows, as this could cause warping or breakage of the frame.

By following these steps and avoiding these potential pitfalls, you should be able to easily fix any window that won’t lock and ensure the security of your home.

Does the Window Need Replacing?

If your window still doesn’t lock after following the steps above, consider replacing it.
