How to fix lock jam on fly screen?

[Ivy119]

When it’s really hot, the silver lock levers get stuck and I’m not able to open the door.

Due to the recent heat, it looks like it’s now stuck for good and I’m unable to unlock the levers. Please note that I also don’t have the key for this door. Is there any way to get it open?

Thank you.

Hi @Ivy119,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

When locks like this jam, it is often because dirt, grit or other small particles have gotten inside the mechanism.

My suggestion is to remove the screws and take the handle out of the door, give it a clean with some WD40 and a cloth, then apply a silicone lubricant such as this WD-40 Specialist High Performance Silicone to the moving parts of the lock.

After this, operate the lock a few times outside of the door to test it and ensure the lubricant is getting into the correct areas before reinstalling.

Let me know what you think and if you have further questions, please don't hesitate to ask.

Hi Jacob

Thank you for your speedy response.

 

The lock is jammed while the door is closed. I removed the screw to try taking off the handle, but noticed the bottom part (lever & key lock) won’t budge, so I can’t fully remove it.

Any suggestions on what I should do?

Thank you

Hi @Ivy119,

Can you access the other side of the door? 

There should be another screw going through the bottom of the handle, which may be accessible from the opposite side of the door.

If you can remove that screw, you should be able to remove everything else.

Let me know what you find.

Great suggestion! 
so I went to the otherside of the door and able to unscrew and pull out the handle.

As marked in the picture, thats the hole of the levers that’s jam. I have sprayed D40 and push the lever again, however its still doesnt budge..

Any suggestion what else I need to do?

Thank you.
