Removing old part

A home owner from Michigan says:
I have my new 90-115 keeper, but I am having difficulty removing the old part. It looks like it should just slide straight up after removing the screws, but it's stuck. Any tips on how to loosen it?
A home owner from Michigan says:
Never mind - I squirt some 3-in-1 oil everywhere I could, and after much wriggling it finally came out. One down, four to go!
A home owner from Michigan says:
OK, my first problem pales in comparison to my new one. The keepers on the bathroom window had rusted (which allowed the burglars to break them,which is why I ordered replacements.) Unfortunately, the keepers broke inside the window. I can get the top part out, but the bottom, below the holes, is still inside. I think I may need a different kind of lock. Any suggestions?

Thanks for posting! I'd be happy to help you figure out how to remove those keepers. Can I see some pictures of the bathroom window where the broken keeper us? That will help us come up with a solution.
