PVC Glass Fading

Hello, I went to install the window screens at our new house. They are Anderson windows and look like the original windows (1985). The window screens have spring loaded posts that you pull and insert into a clip (not sure what else to call it) on the screen frame. The problem is on many of our windows, the clip is missing and the only thing remaining is a hole (1/2") where the clip should go. This hole itself is too big for the post. Does anyone know the actual name of the part the post goes into and where I could order some? I've been to two hardware stores and they don't sell them. I also couldn't find them on Anderson's web site. Thanks for your help!

We refinished our front door and while installing the "button stops" were pushed in such a way that the front door is now locked, inside and out. How can I disable this feature and gain entry? We have no keys for this lock.
