looking for the slide bolt on and corner keys

I'm afraid I cannot identify what you have based on these photos. In order to help identify parts like these, we need to see them undamaged and fully removed from the frame. We also require clearly written dimensions. It's not possible to ID them otherwise.

As for how to remove, it should be a simple matter of pulling them out. Sometimes they can be stuck so it takes elbow grease. Depending on the frame, they may also be pinned in, which requires drilling to remove, but I cannot determine if that's the case for your window frame.

In the meantime, you can see our full selection here. Ultimately you may want to contact a local professional for assistance, since you aren't able to remove them.
