Window Locks

We've purchased a home built in 1985 that has Anderson casement windows. Most of the windows are tall and long with the hinge mounted on one side, a crank at the bottom, and a locking mechanism built into the window frame on the other. There are also three small casement windows in the house that do not have window locks on them, and we want to install those now. If you provide me with an email address, I can send pictures of the windows to help in identifying the best locks to install. In the pics, you'll see that the small casement windows we're talking about are the three bottom panes on a large wall of windows. The small windows open by crank along a hinge at the top with swing arms pushing out the window from the bottom. As you'll see, the window frames are wood. The wood frame depth is about 2", although as you'll also see, it's not a flat surface, but rather is beveled. The metal frame around the glass is about 3/4" deep. Hope that gives you enough information.

Thanks for any help you can offer, and let me know if you need additional information.
