These locks employ bayonet rods to lock, and they are able to easily seize up. The handle's nose is stuck in the popped-out state, and it is unable to return to the wedged lock position. This can be a difficult issue, but it can be resolved by following a few easy steps.
To fix the problem you must first take off the handle, which is easy enough using the help of a screwdriver. After removing the handle, you'll be able to see the screws that attach the lock to frame. Once the screws have been removed, you can make use of pliers or a wrench to try to grab the shoot bolts. If this is unsuccessful then you might need to insert the tool through the gap between the window and frame (the gap could be different at each end of the window) and create a "u" shape using your hands to attempt to grab the shoot bolts.
If you can manage to remove the bolts that shoot, then you can shut your window by adjusting the handle to the closed position. However, it won't be able to open again using the handle because the gearbox (espag or espagnolette) is likely to be damaged.

Once you've removed the hinges you can replace them with plywood boards cut to the correct size. The plywood should be thicker than the hinges that came with it to help support the weight when the window is closed and opened. Use wood filler to ensure that the hole left behind by the old hinge does not leak or become loose.
After you've filled in the holes and replaced the hinges, then you'll require painting the doors. Make sure you use a high-quality paint to ensure it lasts as long as possible. After the paint has dried and you are able to reattach the window. Secure any loose screws.
