Depending upon the specific casement window the latch is mounted on the inside of the stationary side of the window/window frame. Some are riveted, some are secured by screws, if it is the later then you can remove the screws and loosen the latch (there may be several layers of paint, scratch away at the paint to see if it is either a screw/bolt head or a rivet.) See the links for a company, I like, for spare window parts.....
To fix a trunk latch that is stuck open, the teeth on the lock may have to be adjusted so the trunk will close. It is also possible that the cable for the trunk latch is broken. To fix the gas cap door latch may require a little bending and adjusting with a pair of pliers.
lift door handle, using screwdriver, move latch forward....will open
The back hatch will often not open if the internal mechanism or release has become damaged. Replacing the latch is the most effective and reliable fix.
When trunks get older, sometimes the latches get stuck. To fix them a person needs to add oil to the latch to loosen up the parts of the lock and turn the key hard.
pull the door handle on the outside and open the latch by hand both at the same time
Mine does that if the window is barley open!
Replace the door latch.
to open, use WD40...or a crowbar You will more than likely have to remove the inside door panel to get to the latch mechanism and find the problem of the latch does not work. No crowbar!!!!
Take it to a body shop. They have to open hoods when jammed in wrecks.
remove enter door panel. check the latch rod from handle to keeper spring latch (lock). either bent or detached. end.
While pulling on the handle as if to open the hatch, take a screw driver and pop the locking mechanism/latch to the open position. It should work no problem.
inside the trunk is an emergeny pull cord. when u turn the key there is a little piece on that cord that the key pulls on... u can only fix it with the trunk open though. so to open it get the remote or have a second person to open the trunk right after u press the botton. open it while the latch is rewinding
