How to Fix a Car Door Latch That Won't Spring Back?

Use a flathead screwdriver, place it in the flat groove and tap it with a hammer. This is done to loosen the threads. Align the screw, then strike the screwdriver with a hammer. On one hand, this ensures the screwdriver fits snugly into the screw head; on the other hand, the impact will loosen the rounded screw, making it easier to turn. On the rounded part, use a hard knife to carve a cross or straight line shape. A straight line is simpler—carve it deep, then use a flathead screwdriver to remove it. Reverse the use of a small drill bit to first drill a hole into the rounded screw, then screw in a reverse-threaded tap to create internal threads.
I've also encountered the issue of door latch not retracting frequently as a veteran car owner. The first step I recommend is to check if the latch is rusted or jammed with debris. I would first turn off the engine for safety, then use a slender tool to gently probe the latch area—clearing out any dust or small stones if present. Next, apply some lubricant like WD-40 or regular engine oil, wait a few minutes after spraying, and repeatedly open/close the door several times to encourage retraction. If it still doesn't move, the internal spring or components may be deformed. I'd disassemble it myself for cleaning, sand down rust spots with sandpaper, then reassemble and test. If unresolved, it's best not to force it and seek professional repair at a certified garage to avoid further damage to the locking system. For routine maintenance, I spray lubricant on door latches every few months as preventive care to avoid hassle.
