Make sure you spray the entire interior of the lock and the cylinder, including the latch switch, to ensure that it's clean and free of any obstructions.

Next, make sure that the lock's cylinder is lubricated with an oil-based lubricant that is dry, such as graphite powder or commercial car door lock lubricant.

Move the Latch

If you use the outside or inside car door handle, the mechanism extends metal rods (or other linkage) that release the latch from its anchor. These are usually connected to plastic fasteners which bind them together using specialized adhesives. Your car could get stuck in open position if an iron rod is removed from its fastener, or if the fasteners are broken.

A professional locksmith for automotive can inspect the inner door lock assembly for such problems and can reattach rods that are disconnected. They also have the tools needed to take off the door's interior and open the latch assembly without damaging it. Most people won't wish to tackle this task by themselves, particularly if they are running late to work or have other obligations.

Another reason why your car doors could become stuck is that the internal latch release cable has been disconnected from its actuator. This can happen if the lock has been damaged or when the door or its parts have been damaged due to an accident or by a strong slam.

This problem can be resolved by connecting the rod with its actuator using an screwdriver, then turning it in a clockwise direction. This will enable the latch to be placed properly and will allow you to open the door by hand from the inside or outside.

This kind of problem is caused by wear and tear of the bushings connecting rods that move all these components. As they wear, it is easy to build up slop in between them that causes the mechanism to move and it won't latch correctly. You can test this by pulling on the inner and outer handles separately while watching the other moving parts for movement.
