It's still the best method to ensure that your car's door is able to be opened using one key.
Moving the Latch
Whenever you operate the inside or outside door handle of your vehicle the mechanism extends rods (or other linkages) that release the latch from its anchor. They are usually connected to plastic fasteners, which are bonded by special adhesives. Your car may become stuck in open position if a metal rod is detached from its fastener, or if the fasteners have been damaged.
A professional locksmith can check the door's internal lock assembly for any issues and reattach any disconnected rods. They also have the tools to remove the interior door panel and access the latch assembly without causing damage to it. This is a job that the majority of people would not wish to tackle on their own particularly on a day when they're late for work or other obligations.
Another reason why your car doors may become stuck is that the internal latch release cable has been disconnected from its actuator. This can happen if the lock has been jimmied or if the door's parts have been damaged as a result of an accident or a violent hit.
This issue can be solved by connecting the rod of the actuator to its actuator with an screwdriver, then turning it in a clockwise direction. This will move the latch into its proper position and allow the door to be opened manually from either inside or out.
This type of malfunction is usually caused by excessive wear to the bushings that connect the rods that move all these components. If they're worn out, it is easy to get slop between them that makes the whole mechanism move and not latch or lock correctly. You can check this by pulling both the handles that are on the outer and inner sides while observing any movement in these moving parts.
