A door lock is subjected to cold rain and wind as part of its everyday operation. Dirt and water sneak into the lock causing the tumblers to corrode while the constant use of the lock wears on its internal parts. When this part fails the door can be jammed shut and unable to open or it will hinder the operation of the inner handle. How to handle this?

I suspect you have an issue not with the water getting into the door lock from the lock cylinder. I suspect you have water and dirt running down the window and getting into the door through the belt molding.

Then it gets into the lock cylinder from here so I would remove the interior door panel and see if you can find signs of water inside the door.

Here is a guide that will help with this:

We do not have a manual for this vehicle as it is not offered here in the USA, but we should be able to work through this. Just remove the door panel and let's get some pictures of the inside of the door and I am sure we can figure out the next steps.

I attached below what the belt molding is. Let us know what you find. Thanks
