Doors hard to open

The passenger door has been difficult to open from the outside for a long time now. Sometimes it would only open if you pushed against the door.

But it wouldn't open at all the other day, and the driver's door was also becoming a little difficult to open so I thought I better do something about it before I couldn't get into my car at all.

I did a bit of research and I thought I had a broken outside door handle but then I came across a YouTube video where some guy found that his problem was caused by the door latch and just needed some care, rather than replacement parts.

I tried some WD40 in my passenger door latch and it started showing some signs of improvement. After a bit of time and a lot of WD40 it was opening like new!

I did the same on the driver's side and watched as it slowly started freeing up.

WD40 send to work well, although I don't know how long for. I sprayed from all angles and used a screwdriver to push the locking parts in and then operated the door handles repeatedly to work the fluid into the mechanism.
