Car doors won't open, locked out of my car

My ford mondeo 2001 won't unlock with the key, and not the trunk either. I locked the car without any problem, and can still turn the key to the right, but the key just stops when trying to unlock.

I did try to put a string between the door and roof, top reach the handle, but the door didn't open even though i managed to reach the handle? It seems very weird i think maybe the entire lock system is broken, or perhaps the handle was not entitely open(but i think it was).

Any suggestions on what to do? The remote key was lost years ago. I was thinking of discomnecting the battery, but i don't know if that will help…

This was my dads car until i got it last year, and he have experienced the same problem, however only during winter. So this has mot happened with such weather conditions as now (4C outside), i guess the car will open when then sun is out but that might take some days

1997 Ford Contour rear brake shoe adjustment?

I just recently replaced my rear brake shoes. Whenever I press my brake petal my back wheels continue to turn and I don't stop. My emergency/park brake does nothing as well. I need to adjust them but I haven't a clue how to.

Thanks, Travis.

Added (1). I read that they are self-adjusting on a few different sites now, however I tried backing up and stopping several times along with pulling the park brake up and down five or six times and I'm still able to push my pedal all the way to the floor without any braking being done.
