I have a 2002 kia rio with manual locks. My driver's side door is stuck shut. I also had this problem with my rear passenger door due to the latch screws coming loose. I now tighten the screws and lubricate the latches regularly. Unfortunately when I was attempting to get the driver's door open I used a pair visegrips to pull up on the lock pin and I broke it. I ordered a new latch/lock pin assembly $52 from kia and new scews $?. I will be climbing through the passenger side until all the parts arrive. I appreciate everyone previous experience with this problem. I will be able to use your advise to get the door open when the time comes!
