Here is a update..i thought the same thing as you did ,but i just took off the passenger side actuator and tried the key and all works fine once the acctuator is off there. So i installed the new one and once i did that it went back to the same thing where the key will not turn. I just dont get it ...it has a new accuator that works fine but now it seams to hard to turn the key like the accuator is to hard to move up and down with the key. Just a note the ones i installed are not factory ford they are form late model restoration i just bought the kit. Man its pissing me off. Brand new accuators and she still wont be able to lock the doors..unless she wants to open the hatch and crawl to the front..........any more ideas????
