i have a problem with my door locks, they are acting really wierd. everytime i want to lock it, i have to turn to UNLOCK them first then turn to lock them. is that messed up or what? and then sometimes its really hard to lock them, like yesterday it took me about 10 minutes just wiggling and trying to turn the key until they finally locked (then i realized i needed something in my car ) also the trunk sometimes acts up when i try to open it with a the key. but anyways, has anyone ever had this problem or does anyone know what it is and how i can fix it?

thanks
Carlos
