Today I tried turning the key to the 90 degree position and it didn't go. It felt like it's the wrong key. Have no idea what's going on. When I got the car, they only gave me one key but it does everything, except for the double locking thing. My driver side door lock is really hard to turn when compared to the passanger side and sometimes I have to turn it clockwise a little in order for it to go counter clockwise when I first open the door. Anyone has any clues?
