About a week ago when I tried unlocking my car from the driver side I noticed that when I turned my key there wasn't as much resistance as when I usually go to unlock my car and my key also got stuck in the door and my car was yet to be unlocked. To put it off whenever I get into my car I go to the passenger side to unlock the car and walk around back to the driver side to get in. I'm not that knowledgable when it comes to my car but I'm guessing that its either a fault with my door lock cylinder or the door lock mechanism(leaning more towards the cylinder). Does anyone know what might be wrong and how I can repair without taking it to the dealer??
