It started yesterday, when it was 3 degrees out. I went out to warm up the car. I was able to unlock the car, get in, start it up, then lock it from the inside and shut the door behind me. 15 mins later i come out to get into the car and the door doesn't unlock and it won't budge even if I tried to use the actual key to turn the lock; it doesn't move! so I go around to the passenger side and I am able to get in. So, for the past two days, I've been climbing into my car through the passenger side, wth?! I hate to bring it into the dealer so they can try to scam me for hours of labor.
