The other morning my car was frosted over and I went to unlock the door with the key (my electronics on the key stopped working awhile ago). It had trouble going in but eventually was able to turn it and unlock the car. After driving it I was able to lock the car but went to unlock it again and now it won't work. The key goes in and turns but it won't unlock or lock the car. The electronics are fine though (after calling AAA and being able to get in the car the doors still lock and unlock by pushing the button in the car so it only is something with the lock on the door handle itself). Not too much of a car person and was just wondering if anyone had any ideas of what the problem could be and if it's easily fixed. I was thinking it must have something to do with the fact it was frosted over but have never encountered a lock not working. Any help is much appreciated!
