So once again, my door latch was frozen this morning ( i know, nothing new for us E53 owners ) I get in thru the passenger side which was also frozen, I start the car and proceed I hit the lock button on the center console to close the passenger side since that latch is frozen and wont keep my door shut. I get out of the car start scrapping the sleet off my windsheild and of course i lock myself out with the car running. I grab my other key, I manually unlock the door but nothing...I can't pull it open. I suspected that the latch was frozen so I grab a hair dryer (with an extension cord) and start heating the outside of my door right around where the latch would be, praying that this would work...after about 8 minutes the door finally opens..Of course then, I was 30 minutes late to work..( It took me several minutes to try to figure out what to do, after my other key wouldn't open the door ) Man what crappy morning!!
