Very common problem with lot's of info here and elsewhere about it. I would take a heat gun and do mine. I am traveling and took my Lexus just for this reason. Didn't wanted to be stranded with the door locked or not latching once you get in. Have had both problems in the past. I have also used a propane torch, carefully of course.
