Hi all, so the barn door(s) on my brother's 98 Yukon wont open. The doors are closed and are currently stuck in the "lock" position and will not unlock/open when using the interior switch or the key fob. The key itself does not work either...I am able to insert the key but I am not able to turn it to unlock. So as you can see this presents a problem as it is a daily driver. I will spray some graphite lubricant in there tomorrow to see if I can get the key to work but if that doesn't resolve it what are my options? Has anyone had this problem before with their barn doors (or any doors)? Any help is appreciated
