Locked out / in our Georgetown 378XL

[Pitroes]

My wife and I are in a predicament. Our door to our 2012 Georgetown 378XL is stuck shut because the door mechanism internally broke. We are currently camping with the rig in FL, and really frustrated. I could not get back in the rig after we stepped out to visit a neighboring site, so the door was not locked. When we came back from the visit, the door would not open. The handle felt really loose, where it is usually stiff. After fiddling with it for a couple minutes, we borrowed a neighbors step ladder and climbed in through the drivers side window (luckily I didn't lock it this morning). I was able to remove the front of the door handle housing from inside the coach (removed 3 screws). I found that a piece of flat metal that basically extends from the handle through the door jam was broke in half. Problem is that it is still in the door jamb, and will not come loose leaving us closed inside of the rig unable to get out unless through a window. I pulled, pried and tried everything to get that piece out of the jamb, but I can't, and it is keeping me from being able to open the door. I saw a post on here from 2014, where someone had the very same thing happen to them. They needed a locksmith who drilled from the outside while he drilled from the inside to get it to where he could open the door. Anyone know where I would do this drilling to where I will not destroy any more than I have to??? I understand I am looking at replacing the whole door handle mechanism, but don't want to do any more damage than that. I also saw in that post from 2014 that there was a recall on the door mechanism, and I am betting the first owner of this rig did not take care of the recall... Thanks in advance.
