This was our second Cary safe of our trip. It was a real pain but there was nothing at all wrong with the lock so I couldn't give up. I worked on it for 6 hours the first day then packed it in. The next day with fresh eyes and a bungee cord (IYKYK) we had it done in 1:53:00.
I think I may set a protocol to walk away for an hour if nothing is showing up.
