Hi Bill and all the rest of you...
I too am new to this forum. On my maiden trip with our 2011 Scamp
I managed to drop my key in a Walmart parking lot. Didn't notice until I arrived at destination. After extreme anxiety, and consideration given to trying to take the door OFF, I wandered over to another Scamp
owner in the campground and asked if they might be willing to try opening my door with their key. It WORKED!! We had a spare key inside the unit, and I was able to have duplicates made at the local hardware store. Since that time we've also learned that Scamp sells whole replacement door locks.
