I am flat towing my ‘13 451 and using disconnect. I was about to try the locking technique as others have described, but can not locate my second key! I had always kept it in motorhome glove box just in case the Smart got accidentally locked. Soooo, anyone have any advice on getting a second key? In a rather remote area, but will be visiting Medford OR and they have MB dealer, so if that is only solution, please let me know.
Love the forum and it has been very helpful.
