ok,i bought a sammy and on my very first outing(same day) i got a flat tire tryin to go through a deep puddle.no big deal i have a spare mounted on the back! no key for wheel locks but have tool box,hmmmm,flat bastard file and cresent wrench,hmmmm yup it took a while but it worked! at home you take your trusty 4.5 in. angle grinder and grind flat spots one the locks then use the wrench to remove. ps don't tell anybody this cause i wouldn't want thisto get out!
