Standing on the right side of the bike...
Leaning with your right hand on the back of the side (pushing down)...
rotate the key counter clockwise, or turn the top of the key towards your bike.
Thanks for all the input - earlier post by "Bohica" - describes the problem - able to
push latch from rear of left side with thin, long screwdriver and "popped" latch mechanism - the cable had jumped out of the holder and after using a tie wrap - should function okay - Lineside
