I don't normally lock my lids unless I've got something "special" in there, or am losing site of my bike for a time period. This past week I had to do so several times. I've not ridden the 17 CVO, but I have played with the locking lids and must say, push button remote locking steering and bags sure seams NICE. Lazy, but nice..... 
Wonder if a 3rd party kit will come out for the SG and SGS.
