Man mine is stuck too!!!
I installed a hot bodies undertail kit and it called for relocating the key cylinder which is connected to the lock release by a cable....well guess what at one point I noticed the cable came free of the lock release (when I had just taken the seat off...so i fixed it and put the seat back on.
But since then it seems it came loose (probably from riding vibrations), cause now I turn my key and it turns ok, but the lock release is not activated!!! I have no clue how to get under there and release it!!!
I can't get any tools at all under the seat and can't get the cable reconnected at aaaaaaaaaaaall!!! I'm hoping I don't have to mangle the seat and reorder a new one!!!
At some point I may have to get under the seat to do anything with the lights etc. Any tips?
I'm thinking of pulling as hard as I can on the rear of the seat and busting that plastic hook thing, then just bending the seat enough to get a tool in there to release the lock, then fixing the pastic hook at the rear again. My fear is that I may warp the seat!
