reset worked for me (2003 S)
After losing 2 hours of my life fiddling with the damn thing (including rigging a nylon rope up to the parking brake to try to get the damn thing to stay closed) i finally gave up and checked this forum.
My battery had sufficiently drained, requiring me to get a jump start.
The combination of cold, snowy weather here no doubt aided the problem.
Just squeezing the boot release reset it and let me close it!!!
I'll still have it checked by a "professional".
Thanks guys: you always rock!
