I checked this several times. I tried it both ways
but am reasonably sure that when the button
is out that it is not engaged.
The information about the fuse box was great as
it obviously sent some power into the vehicle. It
just didn't allow the trunk to open yet. I do not
think it is a matter of letting it 'charge' for awhile,
but I did this for a few minutes anyway. I would think
it would take very little power to open the trunk if
everything else were okay. It used to open easily
before I let the battery run down (big mistake).
Would a pop-a-lock guy (yellow pages) likely be
able to open it without damage? I have no idea.
