Removing the thing on the end of the electric trunk lock prevents the trunklid from jamming - so do it.

Now, if the top won't move as you describe, the most likely cause is the top open switch above the passenger's head or the divider switch in the trunk.
My experience has been that IF it is the top open switch, it will be obvious, as they tend to fall apart - turn the latch, push the top up away from the frame, get out and go around to the side and look in the hinge above the passenger's head - you will see the little switch.
