I checked the fuse and changed it out with a new one. I do hear a clicking noise, but still not opening. I tried resetting the automatic door locks and that didn't help. Again, my key does not work in the trunk either, which leads me to believe tha the lockout feature in the trunk is switched to on...although I should be able to use my key to enter the trunk.
Any further thoughts?
The key should still work, but there may be a problem with the release cable between the key cylinder and the latch. The electric release is likely not working because of the latch switch in the trunk like you suspect. Removal of the back seat is how you are going to have to access the trunk.
Lift up on forward edge of the lower seat cushion, then remove the lower seat cushion. The seat back can then be removed. Remove the bolts at the bottom and then lift up on the seat back to disengage it and remove it from the vehicle.
