I have a 2008 convertaible with auto.

THe car had been setting 30 days so I went to the garage to put on the trickle charger.

I discovered the battery was dead and I could not open the doors or trunk.

I inserted the key that comes with the FOB to manually unlock the trunk so I could access the manual door openers. THe key turned 90 degrees and the trunk would not unlatch even with pressure applied to the lid when key turned.

What now...anybody?
