Unable to open trunk

Hello, You should have a keyed lock on the trunk, and that will allow you to open it with the hard key. If the key fob is working, check the fuse for the trunk release as well. If you have folding seats, you should be able to climb into the trunk to release the trunk lid as well. There is a known issue with wires becoming frayed and broken on the driver side of the trunk lid behind the trunk liner. the harness rubs against the hinge and causes damage over time. There are other possibilities, but this is what I would check after verifying my fuse is good.
