2001 Volkswagen Jetta key

If the power door locks don't work with the button inside the car, then you have a blown fuse and you need to replace that first.

Does the key fob have a small red led light that comes on when you press the buttons?

If yes, but it does not light-up, replace the battery. If it still does not lock / unlock, you might have to "re-matched" the remote to the central locking system using a factory scan tool (or equivalent aftermarket).

The trunk should still open by manually inserting the key and turning the key. If not, then the linkage in the trunk lid needs to be adjusted.
