Have you read for any codes?

Do the windows drop when unlocking?

The inside handle is manual operation

It could be the door lock which has a power supply to it

When I press the button on the key, it opens the drivers door but not the passengers door and I haven’t tried yet the key to see if it opens both I might have to take the door card off to investigate further

OK, so as you've edited it to the Passenger side not working that changes things.

Firstly Fuse 73 powers the passenger side lock.
But this could be a number of things.
So the system is working because your drivers side unlocks with the fob, this then points to the fact that the passenger side is either not getting a signal to unlock/lock of it is and there is no power to do such.
So I'd first check the fuse (73 as posted above). Then if that is OK you're going to have to take the door card off and check the wiring connectors for damage and corrosion.
