You should be able to open the door manually.
It could also be that the battery is completely dead, and that there is no signal in which case you could open the trunk manually too, to charge the battery, but I'd check the battery with a volt meter first to ensure that it either is the batter or not.
If this doesn't work then you'd need to call a locksmith to open your vehicle and determine if the battery is kaput or not.
Now, if all is well and your driver door still doesn't unlock it could mean that its the actuator or if its not that then your GM5 Module that controls the locking system which is also known as your ZKE module.

Goodluck!
