Doors won't lock
Battery is fairly new, about 1 year old all the locks are not working electrical.

So the locks will not work manually, or using the key fob? Lady P has certainly given you something’s to check. Relays and ultimately the security ECU.
Let us know what works and what doesn’t. Right now your description makes it sound like nothing will work manually or remotely.

# 4 / 10 amp Trunk fuse box
pin position # 2 ignition switch provides a ground
pin position # 3 ignition switch provides a ground through the inertia ( crash ) switch
all door relays get there power from fuse # 1 / 15 amp RH heelboard fuse box
The trunk relay is # 8 / 15 amp Trunk fuse box
Since you have a issue with both trunk and doors this points in the SLCU direction
To trigger the SLCU there are 2 switches in the door lock that can be looked at with a meter
Beyond the electrical side there is the mechanical side where the linkage wares out not allowing the switches to do their thing
This area I have not tinkerd with but I've seen post covering the mechanical
