Key fob problem may be figured out
So I posted a while back about my tire pressure monitor and key fob not working. This weekend I was doing some digging and found a post from someone else with the same problem. They also posted a tsb number, 08-03-16-001B. I’m guessing I’d have to take it into a shop to have that looked at?
And would inoperable door locks be a separate issue?

IF the TPM reads ---- and the remote can't activate the learn mode you need to get someone with access to tis2web and a computer to upgrade the firmware in the RCDLR (a GM dealer).
The door locks are a different issue.
In your last thread you mentioned a light on the dash lit up when you tried to unlock; what light was that.
You might look at the RetainedAccesoryPower relay #32 and fuse #26 on the BCM. The door lock and unlock relays are integral to the BCM; the driver door has it's own relay; they are not serviceable.
Do your interior lights dim out? Does the remote start work?
