New to me 2020 Sport wont start

[map246]

I have had my truck for about a month. Everything has been great. No issues whatsoever.

Drove it yesterday morning and parked it in my driveway. Went out a couple hours later to leave and no start. I pushed the button and just ONE single CLICK. Everything inside (electronics) is working properly. I plugged in my OBDII and it is not showing any codes.

83k on the truck, battery date of manufacture shows 07/2022.

Based on what I have been able to find online and in these forums, it is most likely the battery, starter, or starter relay. I started with the easiest and changed the relay....no change. I took the battery to get it checked. Showed to be a "good battery" at 12.2V. This is a little low, but still should be enough to fire it up. I am having my son-in-law change the starter this afternoon. I am trying to avoid the tow and trip to the shop.

Without going down the rabbit hole of all the obscure things it could be, am I missing any more common causes here? Both keys are working, so its not the RF hub.

Should I change out the battery while I am at it? I have a connection that can get a battery for about $125.

Sounds like the battery is the issue. Push to start vehicles won't even attempt to start is the battery is too low. Easiest way to know is to get a jump. If it starts, then you know it's the battery.

That would be my second step after making sure the terminals and ground connections were clean.
What is the voltage under load when attempting to start?
