Key Fob & FordPass wonky?

[Tbogo]

On my 2021 I noticed when using my key-fob to remote start the truck will start and then the key-fob flashes red 3 times. When pressing twice again to stop it flashes again 3 times and stops the truck. Sometimes it will flash green when starting. After a few attempts now truck will not start. Does the key-fob battery need replacing or truck battery?
Using Fordpass app I tried to start, lock/unlock doors and I get "failed notifications for those requests. Any thoughts?

Have your truck battery checked. I have a 2021 and the battery died a few weeks ago. All fob functions were being goofy before battery finally died. 3 years is about all you get out of these batteries.
