2021 RAM 1500 Limited, remote functions failed fixed

[sethram21]

I lost all remote functions from lock/unlock and remote start yesterday. I went to Ram Dealer yesterday and this morning to talk with the service advisor. I ended up making an appointment for a check-up next week. After picking up my kids from school this afternoon, I removed the battery cables for a few minutes and put them back on. The remote functions work again. I am unsure if this will be a good fix, but it works now.

This is weird. I literally just made a post about the exact same thing happening to my 2021 1500 Limited. Happened to me last week, battery disconnect for 30 mins and then worked again and fine for over a week and then just happened again.
