Anti Theft Light Blinking

Good Morning,
I just noticed that this morning that my anti theft light is blinking in my 2018 Tundra, I have never noticed it before. I have had the truck for over 3 years. Also, my key fob isn't working, and yes I have replaced the battery in the fob but, it still doesn't work. I use my aftermarket remote start system to unlock and lock the doors. And it has been this way for several months. Has anyone had this light blinking on their truck? And if so, does it wear down your battery? And any thoughts on why this would have started now? Thank you, all information is appreciated!!

 

is it blinking while the truck is running of just when its off?

 

Just when the truck is off, thank you!

 

Yeah, my 2018 does the same. Doesn't matter if the doors are locked or not. It won't drain the battery since it is a quick LED flash. I think it is just part of the lecture scene the 2018 has in other areas too (like the start-up screen that wags it's finger at you for being so stupid that you shouldn't even consider driving this thing).

my 2019 blinks when off and it sits up to two weeks sometimes. haven't had any issues.
