Just picked up a 2012 tl sh awd today, the key fob wont lock or unlocked doors or trunk, could tgis be a blown fuse? I tried reprogramming the setings and still nothing, anyones help would be appreciated, o and red light on the fob blinks whrn I hit it, so its not the battery, or the buttons in the glove compartment

 

did you try starting the car w/o the fob what does the dash information says and just because the led responds on the fob doesn't mean the battery is 100% replace the battery first if you haven't done so yet duracell 2032 should be your size. then reset the system remove your battery....

Yes, try replacing the battery first, and only use a good name brand (Duracell, Enegizer)
