Went thru the process with select master key. Still failed the programming. May be the aftermarket key fob is bad. I also erase all the previous key.

i bought some key fobs on amazon and honestly never wanted to choke my self out trying to figure it out. i was lucky enough that my remote still worked but just needed some buttons good luck!! I’ve seen remoteremotes.com have their self program one but yet i had a hard time even doing it myself.
