Pretty sure I tried this already but will try again tomorrow when I can get to the truck. Other background info. RFA low battery was showing for at least a month but I disregarded it because I figured I could always use the key. Suddenly the door locks went up and down while I was driving and then the truck shut down with the padlock icon lit up. I put a new battery in the key fob and then I killed the truck battery trying all sorts of stuff. I charged the battery and today tried the "key on wait 10 min/ turn key off 5 seconds/ repeat two more times." Thank you. I'll try the key in the morning. Good night.

No. Using the key did not work. Interesting note. The key fob buttons only work to lock and unlock the truck when the key is in the ignition and in the on position. The padlock icon is still there and the truck will not turn over or initiate any kind of starting.
