Cycle the key 11 times and see what happens.
You probably wore out your key switch with all of the cycling.
Seriously, replace the battery in the FOB, and try again. If it still doesn't work, your truck does not have remote entry.
Some of the trucks you have to close the door, press lock button on the door itself, turn the key on and off 8 times, then you will hear the locks cycle. I did not see the step about hitting the lock button on the door in the instructions posted. Might be worth a shot.
