I recently purchased a 2011 f150, which only came with one key. I had a locksmith cut and program another key to start the truck (plain key, no remote on the head). I then ordered another key with the remote on it, had it cut, and have gone through all the programming instructions I can find online. I've tried the "turn it on for 3 seconds, then off. On with the other key for 3 seconds, then off. Then on with the new key for 6 seconds." Didn't work. Tried with the door open and door closed. Then went through the turning on and off 8x trick, no luck. Will I have to take it to a dealer or locksmith? Is it because I may not have the master key? Any help, links or suggestions appreciated!
