Review on KeylessOption Replacement Keyless Entry Remote Fob Car Key for Ford Expedition Explorer F-150 Ranger Navigator CWTWB1U345 CWTWB1U331 CWTWB1U212 CWTWB1U322 by Shawn Welker

At this price, two keys and two remotes are a steal. As others have said, buttons are a difficult task to program. Unlike others, I had a hard time with the remotes. The vehicle did not go into door lock mode. After numerous iterations and variations, I finally disconnected the GPS and charger from the data ports. Bingo! The next attempt was successful. I had problems with programming "hanging" when programming two remotes in a row. I had to physically separate the remotes. Program one, move it away, and then program another.
