Finding the factory keyless entry code on a 2011 Flex.
This bodystyle runs from 2009-current, and the procedure is the same for at least 2010 on. As I said, I believe Ford starting doing the printed code on the front of the SJB in 2010, which makes it so much easier to get. Generally before 2010 they're printed on the sticker on the backside of the SJB, as seen in the Ford Escape video:

Ford started doing MS-CAN and the SJB (Smart Junction Box, which is an interior fuse box/'BCM') in ~2006, almost every newer Ford with keyless entry will have the code printed on the SJB.
Save yourself a trip to the dealer (usually a half hour labor) to get the code, it literally takes 3 seconds if you have a flashlight handy.
