Jose,
I have the 2010 model too. Seeing your post got me going again about wanting to figure out my keyless code. I found a post on an explorer website yesterday with a long list of numbers designed to try every code possible. It took me 30 minutes to discover mine.
Do a google search on explorer keyless code, print out the numbers, grab a beer and park in the shade. You'll have your code before you know it.:banana:
