T20 is what you want, the instructions said a different screw driver unless they changed after 2011. You buy in a 8 piece set not by handle. Find your 3 letter color code(GAZ Summit white GAR Black Granite Metallic for example) and order them that way. I'll say do this with windows down in the event you screw up. The screw needs to be turned until handles come off and stop. You never at any point remove a single screw in install. 1st door will take you 19 mins then 4 mins for the rest of the doors after you figure out you were scared the 1st time.
