Both keys for my '16 F150 with remote start we falling apart, but I didn't need totally new keys, just needed the shells. Saved me a ton finding these!
2 reasons for 4-Star rating: 1) Longest and toughest part of the swap was popping the roll pin out on the flip key portion to put in my already cut key from the old ones. I could not swap it directly over from the old keys as both of mine had cracked and were near completely broken. 2) My factory keys had a little spot for an indicator light that blinks Green or Red if remote start was successful or failed. These new shells do not have that spot and so I'm left guessing if my remote start works if I am not within earshot of my truck.
Other than those 2 small issues, very happy I found these!
