Ford Key Fob - 3 and 4 button

I own a 2005 Ford Freestar (3 button) and the key fob broke at the key ring area. I didn't have much luck with the snap together models already available here so, I made my own screw together design. I did find a similar design from 2012 but this one was made mostly from scratch/sketch. I can verify the guts from both the 3 and 4 button key fobs fit ok.

You'll need two m2 x 8mm screws to assemble.
