Yes it goes away in a few days -- If you had your windshield done be mindful of any stickers (registration, toll tags, dash cams, ect.) that you install -- you may want to use Sticker Shield (or similar) to protect the film...
I installed this one on mine last weekend. It seems to have decent reception.

With mine I had to program the door remote (transmitter) THEN program to the garage door. Have had to do it for my previous Mustang also.
Ford Support actually has a decent video of the process...
