Advanced keyless entry replacement fob

Does anyone know how to positively identify a replacement fob that will work with my 2015 Mz3 hatchback? Which of the numbers on the key are critical? I've found several fobs with the same FCC and model numbers, but there are 4 rows of numbers above the FCC number I can never match. (The attachment is a picture of the fob showing the numbers.)

Also, does anyone know if a used key is programmable?

thanks,

hans

I bought a used key on Ebay that had all the correct numbers. If the dealer won't program it you owe me $20.

The ultimate goal is to bust it apart and reassemble it into something thin enough to fit in my wallet. No more keys for me!
