Interchangeable key fobs?

[yeet1331]

I have the square-looking key fob for my ‘05 Limited but I really like the current 2018-2020 fob design. Is it possible to program a new fob like that to an older Explorer? Or any newer fob for that matter?

Interested in the answer as well

Don't know, but that's a long time between them to still be compatible, although anything's possible.

Switchblade key from Amazon or E-Bay? I've used one for several years with my Explorer.
