2010 Fiesta Edge - Which Remote Fob?

[ToneEQ]

Bought my wife a second hand 2010 Edge and it only came with one manual key (likely not original) which has a red insert containing a 4D-63 chip.

I'd like to get a flip remote fob without paying dealer prices, but I don't know which type came with the car originally, or would either type work? (please see photo attached). Car has central locking.

...and has anyone changed their key blade in the remote on the right? Do the key blades look like the ones pictured next to it?

Either will work.
