How far can you drive without the key fob

Never heard of that, the chip is in the key. FOB is for convenience.
FOBs are good for starting, but once it shuts off and you don't have the FOB, it won't start. On a Harley-Davidson motorcycle, if you don't have the FOB you can enter a code to bypass the FOB as long as you know the code. Not sure on your Mustang. Suggest reading the manual.
