2021 Key Fobs - Can you mix styles of fob?

[aalbert]

I have a 2021 XLT 202A that came with a non-remote start key fob (it was a rental and then a lease, so probably stripped at some point). Vehicle itself can be started remotely using the Ford app, etc. (to me indicating that the capability is in there somewhere). I called a dealer today and they looked up the key by VIN, and said that I can use the remote start version of the key fob (cool). Question is, will there be any issues with having a non-remote start key fob and this new one on the same system?

my 2019 Expy Limited Stealth doesnt have remote start on the keyfob either, strictly via the phone ap.
