Although dealers said No in the past, my local dealer says they can program a SmartEntry key fob from one 2015 Fit to work with another 2015. The same applies to keys for the 2019/2020. At "about $100," it's cheaper than buying a new key, but I think we'll get by with the two keys each of us has now. It would take about an hour, and I'm assuming that all keys would be programmed together to work with the car, rather than adapting the "foreign" key to work with the system.

 

if interested, I have an "easy honda key maker" laying around ..... PM me

 

Thanks, but if used that, I'm sure I'd wind up with no keys that worked.
