2014 C-Max key and fob just had this done at professional locksmiths,exact match for original key and fob,the case is identical to original.
I paid £120 all in and really happy having two sets,gives me a piece of mind.
Key cut is perfect,both fobs lock,unlock,open and close Windows and pops the tailgate open as it should.
Keb fob flick type,three buttons,CR2023 battery.
Happy bunny now.
