new FOB key (3 button) will it work

[cuteako105]

my OEM FOB key for my 2014 CX5 has only 2 buttons (lock and unlock), if I purchased a new fob key with 3 buttons (lock, unlock and trunk release) and duplicate the key, will the trunk release work on my 2014 CX5?

I assume you would need to first see if the trunk has a frequency and then if it can be programmed into the third button on the fob

how do i know if it has its own frequency?

Your owners manual perhaps (uhm)

If it's a Sport, I'm going to guess no.
