I'm no good at keyboards either and I dislike practicing, but when I have a song that needs some more instrumentation beyond my guitar, I figure out the chords and melody line on the keyboard and create a part to play. It is usually beyond my ability to do play this but when it is my own song that needs help, and I know no one else is going to do it, I make it happen. It might take me hours and hours of resetting that record button but in the end I can do it.
Necessity is the mother of learning keyboards..
