The keyboard can be as difficult or as easy as you want to make it.
I know people who are in a band playing keyboards and they can only play a few chords. It is also possible to use an automatic accompaniment by holding down one note with the left hand and playing a simple tune with the right hand.

This is the quickest way to play the keyboard but I think many people will want more of a challenge and a greater feeling of acheivement by learning to play properly with both hands.
Getting Started
Perhaps the most important tip anyone can give about keyboard playing is to
learn to read music. Of course this takes some time and is a gradual learning process over a long period.
Start with simple tunes that have step or scale-like motion – Spanish Eyes is a good example. Use sounds that sustain such as strings so that long notes won’t decay and left hand chords will remain sounding.
Most keyboards will also have acompaniment rhythms that play both drums and instrumental sounds by holding down one left hand note.
It is also great for composing your own music and you can produce backing
tracks for vocals on the computer.
Learning to accompany songs and vocals, rather than only playing melodies, will add a new dimension to your keyboard playing.
Being able to play lots of chords and understanding harmony will help greatly in becoming good at accompanying singers which, if you sing yourself, would be a great ability to have.
Another aspect of keyboard playing is that you can simulate the sound of other intruments. You can be a brass section or string section as well as a piano player.
All of these have their own playing style and that makes the keyboard a very demanding instrument when played at this higher level.
