Do not push too hard, take it to any place where they fix remote controls or tvs. The 
replacement is generic and cheap. I have a Roland JV-90 and it happnes all the time (and 
that unit has millions of bottons). 

They get damaged over time of moisture or even a bit of humidity. To replace the ones of 
the Emax is very easy but have a technician doing it so you get it right at first.

By the way, do not take it to a music dealer, they will charge you 10 times more.

I got a music dealer selling me each connector for $10+ labor, and doing the research I got 
30 connectors for $9 from a regular repair shop.

Like someone else said, you can take this to a place that repairs remotes controls.  Or if you are competent at taking the keyboard apart, then you can use this product:

The buttons on the keyboard version of the emax are part of one big rubber membrane and each spot there is a contact surface so that when pressed down, the contact surface closes a circuit and registers a button press.  Eventually the conductive surface wears off and so the circuit no longer closes when you press the button.

The repair kit above is a mixture that you paint on the contact surface to make them conducting again.  I used it for fixing this same type of problem on a Roland MC-4.  It doesn't take long and really the only thing that you can mess up is taking the keyboard apart and putting it back together.  

One of my friends actually fixed his emax keyboard buttons by doing this in a similar fashion.  Not hard at all.  Also, if you do go this path, then do all buttons at once because the mixture doesn't last and it would save you from having to do it again.
