Doors and console failure
 

I have a 3.3 v6 grand voyager on a 51 plate ,when I went out to unlock the car this morning the key fob wouldn't work and the alarm went on , so I unlocked doors manually and put ignition on which stopped the alarm sounding but then I noticed the electric doors where no longer working and also the radio and heaters won't power on now either ,can any body help me please!!!!!
