Hi, my Mercedes central lock is not working properly. When you press the lock it won't lock all doors and it keeps going like a machine gun.

All four doors don't lock weather you are in the car or outside using the remote, and when you move it try's to lock and unlock. Please how do I fix this.

It sounds like the switch is bad and needs to be replaced or the control module. Pull the trouble codes and see if anything comes up. Auto Zone or Advance Auto will do this for free.
