Hello Juanesa;
            I wonder if you cleaned the battery terminals off, are thet dirty ? and  are you shure that the battery is ok, did you check it with a meter ? at times the battery can seam to be ok as it will turn on the lights and radio
but will not start the car. and if it turns out to show that the battery is good than it could be the starter or selonoid.but I would first test the battery  ok
