I have been able to do exactly what you need. Even if you stop the application through the running tab in the application manager tool, the service restarts itself. The only way to kill it is throught the force stop button next to the unistall option in application manager. Basically you call the Service directly. Here is My Code:

public class TestService extends Service {

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
        Toast.makeText(this, "Ejecutando Servicio ...", Toast.LENGTH_SHORT).show();
    return Service.START_NOT_STICKY;    
    }

@Override
    public void onCreate() {
      super.onCreate();
      Toast.makeText(this, "Iniciando Servicio ...", Toast.LENGTH_SHORT).show();
}

    @Override
    public void onDestroy() {
      super.onDestroy();
      Toast.makeText(this, "Deteniendo Servicio ...", Toast.LENGTH_SHORT).show();
}   

On client activity write the following code:

            Calendar cal = Calendar.getInstance();
        Intent intent = new Intent(this,TestService.class);
        PendingIntent pIntent = PendingIntent.getService(this.getApplicationContext(), 0, intent, 0);
        alarm=  (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(), 3*1000, pIntent);

And declare the service in manifest:
