Micra K12 keyfob programming method that works?

Ok, so i got a second remote for my nissan micra -03 since the old remote is not working that well all the time..
So i tried all the tricks i could find online to program the remotes for the car.
But, none seem to work. I just cannot get it into programming mode. Its the normal keyfob (not keyless).
Opening the locks and cycling the key six times (or more) didnt trigger the programming mode..
So i am asking, is there another method that works on the K12? And yes, all of my door switches are working (confirmed by obd test).
