Hi first I think you should disconnect the battery and reset every thing and see if there is any change in the reception of the door code (don’t do it if you do not know haw to reset the windows sun roof and radio code etc) Some times it is a mater of the receptor deactivated or broken ,this is not very common but it does happen to change it is very easy, I would do first a reset of every thing and see if it works O.k.
Keep me informed.
Saludos cordiales,
Pascal.
