Issue with locking the doors

[Sawan]

Hi there, my Skoda Fabia doors doesn't lock. Only the driver side door locks with key and rest remains unlocked. I am able to do this manually only. Another wierd thing that I have observed is , all the locks rarely with remote and manually  and stops working after some time. Any suggestions

This would be better posted in the section for your Fabia, such as the MKII section. Hopefully this can be moved by a moderator.
