Hi @Clement1909, let me see if I can help out here! 

Your post has been translated to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.

Could you possibly elaborate your question a bit? Is the phone not asking for a pin code when it is supposed to or does the request for a pin code come up when it is not supposed to? If you want to add or remove a screen lock, this is done by going to Settings > Lockscreen and security > screen lock. 

Please do elaborate and I will do my best to assist you and let me know if I have misinterpreted your question in any way!
