Thanks for the response, i re-surveyed today ; the gate you refer is here : https://www.openstreetmap.org/node/12009256097 , comming from https://www.openstreetmap.org/way/73491802 there is no signs or gate to restrict access ; i have  set https://www.openstreetmap.org/way/28179985 with access=customers and removed the restriction to the accessible roads.

Have a good day.
