Hello and welcome to OSM!

access=no is not applicable most of the time as this makes routing impossible for literally everyone.

When there is a sign telling people not to access a road, this is usually done by using access=private (for all means of transportation), or using e.g. motor_vehicle=private when only driving by motor vehicle is not allowed. Further info on this can be found here https://wiki.openstreetmap.org/wiki/Key:access

Could you double check the ways you edited by using the above guidelines? If you need help, just let me know :-)

Apart from that feel free to join the forum on https://community.openstreetmap.org/

All the best!
