To join a locked Roblox group, open the group’s page and tap Join Community or Join Group if it appears; if the group is locked/private, you may need approval from the owner or admins before you’re accepted. Roblox’s help page says some communities require manual approval, and community owners can also set specific requirements for joining.

What “locked” usually means

A locked group is often one that is private , member-only , or set to require approval. In that case, you usually cannot instantly join the way you would with an open public group.

Try this

  1. Search the group name on Roblox.
  2. Open the group/community page.
  3. Look for Join Community or Join Group.
  4. If it asks for approval, submit the request and wait.

If the group is tied to a game

Some Roblox games only allow group members into the experience. In those cases, the group itself must be joined first, and the game access setting may be “Group Members”.

If you can’t join

  • The group may be full, private, or closed to new members.
  • The owner may require a manual review or a message before approving you.
  • If the group was “locked” after you already joined it, you may need to find it from your account or profile and leave it from there.

If you want, I can also turn this into a short forum-style answer with a title and bullet points.
