Yeah, using the code < LOCKED> doesn’t actually lock anything, it’s just a colour. You need to lock it with code.
The easiest way is to do this:
Here’s what the template usually looks like:

You don’t have to delete anything if you just slip an override in there.

That will drag your reader out of it.
If you want to do it the “right” way, there’s a lot more to delete, and you have to do it just perfectly or the cc template will fall apart. You can ask Dara for help in her cc template workshop thread, or maybe she already has a no-skin template on that thread.
