That's a little weird, but lemmy.world is always having problems. :(
In my testing, a bad key would result in a 400 status.
The keys are stored in the database. Every instance will have new ones.
You may be stuck for a bit in the delivery retry queue. After a failed response like 403, we'll save that and try it again for a while. But new messages will line up behind the failed message. So effectively, you can't talk to lemmy.world until the 403 message times out. This is by design, but if there's a federation problem, it's not great.
You can peek in the database at the deliveries table, and delete anything with a rcpt of lemmy.world. Then try subscribing again.
