Q: iPod 5

If you are the original owner/have original receipt than I think the cost is free.

Otherwise Apple will not remove the activation lock.

Are you the original purchaser and did you purchase if directly from Apple?

If not you are out of luck

From whom did you purchase it from?

Then go and talk to who ever you bought it from. They will need to give you a receipt for it.

Why can't you recovery the password?

How do I change or recover a forgotten Apple ID Password?

I have multiple Apple IDs. Is there a way for me to merge them into a single Apple ID?

Then recovery/reset the password
