How to uninstall defective peephole cam to install replacement.

I have a defective peephole Cam and requested a new replacement which just came a short while ago. I just realized that there will be new codes involved to install my replacement peephole but don't know what I should do to delete the codes from my defective cam which I will be returning. Should I delete the entire Ring app and try to start over or will I just be making a bigger mess of things by doing that. Help please, I really don't know what to do about this. I may be making something more out of it than it is but I don't know what I don't know, if that makes sense.
