Do I need PS plus to redeem golden key shift codes

ok not sure if anyone who doesn’t have PS plus has tried redeeming golden keys but my PS plus expires in july and I am considering not renewing it would I still be able to redeem shift codes without PS plus from my understanding PS plus is only for online play so I don’t think redeeming shift codes is considered online play but I believe on xbox 360 if you didn’t have gold you couldn’t redeem shift codes

You don’t need to have PS+ in order to redeem shift codes. I have redeemed them, but haven’t got around to purchasing PS+ yet.
