Answer:
In most cases I have seen, the ATM card is more limiting than a debit card, but the authorized signer has access to the account through many avenues including an access device such as, checks and over the counter transfers. You aren't increasing access to the funds that the authorized signer already has access to, so using a prudent card replacement procedure is all that is warranted.
