1st Gen Keypad not holding charge

Hi, my keypad is no longer able to hold its charge. I’m creating this post after three full charges depleting within a day. I’ve contacted Costco and they’re able to accept my return but it’ll have to be the full set with all the motion devices. Is there a fix or a warranty replacement through Ring for the keypad? Hate to keep having to arm through the phone, please advise. Thank you
