Our Craftman garage open (Part#41A5021-3C Date 10/98) broke down and we replaced it with a unit (Part# 41A4315-7D Date 07/97) that we had on our other garage. The keypad keyless entry will not work and doesn’t seem to be sending a signal to the older unit we installed. Is the 97 unit a Security+ compatible garage door opener receiver? Note: the battery is new.
