Garage Door opens by itself. I tried to erase the memory and use the old remote that came with it but the yellow learn button won’t erase all the memory. The door open and close with out the remote Sears Craftsman model 41A3493-1 ID HBW41A3063
I had this happen with a none sears brand. when I added another remote to the opener my neighbors remote started opening my door. I had to change the dip switches on the remote and the door opener to keep that from happening. I would take a look in the manual or on line for that door opener system and see how to change the base code for it.
