What really happens when programming a garage door opener? Is the remote that gets programmed or the garage door opener? I would like to program a remote so it can open the garage door. Becaue I live in a condo, I do not want to program the garage door opener in fear that if the door opener is programmer, other people may not be able to operate the door.
I'm talking about the new style of opener which automatically changes the code each time it opens the door, not the old kind which has a fixed code.
