The mystery of the open garage door

Why did I find my garage door open this morning? I haven't opened it with the garage door opener entry pad for several days, and I know it was closed completely the last time I used it.

I have a detached garage off my back yard. (Lined up: house, back yard, garage). There is a standard door leading from the yard into the garage, but the main garage door can't be seen from the house because it is on the other side. So I can't easily see if the garage door is open or closed unless I walk around there and look.
I had a Chamberlain Whisper Drive installed last year that uses a rolling code transmitter. I generally open the door by either pressing the large button on the wall after entering the garage by the door leading into my backyard, or by entering my code into the keypad by the garage door itself.
But this morning I found the door wide open (Luckily, my bike and a few other valuable items were still there.) I don't have a car, so I don't go out to the garage daily, so the door may have been open for minutes or even days, as the last time I opened the garage door was Monday night.
So far, my theories are:
1) The small remotes stored in my back room may have been nudged so that the open buttons were pressed.
2) Someone guessed the correct code, opened my garage -- and took nothing.
3) One of my neighbours' remotes somehow opened my door, but given the rolling code, isn't this astronomically unlikely?
Any other theories? And what steps should I take to prevent this from happening again?
It would be fast and easy to change the code on the keypad, if this was somehow compromised, but I may have to actually clear all codes to make sure the small remotes are cleared, too, and only reprogram the keyless pad. (Remember, I don't drive and don't need the remotes, although I want to keep them if I sell the house so the new owner can use them).
