doh! They have tamper proof hinges that are secured by set screw that can't be removed unless the door is opened. Trust me, it's a lot easier to kick in a door it doesn't take much force.
To to OP, make sure you get that safety hinge if you do decided to have door open out.
I figured they had to have some sort of special set-up, I mean...this issue is not a new one.
I will look into the door monitor thing too.
Final word on the issue: GF got home, she said the garage light was on. Not uncommon for my mom to leave it on...
The key in the door was a mis-text, it was OUR key and it was just in the door, not broken. Nothing missing or moved she said, at all.
So I now am under the assumption my mother left the key in it(not uncommon, as sad as it is, it's really common..house door too) and the over head door just needs to be greased I'm sure or the sensor had something fall in front of it.
Needless to say, I will still be investing in security, with the bike in there soon and just less drama in my life would be nice, lol.
Thanks again for all the input and ideas guys, it's appreciated
