Thanks for the advise folks, I just discovered how to lock the door opener so it won't work even with the remote. That solves my problems for when we're out of town or away from the house. I'm going to wait and see what happens, hopefully it was just a fluke and won't happen again but if it does I'll look into getting it re-programed as it turns out that's a little expensive. I'm also going to change the code just in case
Thanks again for the input!
