That Sucks,Sorry

What year was your garage door opener installed?

[Horatio Gates]

Is it possible another door was previously left unlocked, then later locked by the burglar and the garage was the burglars exit?

Some older garage door openers can be activated by any number of remotes

I had a burglar alarm installed in my Dad's house. The first thing the installer told me as we scouted sites for monitors was to fix the rope that hangs down for disengaging the door opener.

Burglers stick a hanger wire inbetween the top of the door and frame, hook the rope, and disenage the door opener's drive.

Voila! They are in.

I now tie the rope up so it can't be hooked unless I want it hooked.

I am sorry for your situation.

I remember in the late 80's, kids with the remote controlled toy cars were always opening up garage doors.

Having worked with many garage door openers, there is a very good chance that your openers code was stolen. If your opener is older than 2 years. The newest generation of opener is the only one that the criminals have not broken yet, to the best of my knowledge and they came out about 2 years ago. The criminals are getting a lot better at it also. With the increase in the ability of code cracking software to run at much faster speeds even the million roaming code openers are prone to being hacked. The best advise I can give is to get a new liftmaster opener that is a 3000 model number (3220, 3255, 3280, etc. ) Other than that, the crooks just drive around neighborhoods and let the code cracker work, if a door opens that becomes the target. The newer ones have vacation lockouts and override switches but those don't help on a daily basis. Sorry to hear about your loss.

Another thing that can break the beam, is something sitting near the beam path that gets blown or shifted into the beams path. It could be leaves blow in to the garage or a spiderweb near it that blew into the path of the beam and so on.

If the system is only 5 years old, then it most likely has the safety beam feature.

Do you have a dog door? I've been able to get through a dog door to get into my house. I even raised the door thing from the outside. It's pretty disturbing and we'll probably fix it soon.
