So what? Get in the garage, wait, then go into the house and set off my alarm. You really want my TV, laptop, phone or silver? Take it. Insured and replaceable. Unless they deactivate my alarm system first, by the time they find anything of value that alarm is going to be screaming and you'll most likely find yourself staring down the barrel of someone's duty weapon. If we don't answer, the police are summoned automatically. If no one's home, I don't care what you take. If I'm home-well, we won't go there!
BTW we have a window break and motion detector in the garage. Again, unless the whole system is completely deactivated prior to entry he isn't getting very far. Once the garage door is open the motion detector will trigger the alarm. You can't stop pros no matter what you do.
