Here's how people break into your house using a coat hanger and what to do about it. So here are the four things you can do about it. Number one: place a tie rip over the part that they push/pull down, number two: unplug the garage opener, number three: install a lock, that's what these are here for, and last but not least: please take out your garage opener. Too many people leave their cars open and this is all they need to get in.
