Burglar Proof Your Home #5: Patio Doors

This back patio door poses a unique curve. Number one is that it's got glass in it. So there's a vulnerable space for us. The other thing you'll notice are the hinges for the door are outside.
There are two ways for me to enter the house, I can either break the glass and go in, or with a hammer and a small screw driver I can actually knock the hinge pins out and have this door fall out.
We talked earlier about the hinges that had the pin and the receptacle on the other side. These hinges would be a great candidate for upgrading to the pin hinges. 

Interestingly enough, there is a deadbolt here which is great. This is what we call a single cylinder deadbolt. On the inside, what you're going to find is what we normally find, and that's a way to activate it with just a throw. It opens with by simply twisting with our fingers.

However, we would want to take a different approach with this door. We’d recommend using a double cylinder deadbolt instead. What that means is that the deadbolt on the outside would be mimicked on the inside. It would be a keyed dead bolt that would actually physically require a key to lock and unlock it. So if this glass was broken out, the intruder would still need a key to get this door out of the frame or to get it opened.

Safety laws in the United States mandate that these locks be designed so that if you lock it from the inside, it will not let you remove the key. Therefore, if you get into a situation where the house is on fire while you're in the home, you've got a way to get out of the door.


So we’d definitely recommend putting a double cylinder deadbolt on this door just to make it a more difficult target.
