patio door lock:
Item is design well and works smoothly. I had to drill and tap 2 holes into my door to secured it. I also had do some grinding so it will sit flush to the door. It is not the fault of the product. I just want to have it sit flush due to the way my patio door was build.

The only kind that can be installed outside or inside of the sliding doors:
There is probably hundreds of different types of patio door locks and I have searched extensively for a kind that can be installed on the outside of the patio doors. This is very useful in apartments that use the patio as the entrance into the living area. If this lock isn't compromised, you know no one has entered your house through the sliding doors.
