If BP were a game then @Ben Leybovich  just unlocked some wizard-level achievement for humble-bragging about his REI address book.

One person told me to just leave it unlocked at all times. 

I am trying to get a HELOC to unlock some of that equity for more repairs.

Also, if when you get there and the door gives you some trouble with your code to get in, just send me a text or call at .... and we'll unlock it from here.

depends on how worried you are that one of those doors will be left open/unlocked by a guest.

Any recommendations in the Austin area of who might be able to point me in a good direction re: the potential unlocked value of a property?!

For example, the seller and I were getting quotes for some contingencies and Nate didn't bother to show up and unlock the door at a time when he was supposed to meet with the contractor. 

Value - Quite often there's hidden value in a home that can be unlocked pretty easily.

Much better than leaving coins in an unlocked laundry room.

There are transients in the area that have been getting in the previous unlocked doors.
