Liability - Deadbolt keyed on both sides in door with glass?

[Jonathan Taylor Smith]

I have a back door of a rental unit that has a large glass section (as seen below); and I wonder if I am potentially liable on either side if...

1) Someone just breaks the glass, reaches in, easily unlocks the deadbolt from the other side, opens the door, walks in - and cleans out the place...

2) Or to prevent this, I put a deadbolt on the door that is keyed on both sides, but then there's a fire and the door cannot be opened for escape without a key!

I do provide an alarm with monitoring included for my rentals, which I'd assume lessens my liability in the case of #1 - but just the opposite could also be true. Where does my liability lie?
