What kind of batteries does this door lock use?

Could use 4 AA batteries to power the door lock

will this work on a door that is 2.25 inches? (ie. larger than 2 inches?))

The instructions say "if your door thickness is 1.77 in to 2.17 in..." I don't know about your extra .08 of an inch. The lock comes with two sets of screws, on of them accommodating the thickness listed above.
