Question: How do you set the combination.  I have misplaced the manual
Document: Great small safe that met my needs. It has a solid double bar locking system that would make prying the door open difficult. I had to use the included emergency key to initially open the safe door as following the directions included with the safe did not work. Once the door was open, setting the digital combination was very easy. The four required AA batteries were included along with two bolts to secure the safe to a wall or cabinet.
Not as I expected. Looks bigger in the picture and it's hard to put fingers in the knob. Thinking about returning it
directions unclear. safe will not open without keys. there should be a number for customer service support. i am going to return the product.
Answer: no
