Can't get it open
My son got this for Christmas. We put batteries in and tried the default 0-0-0 combination which is supposed to open the door so you can program your own combination. Everytime we turned the knob trying to get to zero, we only got about half way when it sounded this buzzing alarm like someone was breaking into it. I wrote an email to the company to see if they have a solution. I will update if we finally get it to work.
