Hello and welcome to just answer I am sorry to hear you are having trouble with your lock box. I know how frustrating that could be. I am not sure if you registered your box online or not if you did then you or your husband may have saved the code with your account. If not The only other way to get into that box will be to break it open. Here is a video that can show you how to do that.
This link will be the one to use if its possibly registered online. I hope you find this information helpful and if you do please rate with 5 stars at the top so I can be compensated for my time. Thank you and I hope your labor day gets better :(
