Hi ..........there are a couple of things I would like to try and hopefully it will be a simple fix .........first turn your dial 3 times to the left to clear........then hold up the handle and put in the combination and try to open.......if not do the same thing and this time hold the key in to open position and try to open it .....another thing to do is tap all around on the door it with a rubber…… wooden mallet or a hammer with a rag wrapped around ..while lifting the handle might need to try this a few times .....if it opens, then empty the contents from your safe, lube the solenoid and any other moving parts including thee hinges with WD-40, flex the handle a few times shut it and see if that did anything.......please let me know

I went around with the hammer. I've tried every combination I can think possible..... all the ones you gave me x's 3.......nothing is working!!!
I really need to get the contents out! PLEASE advise.......

It looks like you will have to call in a locksmith if it is an emergency.......he can get it opened
