To avoid this problem in the future, change your batteries every six months or so, even if you don't use the safe that often.

Hi again, I also wanted to mention that the yellow low battery light does not always come on to warn you that the batteries are losing power, if they still have a small amount of 'juice' left in them. If you have any additional questions or concerns, please don't hesitate to click 'Reply to Expert' before rating, direct your reply to me, " Cheryl", and I will be happy to continue to assist you once you let me know what additional information you require. I wish you much good luck with your safe! If you still can't open your safe, please let me know, so we can continue to troubleshoot.

If your safe also came with a key, make sure to use the key first, to pop out the cylinder, the remove the key before entering your combination. Slide battery cover back in place If you are sure of your combination, replacing the batteries should enable you to open your safe.

Once you move the dial, using the key alone is not sufficient to unlock it. Opening a Sentry safe with key and no combination might be impossible on electronic and combination safes. Note that the steps to open a Sentry safe lock box with key might be different for safes with a left-right-left combination style. The handle will be pulled down easily and smoothly if you entered the correct combination. In a clockwise manner, dial the third number of the combination and stop immediately as you reach it.
