I have a Sentry Safe H4300. I put a few important papers in it, but am unable to open it again to put more papers in it. Please Help! Thank you. Ruth Jackson
I have a H4300 Safe. To open the safe...
1) Unlock it with the tubular key
2) With one hand, push down on the lid (moderate pressure should do & preferably close to the latch area).
3) While still pushing down with one hand, use the other hand to squeeze the red latch button and lift up.
You can't open the lid by just squeezing the red latch button and trying to lift up. It won't. You need to push down, then unlatch, then lift.
Works everytime for me,...hope this helps. Read More At : Fireproof Safe...
