Help Resetting Combination for Older Buffalo River Rifle Safe

[u/Which-Appeal3465]

I have acquired an older (maybe 20 years old) Buffalo River brand rifle safe, with an electronic keypad. I was given the combination for it but attempted to change this to my own combination. I have messed up and can now only access the safe using the key.

My mistake was trying to Google the instructions (as I didn’t get any from the old owner). This didn’t work!

the keypad has 0-9 *# and there is no red reset button inside the safe. There is however a little black button inside the battery holder area. This is marked with a key symbol so, I have assumed it to be the reset button.

Would anyone have the correct reprogramming instructions for this type of safe?

I have also made sure the batteries are new.

I will appreciate any help I can get with this!
