Hello, Richard -

The image here:
https://www.terapeak.com/worth/replacement-keys-manual-for-bunker-hill-electronic-digital-safe-model-45891/162049295398/
shows the keys for the Bunker Hill safe model 45981. The keys are in the center, lower part of the image.

The image of the front of a different model Bunker Hill safe from the owner's manual here:
https://www.manualagent.com/harbor-freight/0-19-cubic-ft-electronic-digital-safe/product-manual-2
shows here the key "slot" is located.

Best wishes.

Try banging on the top of safe with hand, rubber hammer, regular hammer with board on safe to spread the energy, etc. while turning the knob at the same time. Sounds silly but worked for me. Sellingdj......

To change the code: Your safe comes
preset with the default code of “159-A”.
To change the code, first open the safe.
On the inside of the door near the hinge,
there is a small red “reset” button. Press
this button until the Yellow LED on the
front panel lights up. Now, input your new
code up to 8 characters, followed by
either “A” or “B”. The Yellow LED will flash
to indicate that your new code has been
accepted. Warning: If the Yellow LED
does not flash, the code has not been
accepted, and you must start over.
NOTE: Be sure to test your new
combination before closing the door.
NOTE: Be sure to have the Override Key
available when setting a new
combination or changing batteries, in
case the door doesn’t open.

Good Luck

CHANGING CODE ON MODEL # 45891:
On the inside of the door toward the hinge, you will see a small red button. Press this button until the yellow light on the front control panel lights up. Now you can imput the new code (1 to 8 digits) into the front control panel, followed by either the "A" or "B" key. The safe will beep twice (2 times) to confirm the code has been changed. Important: If the safe beeps 3 times, then the code has not been accepted and you must repeat the above steps.
DO NOT LET THE BATTERIES RUN OUT BECAUSE YOU WILL NOT BE ABLE TO OPEN THE SAFE OR CHANGE BATTERIES.
