I have a little bedside safe, about large enough to fit a few magazines and a full size pistol. It has both fingerprint reader or can be configured to a push code. That part is battery operated. The safe also has a gem lock. I have it tucked down beside my bed where I just reach my arm over the side of the bed.
The company that built this safe were bought up by some other company and can't remember the name. I do remember a number of similar products from various other sources.
