David Jones' EEVBlog had an episode attempting to do powerline analysis of an electronic safe: https://www.youtube.com/watch?v=HxQUKAjq-7w https://www.youtube.com/watch?v=HxQUKAjq-7w Like other commenters here I'm wary of using an electronic lock because I'm not able to inspect the code for backdoors. I wonder if there's enough of a hacker market to warrant creating a crowdsourced electronic safe (or retrofit of the electronics of an existing electronic safe).
