Comment Re:Why not have mechanical security too? (Score 1) 147 147

Are you unable to understand English? If it's a "secondary separate lock," how does that help if the primary, electronic lock fails to open? It's still locked.

And, if it's a secondary, mechanical unlock, then how does it prevent the hack at issue from being effective?

OK, I'll play.

it would be a good idea to have an old fashioned mechanical lock alongside the electronic stuff so if one system fails the other is still in operation? Also what happens in a power cut?

So, you seem to be describing this mechanical backup in two different ways - first, as a backup for the locking function. Second, as a backup for the _unlocking_ function. Which is it? Do you mean for the mechanical system to also need to be opened in order to open the safe, to protect against electronics hacks like this one and eliminating the advantages of an electronic lock? Or, do you mean it to allow the safe to be opened even if the electronics fail, reducing overall security?
