Why people keep using mechanical locks when electronics is cheaper and could use unbeatable encryption?
- MattPalmer1086 4y agoWhat is the failure model when the power goes? Do you fail safe (unlocked) or fail secure (locked)?
- vbezhenar 4y agoFor safes you of course keep it locked. But provide some hidden wires to power the lock if battery died. Of course you should think about protecting electronics from something like megavolt put on those wires, but it's doable and with enough iterations all weak spots should be fixed.

- gsliepen 4y agoThe problem is that there are still mechanical bits inside electronic locks, and now you have two areas of attack: the mechanics and the electronics. And as already mentioned, they often have a mechanical lock mechanism as a backup for if the battery is dead, further increasing the attack surface. If the LPL is to be believed, a lot of electronic locks that are on the market are easier to open than Master Locks.
