Turns out powers tools work well on non-Turing complete locks too.
The interesting part of the threat model for smart locks are cases where a physical attacker is _not_ present.
- kelnos 7y agoThe article points out that the lock casing is made of aluminum rather than steel (presumably for aesthetic reasons), which is trivially easy to drill through. A steel casing would take a lot longer and make a lot more noise. The point is that people in the market for smart locks need to additionally vet the company that makes them for their proficiency in physical security, not just in software security. A competent company that has made non-smart locks for a while would not make this same mistake.

My lock has a freely rotating piece of metal that covers the keyhole - you cannot drill through it without first preventing it from rotating. More advanced locks jam when drilled through. There are also materials that emit lots of smoke when drilled through, mostly used in safes.
