The difficulty of this attack is definitely in producing so many test keys. I imagine that it might not be much easier than disassembling the lock.

- aidenn0 4y agoYou need one test key per pin, so on the order of 7 keys; that's not so terrible.
- vgel 4y agoDon't you need (up to) `N cut depths - 1` keys per pin? E.g. if there are 4 possible cut depths for a pin, and your key has depth 3 on pin 1, you need to (potentially) test depths 1, 2, and 4 -- and if none of them work, your key shares a depth with the master key.
- vgel 4y agoOh, you could re-use the same test key if you start at the higher depth, of course.
