Yeah, it's a somewhat generic term for a key used by locksmiths, especially considering the mechanisms are a bit too complex for there to be a thriving competition for locks. There was probably only one guild in lower Lordran who produced doors and locks, and so having a general keyring that fit most would be handy for repairs.
