Am I?

The one attack vector you provided that actually applies here is something that would require technical experience above what your average thief would reasonably have. But with a keyed deadbolt, a lot of those can be raked, picked, or opened with a Lishi tool.

So yeah, you're right that there's a vulnerability when locks are paired. But that would require someone to either be within range when that happens or to place a battery powered device and pick up that information the next time pairing happens. Pairing doesn't happen very often. I think the last time I paired any of my locks was over a year ago.

But with keyed locks, an attacker wouldn't have to wait for me to do anything, they could just walk up and pick the lock with tools that are easier to get and understand/use.

Going with your reasoning, the two videos I've shared about picking deadbolts would mean that keyed locks aren't secure either.
