Even if cost is no object, every commercial electronic entry system I've ever seen has had at least one door with a bypass with a conventional key, in case the electronic entry system fails. And any electronic lock with a manual lock in parallel with it can never be more secure against attacks like lockpicking than the manual lock alone.

Of course, there are security benefits if you have a cleaner/dog walker/whatever and want to give them access you can revoke without the cost of changing your lock. Or if you're running a commercial installation like an office or AirBnB.

Still, I don't think electronic door locks will become mass-market until someone makes one so reliable it doesn't need a mechanical bypass key, which might be impossible.

You can pin a lock that's practically impossible to pick by permanently blocking when one attempts to pick them. Yes, the owner needs to drill the lock after such a picking attempt, but it prevents non-destructive entry.
