They'd been doing this for years with safes and combination locks, although this technique will require algorithms.
Efficiency likely depends on how much you train the software.
Just found it kinda interesting. It gave me a couple ideas on making a phones audio more secure -

The article mentions hijacking the targets smartphone mic. I don't see it being overly practical without doing that or being across the street with a parabolic mic.
You could also toss an fm transmitter + amplifier near the lock.
Edit, with a transmitter + amplifier, it may pick up the noise from roughly 40 feet away, maybe a bit more -

2020-08-25 at 12:15 AM UTCI'm surprised phone microphones are sensitive enough, though it's possible they're not and it's just the dailymail sensationalising things
-
2020-08-25 at 12:19 AM UTCYou'd have to have a very good directional condenser microphone pointed directly at the tumblers from a distance of just inches.

That's false actually. It's what I'd think too, but with control of the analog to digital converter and baseband chips operating system, ads are customized towards even the quietest conversations people have via that mic. I have discussed this with friends who have direct links to upper echelon in US national security, and I had to explain to them, even putting the phone under a pillow won't stop the recording
Not even taking the battery out will. I've posted about all this research here before. -

There have been many stories and videos on this. The GPS tracker even works with the battery removed. -
2020-08-25 at 4:17 AM UTCFYI, rf illumination at 2.4 GHz and 1900 packets per second can pick up audio from a very good distance via loudspeaker, with no battery in the phone necessary.
Google it if you need to. The mics also catch way more audio than you'd think but the baseband os and adc strips a lot away. Depending on frequency, as with radio, lower frequency travels further.
The speaker and end user software may hide a lot from lay people, but there's a wealth of info if you know how to access it -

That's partly because the software is designed to make the person think the motherboard has no power when the battery either appears dead or is removed.
Rf illumination actually is rather unique to the manufacturing process, so illuminating the loudspeaker, for example, with battery removed, will still have enough data to uniquely ID a device. You could take 200 phones with same model etc , but as with radio fingerprinting, it's unique to each phone.
Edit, most rfi for radio fingerprinting a device is under 1mhz, and at these long wavelength/low frequency, that rfi travels very far, with miniscule power required
