My understanding is that 'smart' locks also have a physical lock because you need to be able to open them in the event of a power failure. That means that they are, by definition, less secure than a standard lock, because they have an additional attack surface. (physical lock vs physical lock and smart lock).

As anyone who has spent some time doing it as a hobby will tell you, many physical locks are laughably easy to pick if you know how. I would imagine the 'backup' on a smart lock will, in most cases, be added as an afterthought, so will also be substantially less secure than an equivalent priced decent physical-only lock. I'd not be surpirsed if it could be picked by 'bumping' alone, or with a 'master' key, making the lock essentially useless against any professional burglar.

The only advantage I can think of for a smart lcok is the ability to audit (i.e. track) who is opening it, and when. If it's your lock, that's an advantage; if it's a lock that you have to use that does not belong to you (as in this case), it's a disadvantage, and a potentially significant one from the perspective of privacy.

Security and privacy are normally seen as a trade-off (i.e. you sacrifice some of one to gain some of thd other). In the case of 'smart' locks, it seems you are sacrificing both, to a varying degree, for a perceived gain that in most cases is no such thing.
