If I'm thinking of the same ones the parent comment was thinking of, then the key is only removable by the carrier. Of course, if you get a package, you can always copy the key while it's in your possession.

That said, no solution will ever be foolproof. If the attacker wants it bad enough and has physical access to the locker, they'll be able to get to your package. Whether it's copying the key, cracking the code, picking the lock, or just tearing it open. With enough determination, your stuff can get stolen. It just becomes a legal matter at that point.

yea a safe alone is not a secure method of store. It's just matter of time and safer methods only delay opening more. It's still a good tradeoff in my opinion between privacy and secure storage.

The vast majority of packages don't need extreme security.

Personally I don't care about security of my packages at all—they just sit outside my door for me. If one is lost/stolen, Amazon will happily replace it.

Anecdotally, I've had a phone delivered to me but my neighbour took it in fearing getting stolen and then later gave it to me after I've reported Amazon as not delivered by due date and carrier has confirmed having delivered by the door. This was in apartment setting so everyone was acting reasonably. Amazon ended up shipping me another phone and I ended up with two phones. I think I just prefer the idea of things getting delivered with determinism and security--just so that it saves everyone time and effort. I may be a bit paranoid about this.
