My other thought relating to what you said would be why on Earth does a door lock need Linux? This is not exactly a massively complicated device, it controls a 2-state mechanism and needs to work at about a five foot radius. The fact that something like that, in an IoT mindset, needs an entire webserver is ridiculous. This is much more suited to a micro-controller with custom firmware and a tiny attack surface. No, maybe you won't be able to set it up with a smartphone and 2 minutes, but it also might WORK BETTER if it wasn't able to do that.
