It's not a good idea to have the decision making happening on the outside of the door you want to protect. Ideally, the outside component should just be the antenna and the microcontroller should be on the inside of the door.

As they demonstrate in the video, you can open their example case with a screwdriver, so then you could either short some connections to release the door lock (if it's self-contained), or connect to the ESP to grab a copy of its firmware and configuration to connect directly back to whatever controller it talks to over wifi (if it's part of a larger system).

Bypassing the system is not completely trivial, but for a determined actor, possible. For outdoor or higher security installations, two boards are recommended, where the outside one acts purely as an antenna.
