I just tried my door key and it didn't work, so then I tried my other key and it also didn't work, so then I tried the first key again and it worked.

So in conclusion, my front door is apparently now part of the USB standard. 

 @b57999c7 @88dcfa17 Time to upgrade the door to USB-C. 

 @b57999c7 I have the same problem when I drink. I conclude that it's a USB 6.0, with an AI built it.
