Mechanical! So no WiFi no networking no one is going to hack my dishwasher and have Alexa let them in my front door when I’m not here ! And I can repair it and change the code myself with a screwdriver., let someone know the current code if I need to let them in my house, and I’ll never lose my key and be locked out! LOVE IT.
