For the past two years I have lived without keys. How? Living in Korea, I have no car. Boom! No car key. Every apartment I’ve ever lived in, in Korea, has had an electronic keypad lock. They’re really convenient and safe. Need a friend to stop by and water your plant? You don’t need to make a second key, just give them the code. Worried that someone knows your key code that shouldn’t? Just change your key code.
