There are also keyless solutions to your front door. The second time I had to call a locksmith in Shanghai I got pitched on a combination lock for my apartment door.
That's not to say they make sense. The total amount I spent on having the locksmith let me back in to my apartment that year was significantly less than the cost of putting in a combination lock.
In the western world, where labor is expensive and goods are cheap, you could put in 3 smart locks for the price of one call from a locksmith. I know, I’ve done both.
