A lawyer can become a locksmith in a few months (weeks? days?). If the flip mentioned is really happening, isn't it temporary?
Can you pay for ad placement on Google Maps and answer locksmithing calls? Yes, probably. Can you join all of the professional circles needed to access all the manufacturer data, parts catalogs, etc. ? Not so easily, I'd bet. I would hope that not just anybody can pay a fee to a safe lock company and get the manufacturer's code, for example.
