You are so full of crap! You are either seriously confused about many things or are just a compulsive liar.
Show me a Maryland law that says you have to buy the key blank at Lowes to get a key duplicate made.
That first, amazing analysis from a limited data set.
Looking at the Maryland law again, I was incorrect about the jail time. However, the fines are $1000 for 1st offense and $5000 for second and subsequent offense. Re-keying does, as I remembered, fall under the needs to be a licensed locksmith area of services.
A quote from the FAQ page...

2. What services require a license?
Repairing, rebuilding, rekeying, repinning, recombinating, adjusting, or installing mechanical, electrical, or electromechanical locking devices, safes, vaults, or safe deposit boxes; or operating a mechanical, electrical, or electromechanical locking device or opening safes, vaults, or safe deposit boxes by a means other than that intended by the manufacturer of such locking devices.
I've worked at Lowe's in 3 different states, none of which were licensed locksmiths.
There is an exemption, we can rekey locks we sell, at time of purchase. We have some leeway if you have a receipt and the lock has not been installed (like if you buy a lockset for home delivery off our website). We have kits for Gatehouse, Kwikset, Baldwin and Schlage. Some of our locations that sell Tell or Yale will also have those kits. We get $5 per key cylinder, a fee that has not changed in the 16+ years I've been with the company.
That second falls under liability. Why would I cut a key we do not sell, and cannot replace? If we did offer a service like that, there would be some way of charging for it, which there is not.
Also, the new machines we have, if the key is not one we sell, it is not in the system database, which would allow us to cut it.
It is long past the old machine on which I learned to cut keys over 50 years ago, where you clamped the original in one side that had a guide and the blank in the other side that had the cutter.
The newest machine has a camera scanner, a limited database and the function is controlled by a Windows 10 tablet, older machine is similar, but controlled by Windows XP.
The new system (even the slightly older machine that is controlled by a Windows XP tablet) is not as capable of doing non-vendor supplied blanks as even the previous machine with the cartridges that went away almost 2 years ago.
