Practicing Locksmithing As A Profession is a Crime for the Unlicensed.
As all reputable Locksmiths know, you must be licensed by your state to be employed as a locksmith. One must pass criminal background checks by the Federal Bureau of Investigation (FBI) and the Department of Justice (DOJ). If caught practicing without a locksmith license, you could easily face hefty fines and jail time. Even the possession of lock picks and other locksmith tools can be seen as criminal if you are not a licensed locksmith. The tools used by a locksmith are viewed as burglary tools by many states. Unauthorized possession of these tools can also lead to felony or misdemeanor charges. Most, if not all locksmiths know this. But this is also a word to the wise for the lock picking hobbyists out there. Be careful where you bring your tools, you may have no criminal intent but law enforcement officials may see it differently.
For example in California, one can get a ten thousand dollar fine and up to a year in prison for providing locksmith services while being unlicensed. Most states have similar laws, so it would be wise to research the laws of your state.
