In several states in America it is required by law that locksmiths and locksmith apprentices acquire a license before trading as a locksmith. This is because a locksmith is seen as a profession that directly affects the safety and security of the public, so trading as a locksmith in these states without a license is against the law. With these states it may be a requirement that you sit a locksmiths exam before being granted your license and will generally run a background check to see if you've any convictions. They take giving the trading licenses so seriously because of the public safety factor, and at the end of the day if you don't complete the job properly you could be making the persons home unsecure.
To obtain a license, you must find out where the local locksmiths licensing office is and purchase your license. However you must also check for laws and regulations regarding the practice of it before you do so. This is because each state that enforces this law may have different processes to follow.
You must also present many forms and credentials in order to obtain the license, since handing out the license to random people wouldn't exactly be prudent. So to get your locksmith license you must gather up the proper forms, and then send in your application along with any fee's they may charge. It's important for you to find out the exact information you will need to give the office, because there's little point in you sending in your application before gathering all your information together.
There are a few types of locksmith licenses, and depending on the state, different regulations on how to handle them. Here are some types of licenses; apprentice locksmiths license, training license, masters license, and a teachers license (for those teaching an apprentice). Each of them have different regulations that you must abide by, unless your license will be revoked. In some states you have to renew them after a certain period as well, so be sure to remember when they're supposed to be renewed. You must also be sure to keep your information up to date with the registering bodies so there are no mix up's further down the line.
