You will first need to decide what kinds of vehicles you want to work on before you can become a vehicle mechanic. The steps to become an automobile mechanic, for example, may be different than becoming an aircraft mechanic, so you will need to research the fields in which you are interested and find out what level of education you may need. Most automobile mechanics only need a high school education and some job-specific training, and some aircraft mechanics may also need just a high school education. Other types of mechanics, including some aircraft mechanics, may need a higher level of education and training.
It helps to become a vehicle mechanic by starting early: in high school, take automobile maintenance and repair classes if they are offered, and if possible, do work on your own automobile to become familiar with the functions of the vehicle. Working at an automobile repair shop is a good way to get the training you will need to become a vehicle mechanic, even if you are only working as a parts runner or counter help. You will be able to develop a relationship with the company, which can pay off in the future if the company is willing to train you to become a vehicle mechanic as you work for them.
Many automobile repair shops prefer to hire mechanics with certifications in repair. Automotive Service Excellence (ASE) certifications are preferred by many repair shops in the United States and other countries, so whenever possible, try to earn these certificates to become a vehicle mechanic with attractive credentials. Community and technical colleges may offer courses on automobile repair, and you may be able to obtain some of these ASE certifications by enrolling in such courses. Remember tuition costs can add up quickly, so draw up a budget before enrolling.
If you are interested in becoming an aircraft mechanic, you may want to think about enrolling in college courses that will cover the topics necessary to become a vehicle mechanic in this field. The military can also train you to work on aircraft, though in most cases, you will need to make a commitment to the military for several years before you can work in the private sector. Be ready for such a commitment if you want the job training without having to pay for college classes, and be sure you can handle the other responsibilities of being in the military.
