A Locksmith receives certification after passing a written exam. Currently, there are 36 categories on the exams but only 10 of them are required for the most basic locksmith certification. These 10 required categories include: codes and code equipment, cylinder servicing, key blank identification, key duplication, key impressioning, professional lock opening techniques, lockset functions, lockset servicing, basic master keying, and cabinet-furniture-mailbox locks. The other categories are specialties in locksmithing such as foreign and domestic cars, safes, and installation practices.
If you need a locksmith for a common purpose, such as helping you when you get locked out of your house or rekeying a lock, then the most basic locksmith certification will generally suffice. If you are dealing with a high security lock or new car locks, then you may need a master locksmith which specializes in your purpose.
Regardless of why you need a locksmith, it is important that you ask what certification he/she has and where the certification is from. You shouldn’t trust your locks with just anyone! By choosing a certified locksmith in your local area, you can trust that the job will be done correctly and you are getting an expert tradesman dedicated to the job.
