Technically, no. There is no government body that sets the standards for the locksmith trade, unlike plumbers and electricians. There is a course run by companies that have a college accreditation but there is only so much you can learn on a course in one week. Locksmithing is a trade where you are constantly learning, as new locks are always coming on to the market.

It depends on what work needs to be carried out and at what time of the day. The labour charge is the variable. The labour charge at 3 pm is a lot cheaper than the labour charge at 3 am.
