L2,000 is a lot of money for a three week locksmithing course.
Before enrolling, ask to see a course outline and speak to graduates from a couple of years ago to see how they fared after completing the course.
The big problem with a very intense course like that is information overload.
You should be comfortable working with common hand tools and portable power tools before signing up for an intense course like this one.
You also want to know just what the course objective is.
e.g. to be able to install, repair, repin etc pin tumbler locks including those in a three-level master key system, or to also install, diagnose and repair card access systems both stand-alone and those using a central computer.
In addition to lock assemblies, locksmiths deal with exit door hardware (crash bars) of various types, electric strikes like apartment front doors often have, automotive locks, safe deposit box locks including drill-outs; office equipment and furniture locks; small safes (fire and money); jail locks; and high-end luggage locks to mention only some of the locks you may run into on the job.
Unless you specialize in safe work, you probably won't be working on large high security vaults as used by bankers and government.
In short there is an awful lot to know about locks to make you a well-rounded locksmith and three weeks is an awful short time to learn it in.
I suppose it can be done, but be prepared to work your butt off and eat, sleep and dream of locks and related hardware.
There are also alarm systems that locksmiths install from time to time and they can vary from ones that just sound a siren to ones that signal into a central station of an alarm company which calls the fire brigade or police etc.
Mind you, serious alarm systems are generally installed by specialists in alarm systems who work for major alarm companies such as Chubb, ADT, AMPATROL, Burns and the like.
Alarm installers and repairmen are not necessarily locksmiths and locksmiths are not necessarily alarm installers.
There are also survelience cameras and video recorders and even things as mundane as key stations for a watchman's DETEX clock.
Hope this gives you some things to consider before parting with 2,000 pounds Sterling for a three-week course.
