Something doesn't add up about locksmiths...

I'm looking at becoming a locksmith in the UK.

Supposedly you can learn everything you need to know to become a locksmith in a 5 day course. I can't think of another trade where this is the case. It sounds like a scam - is it?

If it were so easy to learn the trade, then why wouldn't an employer just teach you those skills in the introductory period on the job, you know, like every other kind of job...

I've seen people on Reddit say that those courses are shit and that it does, in fact, take years to become a competent enough locksmith to go out on your own to any job.

BUT, there a virtually no locksmith apprenticeships or trainee positions posted online currently.

So someone please tell me, how the hell do I get into this trade?
