How do you like to become a locksmith ?

Here in the United States, they usually make a copy of the state id of the individual requesting the keys.. then it turns out to be a criminal the locksmith can report it.... They also in many cases will request permission from the owner themselves it it turns out to be a car, or a property the person clearly does not own... As far as turning down business from an gangster that is a risk that many jobs run.. in those cases the best you can do is get their identity give your services and immediately report them as they leave... Most Illegal crime rings have their own people to do that and are not going to be brave enough to go to someone that is not a member for that sort of thing... I thought locksmith would be cool too.. But this is not to say that sometimes people do not trick locksmiths or others into copying keys.. in some cases locksmiths save photos of all the keys too as their are codes on the keys as well... in many cases.. But there will be situations when you really do not know, like if someone is housesitting or even babysitting for a relative out of town borrowing their car, and locks themselves out. or out of the house even... But most of the time.. they find out when the owners are going to return, or have a contact number for them they can give the locksmith so they can call and verify the person is indeed allowed to be there at the time.. in other cases.. I have heard locksmiths write down their information and when they are going to return and then call the owners to verify that it was legit when they return if they do not get that verification then have some law enforcement show up to do a check asking questions. I am not sure how that is all done in Hong Kong but these are things I witnessed done here in Wisconsin, USA.
