You are right as how many time have people let some locksmith to try to impression key for there lock. As for some they don't know how to impression any lock as they do go way to far by trying to take the whole lock apart as thinking they can make a key found out they can't. They end up destory the whole lock. It going to be hard to find some old timer that do know how to do this better than most new locksmith today. As today locksmith they only want to cut key by code to get a working key. This is why I tell most people as be careful of how or who you deal with some locksmith....
