We never know what causes people to commit a crime. However, the risk of being robbed by a locksmith is the same as that of being robbed by a normal thief. That's why it's so important to keep door and window locks in proper condition and to use only professional and trained residential locksmiths. It depends on state locksmith regulations.
However, if the safe is in the burglar's house and there's no reason to suspect, the locksmith will generally trust the apparent owner. United Locksmith is an experienced locksmith company that provides excellent affordable security service across the country.
