Beware of Phony locksmiths!

Phony locksmiths also known as "scammer" locksmiths, advertise as an "unlocking service".  They do not post credentials such as a locksmith license.  Nor do they possess the skills of a true security professional.  These scammer companies are famous for quoting a low price on the phone and doubling or tripling the price after they have your keys in their hand.  Always ask a company advertising as a locksmith for their license number.  The license number can be verified here:
