To stay away getting scammed
To stay away getting scammed by a locksmith, here is one thing that you can do: Find out if the company or person has a physical address or a retail location. It is said that about 92% of the locksmiths than you can find on the search engines do not actually exist. In fact, its really difficult to find one near your town if you only search via the Internet. So, if you really want to deal with a legit locksmith, better call those that you searched over the web and ask for their retail location. If they cant give you one, then dont hire them.
