Where to find a locksmith:
Internet and printed advertising are common places to find a locksmith. For peace of mind, personal referral is a better choice. When making a decision of whom to pick, choose the one who will give straightforward answers to your questions. Beware of sales talk.
***Please note that some locksmith companies operate out of state. They dispatch local locksmiths that are available in your area. Although it may not be of concern to some people, it is only fair to know as consumers that this is a common practice with some locksmith companies. Often times the backgrounds of these dispatched locksmiths are not checked.***
Get more than one estimate. Have it in writing. Take into consideration the locksmith's expertise, reliability, promptness, and professionalism.
It is your right to ask for a state license. To verify a locksmith's state license, contact the Consumers Affairs at www.dca.ca/bsis. For larger amount of service, you may ask to see if a locksmith has a Contractors State License. To check for Contractors License, you may go to www.cslb.ca.gov.
Avoid bait and switch tactics. Don't be pressured to have locks upgraded when you do not need them.
After completing a service, a locksmith must provide you with an invoice/receipt with description of service done (detailing labor and materials used). Do not forget to ask.
