Tips for choosing a locksmith:
What's in a name? Unscrupulous individuals often operate under many business names or aliases. They may answer the phone with a generic phrase like, "locksmith service" or simply "locksmith". If the call is answered this way, ask, "What is the legal name of your business."
Unclear advertising: Look closely at the ad(s) in the yellow pages. Is the specific name of the business clearly identified? Does the ad look similar to other ads but have a different name? Does it appear that the dealer actually operates under several names?
Unmarked car: Some legitimate locksmiths will work out of a car or unmarked van for quick jobs, but most should arrive in a service vehicle that is clearly marked with the name of the business.
Ask for identification: A legitimate locksmith should ask for identification and some form of proof that you have the authority to allow the unlocking to be done. A legitimate locksmith should also provide you with identification in the form of a business card or invoice with the company name on it. Identifying information should also match the name on the service vehicle.
Get an estimate: Find out what the work will cost before you authorize it. Never sign a blank form authorizing work.
Demand an invoice: Insist on an itemized invoice. You can't dispute a charge without proof of how much you paid and what you paid for.
Just say no: If you are not comfortable with the service provider, you can, and should, refuse to work with the locksmith.
