If you’ve ever locked yourself out of your car or home, you know what a hassle it can be. Your first thought is to get someone to help you out of your situation. If a family member or friend can’t deliver a spare set of keys, your next call might be to a local locksmith. But before you make that call, consider this: According to the Federal Trade Commission (FTC), the nation’s consumer protection agency, some locksmiths advertising in your local telephone book may not be local at all. They may not have professional training. What’s more, some of them may use intimidating tactics and overcharge you.
