A & B Locksmith is a family owned business that has been servicing the Metro Detroit and Downriver area for over 40 years. These days, things are becoming computerized on a lot of modern vehicles and there is a misconception that you need to contact the dealer to replace your computer chip keys and car fobs. Not true. We can do it, and we offer much better pricing! We use the most up-to-date equipment and stay educated in our industry as the technology is ever growing. We also duplicate all standard home, business and vehicle keys.
