Keystone Auto Parts does not operate any physical retail locations, but instead works with a network of salvage yards across the country to source various car parts, as of 2015. Its website, KeystoneAutoParts.info, allows you to designate an exact part for a specific make and model vehicle and submit a request for it to the company.
Keystone Auto Parts is a used car part location service that does not maintain its own inventory or any retail centers, functioning only through a Web interface. All of the parts it sells come from different auto salvage yards, which house an assortment of vehicles with salvage titles from which the parts come. A salvage title vehicle is one that experienced enough damage in an accident that its insurance company determined that its potential resale value did not justify the cost of making the repairs. As such, salvage yards purchase the vehicles and sell the individual parts for use in other vehicles.
The Keystone Auto Parts website features tools that allow you to choose a car make from a list, then navigate through a series of options to choose the specific model and year to find a list of its different internal and external components. Once you choose the part, or parts, that you need, you are able to send the request to the company so that it may locate the part at one of its salvage yard partners.
