Whether you lost a key for a General Motors (GM) brand car or truck you currently own, or are in process of purchasing a used vehicle for which the owner misplaced one of the original keys, GM makes acquiring a replacement key fairly simple. All you need is to know the car’s make, model, year and vehicle identification number (VIN).

Step 1

Locate the make, model and VIN of the vehicle whose keys you need to replace. VIN numbers might be on your insurance or registration paperwork. They are also in several locations on the automobile, including just below the windshield on the driver’s side dashboard, on the driver’s side door below the latch, or in the well in which the door latches. VINs are long strings of numbers and letters that uniquely identify each individual automobile and provide additional information about country of origin, manufacturer and year built.

Step 2

Jot down the VIN number for later reference.
