IMPORTANT, please include your Vehicle Identification Number (VIN number) with your order to insure that we match up the proper ignition switch for your vehicle. This lock works for both transponder and non-transponder applications. You will need to add transponder chip keys (from our other listings) if you have a transponder application. You can also have this lock re-keyed to your existing locks through our locksmith division or at your local locksmith. This item requires a locksmith, mechanic or someone with mechanical ability for installation. New transponder keys will require programming to your vehicle.
