Modules and electronics are not "defective" if you are unable to program into your vehicle.
In the event that a module is defective, we require proof from your mechanic, stating the module is defective as well as the steps performed to determine the module is the issue. All electronic components we sell will have a “Warranty Void if Removed” seal and or Thread Check Paint on the item. If this seal or paint is removed, ripped, or damaged, the item cannot be returned for a refund. Removal of this seal or altering an item voids any reason for return and will not be refunded
