How to Get Your Unit Rebuilt

To initiate the process, please complete the form on our website (Submit a new order). Once you provide the necessary information, we will contact you via email with your mailing authorization number (ID) and shipping instructions to our facility.

Test and Repair

Each part undergoes thorough testing on our bench both before and after repair to ensure optimal functionality.

Turnaround

Most orders are completed within 24-48 hours, but complex repairs may take longer.

Warranty

All of our products and services come with a 1-year warranty and unlimited mileage. If you provide your own used part for programming, please be aware that we cannot guarantee our services or offer a warranty.

Programming & Coding

During the repair process, we do not alter the original programming and coding. When you receive your unit back, you can simply plug it in and start using your vehicle immediately.

Remanufactured vs Used

We recommend repairing your electronic module rather than purchasing a used one. A used module may be nearing the end of its lifespan or could have the same issues as your current one. Our repair service utilizes upgraded original components that meet or exceed manufacturer specifications, ensuring a more reliable and durable solution for your needs. If your part is not repairable, we will inform you and offer the option of programming our refurbished original manufacturer part that we have in stock, which also comes with a warranty.
