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

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

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.

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.

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.
