Frequently Asked Questions
What is VIN Programming and why is it necessary?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the ECM.

We handle this for you before shipping.

After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). You can find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
Is this part difficult to install?
The physical installation is typically straightforward for someone with moderate mechanical experience, involving disconnecting the battery and swapping the module. However, some vehicles may require an additional security or key relearn procedure after installation, which can often be done without special tools. We recommend consulting a service manual for your specific vehicle.
