Frequently Asked Questions
What is VIN programming and why is it required?
VIN programming is the process of loading your vehicle’s specific software and calibration files onto the ECM. This is essential because it allows the module to communicate correctly with your car’s unique set of options, engine type, transmission, and security system. Without it, the vehicle may not start or run properly.
Do I need to do anything else after installation?
In many cases, you may need to perform a security relearn procedure (also known as an anti-theft relearn or Passlock/Passkey relearn). This is a simple process that can typically be done without special tools and involves a sequence of key turns. This syncs the new ECM with your vehicle’s anti-theft system.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is a required step.
