Frequently Asked Questions
How do I provide my VIN?
You can add your 17-digit Vehicle Identification Number (VIN) in the notes section at checkout or simply reply to your order confirmation email with it. We cannot program and ship your module without the VIN.
Is this a difficult part to install?
The physical installation is straightforward for someone with basic mechanical skills. The ECM is typically located in the engine bay, under the battery tray. After installation, you will need to perform a security relearn procedure (often called a ‘key relearn’ or ‘anti-theft relearn’), which can usually be done without special tools. Instructions can be readily found online for your specific model.
