It almost never ends well. Modern vehicles are complex networks, and the ECM is the central hub. Without the correct VIN, security keys, and option content (like transmission type or emissions equipment), the module simply won’t work. You’ll face a no-start condition, persistent error codes, or even damage to other electronics. Our service eliminates that risk entirely. By providing a **Programmed 12635019 ECM**, we’re not just selling a part; we’re delivering a proven, reliable repair that works the first time. ### Frequently Asked Questions **What information do you need from me?** After you place your order, we require your 17-digit Vehicle Identification Number (VIN). This is essential for us to load the correct GM-certified software and settings for your specific vehicle configuration. **Do I need to have a mechanic install this?** While installation is straightforward for those with mechanical experience, we always recommend professional installation. After the new ECM is installed, a security relearn procedure (often called a key relearn or anti-theft relearn) is typically required. This procedure can usually be performed by the owner and does not require a scan tool. We can provide instructions upon request. **What is the special process for Camaro and LaCrosse models?** For the 2010-2011 Camaro and LaCrosse, the immobilizer (anti-theft) information is stored uniquely within the ECM. To ensure a true plug-and-play experience, you will need to send us your original module. We will expertly transfer this critical data to your new **Programmed 12635019 ECM**. We will contact you with shipping instructions after your purchase. **How do I find my part number to confirm compatibility?** Your original ECM will have a sticker with the part number on it. This unit is a direct replacement for part numbers **19300015**, **19300014**, **12617230**, **12636355**, and **12635019**. However, our VIN programming ensures compatibility even if your number differs slightly, as long as your vehicle is listed. **Is this a brand new part from the dealer?** This is a quality-tested, verified component that has been meticulously inspected and prepared to meet or exceed original equipment standards. It is then loaded with the latest vehicle-specific software from GM, providing a reliable and effective solution. Please enter it in the payment notes and save to ensure we receive it. Orders without a VIN within our 2-business-day handling period may be canceled, as programming cannot proceed without it. ### Shipping - **Processing Time:** Reliably shipped within 2-3 business days. ### Warranty Enjoy peace of mind with a **one-year replacement warranty** on this part, effective from the date you receive it. Labor costs are not covered. If the part fails within the warranty period, we’ll replace it with a comparable unit or refund your purchase price, ensuring a hassle-free experience. **Return Address:** **Highway71autoparts** **9131 Highway 71 NE** **Spicer, MN, 56288**
