Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.

I was really impressed with how straightforward the installation was on this ECM for my 2016 Silverado. It came fully programmed to my VIN, so I just had to plug it in and everything worked perfectly right away. Shipping was quicker than expected, and when I had a quick question, their support team was very helpful and professional. Overall, a smooth experience that saved me a lot of time and hassle.
