Service keyless start system comes up when I start my vehicle

[don penney]

Hello, I recently installed a brand new center console in my 2020 chevy silverado 2500HD. It didn't come with a theft module, so I purchased a new one and installed it under the cup holders. But now I get the message every time I start my truck. And my door press locks do not work. And my remote start doesn't work. Any ideas would be great. I do have an appt at the dealer on Monday for this. But would love any ideas.... thanks Don
