Ordered NewRockies Pro Module fall of 2022 for '02 GMC Envoy. It worked well for nearly 6 months then I started having pass key security issues again. Email NR and they told me what to check. Yup I had not secured one of the wires properly. Bingo I thought! But 2 months later the issue came back - light was on, wires were all secure. Oh no! Tell you what NewRockies is legit! Jack helped me the whole with helpful hints and then with a whole new replace Module. If you're having a pass key issue don't sweat it, buy a NewRockies Pro. They will guide you through installation and back their product. Life is good!
