I'm coming to you guys for everything moving forward.
I am very happy with 9921 MT remote it is working perfectly.
Got it with in days installed it and worked fine.
I accidentally purchased a 9921MT when I needed a 9931MT. Gatehouse was very good at the RMA process and I got the correct part quickly.
