How to clear CX-5 Keyless system Malfunction error?

Due to a logic glitch in my new Compustart remote starter and my 2018 CX5, I ended up in the end, unable to start my car even after removing/resetting both battery cables (5+ minutes) per installers suggestion. Once I got a battery boost. Systems in the car came back on and started up. However, I'm now left with the Keyless Malfunction error showing up in the display. I tried the "open the door & hit unlock button on the fob" and I got the door lock cycling like it predicted. It didn't get rid of the message. I also tried my spare fob (which needs a new CR2025 apparently). Any good suggestions on how to clear that error out?
