Command start CS-580i FM

[project]

I have a CS-580i FM remote start alarm system that stopped working. Does anyone have any troubleshooting experience with this type of system. The Remote seams to work but the car will not respond. I have tried both remotes (2 way & 1 way) with no luck. Any information would be greatly appreciated.

First thing to check would be the antenna connections at the unit and at the antenna on the windshield.
From there I would check power, and ground to make sure connections and fuses are good.:thumbsup:
