Last December, I had the Viper/Python SST Remote Start/Alarm installed on my Avalanche. It worked fantastic for several months, then started working occasionally? I took it back to the retailer that I had purchased it from, and they IMMEDIATELY said "Bad Remote FOB". I asked if this had been a reported problem, and they said "Oh yeah". This has me concerned. Once the warranty expires (12/28/07) I will be SOL on FOB replacement and these dang things are NOT cheap.......$150 for a fob replacement. Has anyone else had issues with theirs?
