I have had this remote for a year and a half or so now. I use to work at a car audio shop and I bought this for my dad because the rep said they worked with the 5900 viper alarms. They do not. lol It has only been opened, and put right back in. Has been in there ever since. Only came out once. These sell for 40 in the stores usually, sometimes more. This works on the SST 160xvl remote starters. They are awesome because of the 1 mile range. 25 shipped, and its yours. BRAND NEW
