Without the remotes and knowing how or what was customized (like the toggle switch), it might be easier to remove it and install a totally new security system - if you want one.
About a year ago, the wife and I bought a 98 Suzuki Esteem as a second car (and that way I can have the jeep all to myself
) Anyways, the Suzuki has a Black Widow alarm that the previous owner had in it. It works and has a start disable, but I am hesitant to use it very much. There is only one remote and I don't know where I'd get another one. I tried checking the web and found http://www.blackwidowsecurity.com/
but I don't even know what model alarm it is. I'm afraid the wife will arm it someday and then the remote will die and she won't be able to disarm it, leaving her stranded. We lent the car to my sister for a week and didn't give her the remote. We had a very wet snowstorm one day and my sister accidentally left the headlights on. The battery died and somehow it armed the alarm. What a pain that was for her - snowstorm, dead battery, alarm trying to go off... I don't know how or why the alarm could have armed itself without the remote???
On the jeep I have a Viper and I think it is a much higher quality than the Black Widow. Plus I know how it works and what its supposed to do
If anyone has any experience with the Black Widow one, I'd apreciate any help or links to websites you may know of.
So back to my original point, if you don't know what its supposed to do, and without the proper remotes, I think its best not to mess with it. Or maybe if you contacted the guy he could tell you whats up with it.
