lately ive noticed that people have been takin a serious notice to my jetta (prob cuz its all done well and lots of money put into it0 anyways about a month ago my car got keyed from headlight to taillight rite throu the paint then the other nite i noticed my hoodpins were unlocked on my carbon fiber hood. so it gets me wondering bout car safety...i got a stock one already but obviously it didnt go off when they keyed it so now i want a new one...i hear everyone talkin about the viper 791xv and its remote start/sensor etcetc stuff well i want one but i wanted to know how sensitive it is to goin off like a simple brush on the door and it sets off or wat? and will it go off if someone drives by with there subs blastin?

If someone keys it i dont think it will make it go off it took alot for mine to go off. I think you can always change that though.

You can install a DEI 508D dual zone radar proximity sensor and adjust it so if anyone gets close it will go off. 1st zone is a "warn away" which will just chirp the alarm and if they stay in the zone or get closer it will trigger a full alarm.

From the DEI website:

DEI 508D is the most effective vehicle intrusion sensor. This dual zone radar sensor detects moving high density objects using RF field-disturbance technology. Ideal for convertibles & t-tops or any application where zone intrusion protection is desired.
Contains a new custom chip for outstanding stability. This is a great way to give you vehicle that added protection from would be thieves and vandals!
Leave your windows or top down without compromising your vehicles security with the DEI 508D . It will work for just about any alarm system.

It will interface with the Viper 791xv pefectly.

Here is a link to the owners manual.


I know somewhere in there it tells you everything you want to know.

PM HCCAfan here on the forum and see if he can still get the Viper alarms.
I got mine from him.
As for as the sensors go I'd check on eBay.
The remote works a long distance depending on if you are inside a building or line of sight.

Hope this helps!
