Hey,

My car just got broke into, that thieves stole my GPS and credit card.
I just sent my car to the dealership to get a window replacement.
Now I am thinking to upgrade my factory alarm by adding something with shock/ultra sonic sensor. I have found a few options but I do not know how good the product is. I would like to know any tried it before? Or what everyone think about that upgrade system?

It is call 3901T OEM Security Upgrade System
Here is the link to that product website.

and here are the Manual

These are the other module I found.
Viper 3901V OEM Security Upgrade System
http://www.xpresskit.com/product.aspx?prodid=3901V

Looks like all of these are from the same company..

So which one should I get? and are they reliable? or good?

btw, the reason I want this because I want to stick with my FAST key, and do not want to get 2 remote out all the time.
Thanks

 

Caring two keys may be annoying but i have found that viper is the best working alarm there is. Unfortunately it isn't an add on. But you cant put a price on great security. Just my 2 cents.

 

sorry for my ignorance, but if windows are broken do our alarms not go off?
under what terms will our alarm go off? i too am thinking about the viper. Two of my friends had them and they were great.

 

what is the model number of that viper u are saying?

 

Get one of these two..Viper 5701 LE or Viper 5901 ..I cant decide yet

 

i really do not want to replace my factory alarm, i want to get a by pass or upgrade to the factory...

 

Go with the 3901T, that is what I would use if you want to retain the factory FAST key ONLY.

 

Is there a reason why you dont want to replace the factory alarm?

 

compustar pro 9000 the range is awesome and it will alert you even if a large vehicle passes by its just right for sensitivity and comes with great features

 

3901t is actually a cool system!! check this add on unit for it...
