Alarm system using stock Key Fob

Title pretty much sums it up. I need to find an alarm system and I would really really prefer to have a system that goes through the stock fob and I was wondering if anyone know of/have any systems?

 

I've never ever heard of this. I'd say not possible, but I'll subscribe to this and see

 

Hmm, it's an interesting idea. I'm guessing it would have to be customized to the same frequency of the key fob in order to work, which could run into $$$.

I'll keep an eye here and see what people come up with, I could use the same on my truck. Sorry I can't be of help!

 

All the new Viper alarms all use some kind of encrypted roaming code technology that is unique to them, not compatible with their older models which don't use this. So it probably isnt even something where you just transmit on a specific frequency like you are saying, since it is digital etc. also the antenna must be completely different because on my Viper I actually did get it to unlock over a mile away when I was out fishing on a huge lake and could see the parking lot off in the distance.

 

What you want is commonly referred to as a "slave alarm."

Viper makes a decent one.

Looks like this should work
