looking for an alarm

Hi everyone, I have been in the market for a new 2 way alarm/remote start.  What I really whant is the feature that disarms the alarm and unlocks the doors as I near rhe car.  I found one "Performance Teknique ICBM-7071" this would be alright except I cant find any info about the company.  Does any one have any recomendations?  Are there any other systems that have this feature?  I would like to get a good system not a cheap off brand one.  Thanks in advance :)

I actually just didn't install it at all because in CA, I hear that if you have a manual then you're not supposed to have remote start.  Personally, I didn't install it because I heard that a lot of people have had problems with their car with the remote start installed so I just stayed away from it entirely.

jc18750, since you installed Matrix then maybe you can answer this question for me.  I had my Viper791 installed by a shop and everything works but when the hood goes off, the remote is indicating that the trunk has been breached, not the hood. So I called the shop and the guy said that the reason why that is is that both the trunk and the hood share the same line/connection. So even if the hood is breached, because there is only one line going in, it reads trunk on the remote. Is this true?  Since you installed a couple then you would know about the connections and how they enter in.  Thanks bro.
