Upgrade alarm to 2way?

Is this possible?

I don't understand your question, what do you mean by 2way ?

Its when the car sends a feedback to your key saying why your alarm was activated and provides more options

In the UK these systems are usually aftermarket fitted often in a package with satellite tracking. The "old" Land Rover Watch system operated this way but unfortunately it's no longer available as the monitoring company went down the tubes last year!
