I got the info from DEI directech diagram. They say the only way to disable the alarm is by remote only. I believe 06+ models are all the same because they have immobilizers. This makes it really hard to integrate DEI with the factory alarm, and I probably have to carry around 2 remotes to get it to work. SO, I abandon the idea of having one for later when I dont get so lazy.
It probably would be cleaner if we can remove just the factory alarm
and replace it with a DEI alarm with remote starter integrated unit so that way, we can have 1 remote for everything. And also integrating the DEI with the immobilizer wouldnt be hard.
