Sorry for my 2 day of absence, my hard disk just died.
Weel Kolofai, i didn't installed. it is my "Lebeau vitres d'auto" dealer who installed it four years ago. So it would be very hard for to tell you what brand it is and how it is installed sorry... Wow, just got a brilliant idea, just phoned where they installed it and they still had all my info in their computer...
So, it is a "Astro Start, model # 1105.
What I can tell you about it is
The stock lexus alarm still work perfectly and very transparent.
It start every time when close (125 ft)
but when further like 500 ft, it depend where i am park, sometime 2-3 parking place
further or closer, on the right or the left will do a better job. Test done at my job parking lot.
It also unlock the door and the trunk.
And a panic button that make play the horn for positionnning your vehicule in large parking lot.
There is also a button to lock the door and arm the alarm.
A friend of my who had a cheaper model in is car (just start and shut up) didn't had any problem with where the car was park : all the spots I had problem remote starting, he didn't have any problem. hic
