well i got the new viper with the 1 mile range. obviously living in NYC, i knew that i wasnt going to have 1 mile range. the one mile is out in the desert with a clear shot. but i was rather disappointed with its lack of range in the city. while waiting for the bus 4 blocks from my house, i tried testng the range of remote. i pressed unlock about 4 times and then was able to unlock my car. i then tried to lock my car but it took me another 6 tries before it locked. i also had to raise the remote in the air to get the most range.
thats not all. sometimes when im near the car, (3 ft away) and i would press lock/unlock, the responder would beep 3 times stelling me no reception. i would think that being 3 ft away, the responder would work 100% of the time.
with reception like this, i dont know how reliable the alarm is now, even if my car is parked in front of my house. the remote start is still useful tho.
