The only problem with the remote start is --- it works poorly on days with y's in them.
My remote start works great for stock remote start it work very far away. I have a buddy that had the two way LCD after market remote start and mine work as far as his does. This is what the manual says about the remote start.
To remote start your vehicle, press and release the
“Remote Start” button on the key fob twice within three
seconds. To indicate that the vehicle is about to start, the
parking lights will flash and the horn will sound briefly
(if programmed).
Once the engine starts it will run for 15 minutes. To
cancel remote start, press and release the “Remote Start”
button once.
To enter the vehicle while the engine is running during a
remote start, you must first unlock the vehicle using the
“Unlock” button on the key fob. Once the vehicle is
unlocked, you have 60 seconds to enter the vehicle and
insert the key in the ignition and turn it to the ON
position. Otherwise, the system will cancel the remote
start and automatically turn off.
Remote start will also cancel if any of the following occur:
1 If the engine stalls or RPM exceeds 2500.
2 Any engine warning lamps come on.
3 The hood is opened.
4 The hazard switch is pressed.
5 The transmission is moved out of P (Park).
The vehicle can be started remotely a maximum of two
times consecutively. The vehicle is also allowed a maximum
of one failed start, where the remote start sequence
was initiated but the engine stopped cranking without
starting. Following either of these conditions, or if the
Vehicle Security Alarm (if equipped) is alarming, or if the
PANIC button was pressed, the system must be reset
before remote starting the vehicle again. To reset the
system, insert a valid key into the ignition and turn it to
the ON position and then back to the LOCK position.
