I don't have a remote starter, but if the engine doesn't shut off, can you drive off without your key? Does the engine stay on until you get to your destination?
That's exactly why, that aftermarket remote starts won`t shut the truck off after opening the door, the ignition usually will shut off if you step on the brake before putting key in the ignition, the factory remote starts usually suck, I worked for Toyota for many years and every truck I bought got an aftermarket remote start
^ this is how my Compustar remote start/alarm works..
The factory remote start not only shuts off when you open the door, the range on it sucks.
I was very fortunate to have a Toyota salesman honest enough to talk me out of the factory remote start and recommend ANY aftermarket remote start.
It doesn't make sense to have to start your engine twice..
And with certain aftermarket systems you can use your smartphone to lock, unlock, start, and stop your engine from anywhere.
I can punch out at work, start the truck, and have it heated or cooled by the time I get to the truck.
I can start the truck, even if the valet has the keys, and get it heated or cooled before my bride and I get in.
Easy to tell the valet, "it will be the one that is already running"...
We valet park a lot...
I don't know how the stock remote start works, but if I remote start my truck, it starts a 15 minute timer to keep running and shuts off if I don't get to it in that time..
My remote has a range of 500 feet, unlimited range if i use my iPhone...
