Just put in an astrostart remote start last week and love it. I was very weary about having an aftermarket key fob in my pocket just bc im anal about it looking stock. From the short time if had it, I can def say I wont own another vehicle without haveing it.
If you go aftermarket you can do anything you want along with a combination of things.
For example, I have remote start with a 5 second delay. I can turn my heated seats on, turn defrost on, roll windows down, and vechile locater. It can be set up to roll all four windows down, 2, or 1 or whatever youd like. A two way remote is definately the best, bc without you never know if the remote actually made the connection from the signal for the vehicle to do exactly what you want it to do. With a two way it will chime at you if the truck started, stopped, turbo timer, if the seats were activated. Plus I have just under a mile of range. You can get an app through a bunch of different remote starts to control your vehicle. You pay for installation and such and they tell you app is free, BUT catch is you have to pay a monthly or yearly fee for the program to be able to run it. That is your choice if it interested you or not. I wasnt that into it bc I dont want have to be trying to pull out my phone all of the time to start my truck keys just seemed easier to me.
