Very nice. I wanted to do this if I were to keep my truck longer. My wife's 2015 Chrysler is 100% keyless. Doesn't even have a keyhole in the dash. I love it. Never take the fob out if your pocket.
My wife's Altima is the same way. Call me old school, but I honestly hate it. It has a remote that can be used to lock/unlock the car, pop the truck, and to remote start it as well. It also has the proximity sensors to unlock the doors and open the truck without pressing the remote. The remote DOES have to be within a few feet of the car though, and then you can press the button on the underside lip of of the trunk lid to pop it open, or press the button on the driver's door handle to unlock the door. Press it again and it unlocks all the doors. Then get it and press the brake pedal and push the start button to start the engine. Main reason I hate all of this is because when we go to park, we ALWAYS have to search for the keys. Are they in my pocket, the cupholder, my wife's purse, or her pocket? In my truck, I KNOW they are in the IGN switch and nowhere else.
I sorta like being able to unlock the door and disarm the alarm by pressing the button on the door handles, but I absolutely hate the push button start. I'd rather a keyed ign switch any day.
