This feature on the Honda models with remote start allows you to walk away from your car and have it lock automatically.
It is especially helpful for those who easily forget little details like swiping your finger on the door handle or hitting the lock button on the inside of your door. Here is how you set it up.
Step one, turn on your vehicle either accessory mode or full engine start.
Step two, from the home menu, enter your settings menu.
Next, select vehicle.
Under vehicle, go into door/window set up and all the way at the bottom you will see walk away autolock.
Select walk away autolock and it will give you the option to turn it on or off. Go ahead and select the on button.
And there you have it, walk away autolock!
