Hello, I just bought a 2013 LR4 HSE. My question is- is it possible to lock the doors while the car is running? The truck I just traded in was a Ford F150 Platinum and I was able to leave the key in the ignition, running, take my spare set and use the remote button to lock the doors. This is super handy in my small town where I'm not worried about anyone busting out a window and taking off with my car! I have played a little with the smart keys and locks but can't seem to get this to happen; however, I'm still learning with the whole smart key thing. Any insight would be helpful, THANK YOU!
