On many vehicles with electric locks, you cannot lock the doors (even with the remote) with the key in the ignition. On all my Fords, I can leave the key in the ignition, open the passenger front door, and use the lock button to lock all doors. I gain re-entry to the vehicle either by using the remote or the remote key pad on the driver's door.
