Re: Is this method of Locking yourself out universal?
The reasonable assumption is that if you press the FOB to lock the doors while inside, you'll have the FOB in hand and won't forget it inside like you might by using the door lock buttons (or if a passenger hits the door lock button like what happened once with my WK Limited with it running...got locked out). Seems a reasonable design to me.
