While overseas I rented a car and was delighted to discover that it only took one click on the key fob to open all doors and rear hatch. It his been a constant source of frustration that cars I have owned required two clicks. I have a hard time getting the timing right and often have to go through the exercise several times in order to let my passenger in. The two clicks becomes six clicks. Yeah, I'm a klutz.
After coming home I did some research and discovered that many, if not most, new cars have this feature owner settable including my Outlander. All it requires is some careful reading of the owner's manual to find the setup procedure.
The reason I am posting this is that so many believe that changing settings like this requires a trip to the dealer and there are lots of statements to that effect in Internet forums. Read the manual and do it yourself.
