I read in the manual and the iphone app that you should be able to modify the unlocking of the doors to be 1 push for both doors instead of the 1 push for the driver then another push for the passenger. The iphone app says to hold down the lock button for more than 4 seconds, then hold the unlock while still holding the lock button, then release them both together. I have done this numerous times with no change. I have done it with the doors unlocked and the doors locked with no change in outcome. What is the trick?
