GMC Pickup keyless doorlocks

hi I have a 2001 GMC Pickup with keyless entry. I love the truck.. But one thing makes me curse it to no end.. I have to hit the Unlock button twice to unlock the passenger door!! GRRRRRRRRRRRRRRRRRRR! Does anyone know of a way around this?? I know it shouldn't be a big deal, but I open the truck, drive to a client's to pick up some stuff. Then my arms are usually full of equipment and I find the damn passenger door is locked! ( only the drivers door was unlocked) Then I curse and swear while I juggle stuff the get the door unlocked. GM Note this: If I find another brand of truck that opens both doors at the same time.. I won't be buying your brand again! Who thinks of these moronic things! Its these little pain-in-the-butt things that customers remember most! It should be fairly easy to make both doors open together.. any one know how?

Check your owner's manual, I think you can set it up with a key sequence or something. I know you can disable the doors locking automatically when a certain speed is reached(25 mph?) by following the instructions in the manual

The driver door unlocks first for security reasons. When you unlock it in an unsafe area i.e. dark parking garage, someone could be hiding on the passenger side and hop in and car jack you when you unlock them both at the same time. With drivers door unlock first you can get into a safe area before unlocking the rest of the doors. Its a pain in the butt but their just looking out for you.
