I was going to post this, but did a little more digging and found the answer. Now will post this for the benefit of others

Could someone tell how to change my fob back to how it was? It had been 1 click to unlock the driver door, two for all 4 doors and tail gate. All was OK then one day, one click started unlocking everything.

Thanks for any help.

"Unlocking the Vehicle (Two-Stage Unlock)
Press the button to unlock the driver door. Press the button again within three seconds to unlock all doors. The direction indicators flash. Press and hold both the lock and unlock buttons on the remote control for four seconds to disable or enable two-stage unlocking. Disabling two-stage unlocking allows your entire vehicle to unlock with one press of the button. The direction indicators flash twice to indicate a change to the unlocking mode. The unlocking mode applies to the remote control and keyless entry keypad. Intelligent access at the driver door will unlock your entire vehicle when you disable two-stage unlocking."

Congratulations. Now you have it set where it should be.

 

I love the 1 click unlock all doors. On other cars when you get home and have things in the back or passenger side you run out to get it and only the drivers door is unlocked. Hate that.

 

Is there a way to set truck to unlock doors when the door is opened - for example, when I open the drivers door, I want the passenger doors to open as well. I've looked to the FORSCAN thread and Googled it, not saying I've missed it but I didn't find anything...
