Locking and Unlocking all doors with the Key

[ghhubbell]

I just picked up a 2000 Expedition. On my other expeditions if I turn the key to one side the door opens. If I turn the key 2 times one way or the other ALL of the doors lock or unlock. On this expedition the other doors do not respond at all turning the key multiple times one way or the other. The drivers door opens and locks but not the others, nothing. Any help?
Thanks.

I hadn't heard of this before but tried it out on my 1999 with the same result as your 2000.

FWIW, my '011 does the same thing

Haven't seen one that ever did anything but unlock the driver's door ....

Just tried it on my 2000 XLT.
Just a straight mechanical lock driver door only..
