My sister was having problems with the automatic door locks on her 2005 Scion XB. Some of them would work intermittently, others would never work at all. So I went ahead and replaced all the door lock actuators. All the new actuators work fine with the key fob, or the driver's door button. But there are 2 mysterious problems which puzzle me.

1. When using the key in the driver's door, it will only unlock the driver's door. It will not unlock all the other doors, as it should. When I use the key in the front passenger door, it unlocks all the doors just fine. How can I get it to unlock all the doors from the driver's door key-hole?

2. The front passenger door unlocks just fine with the key fob, or driver's door button, but when I try to unlock it with the key, something jams, and when I pull the handle, the door opens a only a little bit, but won't come completely open. I have to push it closed again, lock it, and then unlock it with the fob, or driver's door button. And then it will open normally. Interestingly, if the door is already unlocked, and I turn the key as if to unlock it, it jams, just as previously described. What could be causing this? And how might I fix it?
