Hey I have an '04 landrover discovery II. A couple weeks ago my front passenger door stopped unlocking (with key fob and central button) and to open I'd have to reach over from the driver's seat. I woke up and now all of my doors are locked and unable to be open from the inside.
JA: Have you checked the fob's battery?
Customer: I switched the key battery recently and the key fob still locks the driver's door so I don't think that's an ossue
JA: Are you fixing your Discovery yourself? What have you tried so far?
Customer: From reading on forums they said to check the fuses and also try putting the key in and unlocking and holding the key in the unlock position for 3 seconds but that hasn't worked and all of my fuses were fine
JA: Anything else you want the mechanic to know before I connect you?
Customer: Well I am thinking that maybe when my passenger door lock motor died it put the disco into superlock mode. I'd like to know if maybe that sounds correct and how I could go about disengaging the superlock mode and opening the doors to replace the door motor/latch system.

Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.

Do you understand wire diagrams and volt meter usage?

Here is your wire diagram

Step one is to check all the fuses related shown at the top of page one.

Next we need to OHM test the YE/PK and PK/RD wires from the lock switch to make sure those wires ground when commanded.

If those are good then we need a scan tool to see if the BCM is getting a lock and unlock signal and sending it out.
