Well, I don't know what codes the car is giving off. I don't have the SDD. So my options are to go to that mechanic that has the SDD and told me it was both front doors, after telling me it was the rear passenger door, OR go to the dealer for them to diagnose, OR get my own SDD. Not where to look for the last option.

 

Have you lubricated all 4 door latches yet?

Yes. I've lubricated all the latches. Here's what I know...
All 4 doors will manually lock and unlock as designed from the inside. The front doors you can pull the handle and it will unlock the door. The rear doors you must unlock it by flipping the lever, pulling on the door handle does not unlock the door.
The driver door will unlock when I have the fob in my pocket and I try to open the door from the outside.
When try to lock with the black button on the handle (double tap) I get one beep followed by two beeps. The fuel door locks.
When I use the fob, I get one beep. Either way, NONE of the doors lock. Also, the lock/unlock buttons below the touchscreen don't work.
The mirrors never fold in, but the puddle lights work.

I don't have the SDD (not sure what that stands for, but I'm sure it's the Jag diagnostic tool) to go through and see what the car is reporting.

Battery is brand new, and terminals were cleaned.

 

Update. I just got back from the dealer. They said the system had no codes to report and after a while of updating various software, still no locking. They told me they'd have to start looking in the wiring loom. I wasn't prepared to leave the car so I had them button it up and I went on my way.

Now I have no idea what it could be. Probably a short to ground somewhere or maybe something not connected correctly. I really have no idea. The only door I didn't get into was the driver's rear.

 

Well the error codes include short to ground an open circuit errors so I am not sure what the dealer is saying? If you unplug a module or a door lock the system can detect that and will set a code?

SDD = Symptom Driven Diagnosis which has now been replaced by Pathfinder for cars somewhere in the 2017-2018 range and up. This is the only software the dealers use.
Hope you can find it and post back as this one is a puzzle for sure.

They were probably saying that they want more money. LOL. I have no idea what the issue could be so for now I guess I just have to live with it.

 

Old thread...but my doors FINALLY lock. It was the KVM. Once that was replaced and programmed, everything works as it should.

 

Good to hear! Wonderful you came back and closed the thread with a working answer!

I had the dr lock symptoms on F type. The red warning triangle was on. I turned ignition off/on and saw the hood open warning. Fixed by opening/shutting hood and made sure it latched on both sides.

 

I wonder how vfrman found the problem with the KVM?
Must of set a code?

I took it to a shop and they figured it out. Not a cheap solution...
