I've had a minor problem with the nearside passenger door lock for a couple of months. The door would not open from the outside but worked on the inner door handle. Now, it will not open at all. There is full movement on both inner and outer door opening handles but the door remains locked. It looks like a fault in the door lock but as the door is firmly shut, I cannot get to the lock to replace it.

Does anybody have a sure-fire fix for opening a locked rear passenger door?

Could this problem be a software problem - battery was changed some months ago but this door is not used much so it could stem from that - or is it likely to be the failure of one of those dreaded little motors in the lock mechanism?
Has anybody actual replaced those motors or is it simpler to buy a new lock complete - they're on Ebay for about £30?

Thanks for any help.

Same problem for me.....rear offside passenger door not opening from the outside......
If I were you, I'd tackle the job now before the inside opening handle packs up too. There's plenty of youtube videos of how to do it - my problem now is I cannot open the door from the inside or outside to change the lock. See here

Thanks for the video.
Good point.
Just need to work out the part number.........
Any luck with getting yours open? Was it starting to fail for a while before getting stuck?

I had this happen to me a few months back on my X260
I can't comment on what fixed it as it went back to Jaguar, but it seems to be a common issue on the XF.

You may be able to remove the door card from the inside, but that means getting the lower back seat out.
There are four sockets which hold it down, the sockets have little handles that release the seat base, if you lift the curved edge of the seat base on the drivers side, you'll be able to see and feel for it. One on each curve and one either side of the transmission tunnel.
The seat base then lifts up and pulls away from the backrest. The seatbelt buckles remain.

You'll probably need a set of plastic trim tools to get the door card off, so you don't damage the card.

Short of that, a Dealer vist might be required.

Thanks for that.

I had thought that it is possible to remove the door card from the inside but you cannot remove the lock with the door closed - there is a screw that connects to the external door handle which is only accessible from the rear edge of the door with the door open. I'm stumped unless there is a way, with the door card removed but the door closed, to overcome the internal workings of the lock mechanism so that the door will open.

Any thoughts, anybody?

Surely there must be some way to mechanically open the door once you get the card off?

Just out of curiosity, have you checked the fuses to make sure power is getting to the door?

Removing the door card won't help as you can't get the door lock mech out with the door closed Steve.. there are three bolts/screws around the clasp/claw itself which are on the 'end face' of the door furthest away from the hinge which is hidden when the door is closed, there are close to the 'child lock' determinator....

Hi Jordan, I'd suggest getting this sorted sooner rather than later if I were you.. I was lucky and the door still opened meaning that I could fix it... (y)

But Pete, unless the latch is fully electronic and therefore fly by wire, surely if you can get to the inside of the door, you can poke a screwdriver or something in and unlatch it?

If it's fly by wire, then maybe an SDD session to reload the software into the door lock module might do the trick?
How the heck else are you able to open the door then?

Seems it is fly by wire to an extent. An Electro-mechanical lock.
This 'replacing' video explains it fairly well.


Problem is opening the door without damaging it. :(

mmm.. the XF lock mech isn't fly by wire Steve so should still open from the inside.. but in CVB's case it won't.. (Broken cable?..)

Having just changed my rear left door lock mech (which is a complete bitch of a job the first time) I would be extremely doubtful you could do anything with the mech still in situ due to it's all but 'wedged in' position.

I for one don't have the quadruple jointed forearms, patience or resolve for such an attempt, changing a 'willing' passive lock mech was bad enough... :D

Think you've gone mad Pete... Pretty sure its Tom
You might be right Doc. Jordan.. but in my defence, I knew this would be my downfall one day:

You're talking yourself in circles here Pete... :)

So, it uses the cable (well two, one inside, one outside) to pull a lever which operates a motor which opens the door. Let's call it 'fly by lever' then ;)

In this case both cables probably haven't failed, so we assume the cable pull is working, therefore the motor has failed

The latch is still a mechanical device, so there must be some way to get at it from the inside and open it.
I fully agree that you'd need small hands and a decent pair of gloves to avoid hurting yourself, but it must be possible to get it to open?

Another thing to try is to see if the electric plug to the latch motor is still in place, it may have come off. Again this requires door card removal.

I'm pretty sure that the problem is inside the lock. It first showed itself by not opening from the outside and after a few weeks the inside handle stopped working as well so now I cannot open the (rear passenger) door at all. Have you found a good independent garage in Kernow to repair your car - I'm near Torpoint. I guess the first thing to do is get an electronic diagnosis to confirm it's the lock that's gone wrong, then I can order the part and tackle opening the door (door card off from the inside and fiddle with anything I can reach). I know that I cannot change the lock without opening the door.

Maybe the child lock is on so won't open from inside?

Geoff - that might explain why it won't open from the inside but not why it will not open from the outside. The index in the Owners' Manual is pretty rubbish but I eventually found out about the Child Safety Lock on page 25. I checked on my car and the offside door is not child locked and I've no reason to believe the nearside is locked, especially as it was working until a few days ago. I can't check for sure without opening the door!

I've spoken to my local garage (not a Jaguar specialist) and he said he'd had the same problem with a VW Passat. He fixed it by removing the door card from the inside then, basically smashed the lock to open the door , then fitted a new lock.

Looks like a last resort to me!
