The Body Control Module or BC Unit controlls all aspects of the cars security and windows etc. The RF Reciever is in the boot and then sends the signal to that. There is a lot of info on the workshop manual on the subject, but here is the summary for the RF Reciever:

RF Receiver
The RF receiver converts the signals from the RF remote handset into digital messages and transmits them to the BCU. The RF receiver is integrated into the rear window antenna amplifier installed behind the inner trim on the top left edge of the upper tail door. Operation of the receiver is powered by a permanent battery feed from the rear fusebox. 

Thank you Dan
I asked that because I had project to change my horrible key to another one. I'll move the transponder from the LR key into the new keyfob. But with your answer, I'm not sure I would be able to connect the new module...
The button of my old key are in very bad condition... and I realy don't want to pay about 270 euros for a new one...

Can you not buy a key from ebay and swap the electronics? 2004 black Vogue TD6

Agreed, you should be able to swap the entire insides of your key for any replacement. Or just pay the £75 for one from a stealer. 

You are right, I can buy a new one, and move all electronics and transponder from mine to the new, but I wondering if I could use one those we can find on the web like this models :

Hi All,
Rather than start a new thread I thought I'd follow this one as it is related.
My Remote locking is intermittent at best.
I've tried swapping the battery in the key and re-syncing but it struggles to sync/work and I don't think it is the key as the little red LED on the key flashes fine.
I only have the one key (for now) so I think it is the receiver.

I have uploaded a couple of photo's to show the item and where it is located on a 2004 L322.
All you have to do is pull the top plastic panel off, it is held with plastic clips that stick into metal clips. You need to pull the panel off squarely (not at an angel).

Hi Folks.
Just to follow up, bought a new receiver off ebay, fitted it and sync'd the key straight away. It works a treat now. I took the old unit apart and found this. It looked fine from the outside too.

I probably have the same problem. Did you opt for "updated" part number or figure out if there is a difference?

I think I just bought like for like as that was the cheapest one on Ebay at the time. It worked perfectly and I have never had a problem since.

Try changing the battery in the key fob

Hi folks

I picked up a 2007 Vogue and neither of the key remotes work or re-sync, figured it could be the key so bought another and it also fails to resync but my little key rob rf tester is picking up good or strong signal from the key before I press the button.

I expect I need to replace the XUO500040 module, but I noted it has links to the rear window glass and an antenna off under the headlining. Does anybody know if the key receiver is the rear window aerial or up in the shark fin? I also have no GPS signal on the nav so I’m wondering if I should be looking at the aerial in the roof before I splash £150 on a new module!

Annoyingly, the car was unlocking on the key before I had the faulty steering column replaced and now the alarm goes off every time I unlock the car so my remote locking issue has now shot to the top of the repair list!

Cheers
