Just read it all again and from it I see this.
The remote has never worked? Is the RF receiver unplugged?
The central locking doesnt work with key in door manually.
The EKA is not accepted.
So a question does the key work in the glove box? The reason for the question is if somebody has changed lockset with secondhand this is very rarely done (it seems).
The key in the door does not work the central locking, so micro switch or wiring issue?
The EKA wont work if there is a problem with the lock switches/wiring.
The car wont accept fob commands? has it ever? (doesn't sound like it). This was covered in a post earlier as with Nanocom should be able to see a valid fob code received.
If the lockset/keys/fobs were changed but not the BECM the fob will not be seen as valid. If the BECM was changed then it should see the fob to sync that way. is it possible with both messages showing? not sure as i have never had both, only engine disabled and always synced with fob.
If the BECM was changed then the factory EKA from LR wont work. With door latch switches not working the EKA wont work. If the garage entered the supplied EKA (no reason to think they cant do that) and it didnt work it leans towards the BECM being changed. But why wont the fob work?
So I know none of this helps and has been said within the posts here already, I was perhaps looking for something that would pop out by putting all my thoughts down
but sadly no, Maybe it may jog somebody elses grey cell
. But the OP really has 2 choices the way I see it as nobody in his area can fix it. It seems that many garages/specialist's in europe don't have the proper equip/knowledge of these cars.
Did
@julien2512 ever actually speak with
@mozz smith ? cos if mozz has talked to him surely he would have got to the bottom of the real issue and how to fix.
1. Send the whole lot to Rick. Only the OP will know how easy it will be as regards import/export for repair.
2. Get it back home and start to check switches and fix them. for when the BECM comes back from Rick.
3. Cry
