2008 V50 remotes not working

Hi All,

I'm new to the site and after using search I know there has been quite a few remote control issue threads but I thought I would document mine in hope that it helps someone else in the future (thats if I do get it resolved). No indys worth their salt can dig into the problem before Christmas and im trying everything before bringing a tub of Vaseline to the main dealer.

So, timeline of the issue:
* Everything is working fine with my v50 that i have had for over a year and low and behold strangely one of the remote controls stops working, all buttons not just the lock and unlock
* I replace the battery and it its not that, still not working. Thats ok as I have another which is working
* So I get into work one morning last week and lock up the car as normal, go out to my car at lunch and the second remote has stopped working - balls.
* Car still opens with blade and starts with chip key, and central locking button on inside works which makes me think its not any central locking motors etc.
* I have had the remote fob tested with an auto spark who confirms the key is sending out the correct signal so must be an issue with the car receiving the signal
* I hook the car up to vida dice and nothing showing in fault - great
* I have checked all the relevant fuses and all seem to be fine, and I have tried replacing the RRX radio receiver module - again no joy.

Also dont know if relevant but you know the way the drivers door lock pops up/open when you take the key out after stopping the car, this doesn't work anymore either so I'm assuming they are related and hoping this will trigger something in someone's head.

All comments/opinions/suggestions welcome as I am at a loss and I hate getting beaten by cars lol

I don't think you could confirm your remote sent CORRECT signal. Signal include high frequency and low frequency (modulation). I believe your RF part is still works correct, but digital signal unfortunately crushed. Actually, this is common issue for 2008-2009 MY P1 cars. First generation of remote controls for this MY cars have a internal bug. In some years of using they are lost synchronization. For today I don't know solution for this case except programming new key.
