Central locking problems - keyfob won't lock/unlock - no CA
 

Hi guys,

I ran into an issue with my X today. In the morning I locked/unlocked it just fine, then 30 minutes later it would not lock/unlock with both key fobs. I was able to manually unlock the car and it started just fine. The central locking was working from the dash button too. Still, both key fobs were dead. Even the trunk would not open with the remote button.
Not sure why but I decided to open the trunk and close it and then magically both key fobs started working again. I checked for error codes but none were recorded.
Any ideas what might have caused the issue?
