The remote central locking stopped working on my car a few days ago. Installed new batteries in both remotes (although didn't get Flat Battery message on the display) - no go. Tried to re-program the key as per handbook (following battery replacement) - still no go. Both central locking fuses are OK. Prior to that both remotes worked OK.
Any idea what the next step to diagnose the fault should be?

FIXED - disconnected the car battery for 5 minutes, the remote now working again.
