2009 Mk6 Remote locking inop

[PhilMc79]

So with all the mixed up weather we’ve been having I ran into a bit of trouble with my remote key. Came out of the house unlocked the car, took something out and locked it. 2 minutes later went back out and key remote stopped working!! Tried batteries etc but still won’t lock or unlock with the key... the key lights up when pressed but nothing happens.

any ideas would be greatly appreciated
