as title suggests ^^
Firstly my remote central locking packed up. Battery in fob is fine, I even had the terminals resoldered not long ago, so I know there's nothing simple gone wrong within the key itself. There's no LED flash/light up when you push the button on the key, and the central locking doesn't work off the remote, however works fine using key in drivers door.
secondly (and it could be related) the hazards always used to flash when you locked/unlocked the car, but now they don't... they work as hazard lights and as indicators, but just not when locking/unlocking the car
