Mk7 Indicators flashing when key is near van

[GarryH]

Hi, hopefully ye may be able to help. About a week ago the fob stopped working, along with this if I'm near the van with the key the indicators start flashing. I was just locking it from the drivers door first but now it unlocks pretty much straight away. I could do it 5 or 6 times before it would stay locked. I now have stopped locking it altogether because one day after locking it the only door that unlocked was the drivers. I haven't got as far as a garage to look at it yet and won't next week either with work commitments so I'd just like to know does anyone know what's going on with it
Thanks in advance
Garry
