It always used to flash slow, had trouble with the door handle not working yesterday and since then the little led is fishing really fast...all doors are closed so its not that, any ideas..can I just ignore it?

The LED flashes quickly if a door or tailgate in not locked correctly.

You say door handle, inside or outside? Just out of curiosity, I had my inside release fail on 3 door passenger door, fixed it myself but not go round to a guide yet.
