Well everything has been working fine until now.... It has a SIGMA alarm fitted and I have 2 fobs.. I went to lock the car and nothing happened, but the key locks the car no problem.. So the small red light inside the car is not coming and I can't even start the car.. I have tried with both fobs and nothing, the lights on the fob come on when I press the button but nothing happens.. Any help would be great as this is the first time this has happened.... Please help
