Not a Mercedes problem this time but I could do with a bit of help!
My sons Fiesta has got an after market Sigma alarm fitted. Some times it is difficult to set / unset the alarm using the key fob. I am wondering if the battery in the fob is on its way out but I can't see any way of opening it to replace! He has a spare fob and this is exactly the same, sometimes it works first press, other times it takes several presses, could there be a fault elsewhere? Any help would be much appreciated.
This is the type of fob.
