Got a Sigma alarm/immobilser fitted to my E34, everything works fine (for now) but I only have 1 fob which is on it's last legs (long one with 2 3V flat batteries)
After doing a fair bit of searching I'm pretty sure it's an SG30 - 1996 car and has a small keypad on windscreen without a * or #
I don't have ANY documentation for the alarm so don't have a pin
Anyone know where I can get a replacement fob or companies who can reprogram it?
I know I can't reprogram the fob myself so need a specialist - is this the route to go down or get the local Indy to remove it?
Any help would be great
