ok i have searched. and changed batteries.

the sigma m? fob flashes good 3 times, but i thought it only pulsed for a second.

the imob wont activate, i have tryed to do it via the keypad but the led on the keypad wont flash at all when i put the pin numbers in. is it the fob or the unit..
i have searched and some have similar probs but not the same..
i have tryed it with door open/closed, ignition on/off and any variation of those..

i cant find my spare fob..

many thanx for your time ...lazza...

 

If the LED built into the keypad doesnt flash at all when you press a digit this would suggest that the keypad has no power supply or earth. As these are supplied through the alarm ECU it could be that you have a poor power supply or earth to the alarm ECU - hence no response from your Radio Key.
I would check your fuses and connections to the alarm...
