Default Cobra alarm help think immobiliser is stuck

Hey all

My car has been sitting on the drive for about 6 months. Usually starts first time. But when I turn the key the dash lights come on. But the engine won't even turn over. No power to the electric windows. I reckon the immobiliser is stuck on. I think I can hear the fuel pump arm for a few seconds. Please help. Alarm was installed 5 years ago. Lost my pin. Still got both fobs ;(

Forgot to say I can arm and dis-arm the alarm using the fob. I've fully charged the battery in the car. Have set the alarm off to test it. All works ok.

It could be the immoby but worth trying a few other things first, such as check fuses etc.

The fact the ignition is on shows the immobiliser to be disarmed unless it's single point immobiliation. I.E cuts starter circuit in which case could be immobiliser fault, check you have power at the starter motor wire with the aid of an assistant, with ignition in starter position.

If above is ok it may just be the starter has jammed where it has been sat for a while either tap gently with a mallet or rock back and forth in top gear (Assuming manual).

If it is a full closure system and it is faulty this will stop the windows working as well.

Thanks for your help guys I'm still stuck. Although the key fob now will not disable the alarm or unlock the doors. It just makes a single beep. But the panic button works and also alows me to stop it. But doesn't disable it.

In going crazy here aarrgghh
