Engine will not start

[dean]

Hi I went to start my beetle today, has not been started for a while, charged battery up and the immobiliser light seems to be staying on usually it flashes. When I turn the key the relay 30 makes a buzzing noises and the engine will not even turn over. Not sure what is going on, have not had a problem like this before. I have a spare relay and it hasn't made any difference, used a different key fob which also has not changed.Wonder if it could be the immobiliser? Would be grateful for any help.

Thanks in advance
