Help needed - dicsonnected battery now car is immobilised =(
 

Hi guys,

I have a 2000 MR lancer which I had to take the battery out to change a filter. I think it has an after market immobiliser and when I have diconnected the battery it has engaged this. My car now won't start and I have no idea what to do. Has anyone else had the same problem or any suggestions on how to fix it? =)

Tah muchly!
