how to uninstall an immobiliser?

I have my friends car for the week as i was changing some parts on it, it has a bulldog alarm and a moss immobiliser on it, i disconnected the battery, and now it won't start. I asked my friend about it and he said he doesn't use the alrm or the immobilser, he said if i'd be able to take it out.

Does anyone know how to unistall a immobiliser, so the car will start?

Thanks

Are you looking to remove the factory immoblizer or an after market bypass for remote start?

This would have nothing to do with the car not starting with the key. You should still be able to start the car with a key. But if you reset the alarm you might have to disarm the system in order to start the vehicle. If you dont have the keypad for the alarm use the vallet overide switch.
