my car got immobilelized (key won't work) , My son kept trying to start it with a key that was not programmed. I unhooked the battery because the elec. cooling fans would continue to run after I tried to start it and removed the keys. Charged a dead battery, the key that used to work, don't work anymore. immobilation lite on dash showing. Can I reset anyway or bypass the signal.

Since you have immo3, you can't immediately reset it. If the battery is too low the immobilizer will be activated. Leave the car on for a half hour with a charger and see if it is fixes itself. It should. If it doesn't, sometimes it goes away overnight. It should have gone away immediately. You need the tools mentioned in the resources section to work with the immobilizer system.
