you need to first install one of factory key into ignition.turn ignition switch on position for 5 seconds.switch off the ignition and remove key.wait 7 seconds insert new key into ignition switch.and switch ignition on until alarm system warning lamp will flash twice mean key programmed. switch ignition off if warning light illuminate for 3 seconds to confirm or flash 3 times indicate registration has failed. if you fail on programming new key let dealership reprogram new keys using diagnostic equipment.

At you year make and model the factory alarm was just the pellet that disabled starter,the alarm was part of the ignition switch if anything you will need to replace the aftermarket alarm. A repair will cost you more than to replace the unit,You will have to cancel the aftermarket alarm under the dash and restore the ignition wire that is spliced for the alarm relay.

IT'S NOT LIKLEY THE IGNITION SWITCH, CHECK THE FUSES, THERE COULD BE MORE THAN A COUPLE ENVOLVED.

groan.....gunna need a bit more info. but i'll try. What portion of the ignition was ripped out? The tumbler + switch? If so, you might need to get the car's system resent to recognize that it has a new ignition put in. Sime vehicles have a theft prevention system in place to prevent the vehicle from running if its been hot wired. Your best bet would be to replace the damaged ignition components (You did not mention if you did or not). If it still doesn't work after you have replced all of the ignition components. You can try to reset the vehicle (doesn't work on all) disconnect negative battery terminal and go back into vehicle and press down the brake pedal for about 30 seconds then reconnect battery and try it....good luck, hope this helps
