Depends on the year, if it is a newer truck than the theft system will have to be relearned. turn the key on and let it sit for 10 minutes. on some vehicles this works, otherwise you need to have it done at a gm dealer.

Did you activate the anti-theft system when you changed the ignition switch? If it has been activated you will need to have it reprogrammed at the dealer. good luck!

You don't. The ignition is required to start the car. If it fails you need a new ignition switch.

how can you start a '89 mercury cougar with a broken ignition switch?

it should be defective ignition switch................... It could be anything between the ignition switch and the terminal on the starter solenoid. There may be a bad ignition switch, bad ignition fuse or a bad fuseable link.

The ignition switch is where you insert your key to start car
