How do you replace ignition switch without key?

Replacing an ignition switch without a key typically requires bypassing the lock mechanism. You can access the ignition switch by removing the steering column cover, then disconnecting the wiring harness attached to the switch. If the switch is locked, you may need to drill out the lock cylinder or use a slim jim tool to release it. After removing the old switch, install the new one and reconnect the wiring before reassembling the column.
