To replace the ignition switch on a 1991 Buick Regal, first disconnect the negative battery cable to ensure safety. Remove the steering column cover by unscrewing the necessary screws, then locate the ignition switch, which is typically mounted on the steering column. Disconnect the wiring harness from the old switch, unbolt it, and then install the new ignition switch by reversing the removal process. Finally, reassemble the steering column cover and reconnect the battery.
