The ignition switch on a Pontiac Sunfire signals the ignition system to begin the engine starting process. If the ignition switch fails, then the key will no longer work and the car won't be able to start. To fix this problem, the switch must first be removed from the Sunfire. The job can be done in a few steps.

Tools Used[edit]

3/8-inch ratchet and socket set
Phillips head screwdriver

Remove the Ignition Switch[edit]

  • Pop the hood. Disconnect the negative terminal from the battery with the 3/8-inch ratchet and socket, then disconnect the positive terminal. Remove the steering column covers from the steering column using the Phillips head screwdriver.
  • Put the key in the ignition. Turn it to the "Run" position, but do not start the Sunfire. Locate the locking button located on the backside of the ignition cylinder housing. Push the button and then pull the lock cylinder away from the column.
  • Unscrew the ignition switch from the steering column using the Phillips head screwdriver. Unplug the wiring to the switch by hand, then take the switch up and off of the steering column and away from the Sunfire.
