For the ignition switch on 2009 and earlier models, disconnect the cable from the negative terminal of the battery, remove the steering column covers, disconnect the electrical connection, release the two locking tabs, and pull the switch away from the steering column, with installation being the reverse of removal. For 2010 and later models, remove the center console trim panel, take out the ignition switch housing bolts, pull the housing out of the dash, disconnect the electrical connector, depress the tabs on the sides of the switch to remove it from the housing, and reinstall in reverse order. If changing keys or the tumbler, reprogramming is necessary for the vehicle to start. Ensure the switch snaps into place during installation. The push button start system operates using electronic modules instead of a lock cylinder and key, with the Remote Function Actuator utilizing battery voltage to mimic the function of a conventional key. The start/stop button sends a momentary signal to the module, which checks various inputs before authorizing the car to start using the wireless Intelligent Access key fob signal. Testing and repairs for this system are typically beyond the capabilities of a home garage, so professional assistance is recommended.

Disconnect the cable from the negative terminal of the battery. Remove the instrument cluster upper and lower trim panels.

The ignition switch is located below the steering column behind the knee bolster and must be removed for checking. Using an ohmmeter or self-powered test light along with the provided diagrams, check for continuity between the indicated switch terminals in each of the specified positions. If continuity is not as required, the switch should be replaced. To replace the switch, first disconnect the negative battery cable followed by the positive battery cable and wait two minutes. Turn the ignition key lock cylinder to the Run position, then remove the center trim panel for 2002 and earlier models along with the driver side knee bolster. Unplug the ignition switch electrical connector and remove the retaining screws; on some later models, a tab retains the switch, which must be depressed to remove it. Disengage the ignition switch from the actuator pin and take it out of the vehicle. Ensure the actuator pin slot in the new ignition switch is in the Run position, as a new replacement switch will be set in this position. Position the new switch on the actuator pin and install the retaining screws, adjusting the switch as necessary to align the screw holes. Finally, the installation process is the reverse of removal, and proper operation of the ignition switch should be checked in the lock, start, and accessory positions.
