Disconnect the cable from the negative terminal of the battery. Remove the instrument cluster upper and lower trim panels. Using a small screwdriver, detach the tabs securing the Passive Anti-Theft System (PATS) transceiver to the ignition lock cylinder housing, then pull the transceiver off the housing and disconnect the electrical connector. Insert the ignition key into the ignition lock cylinder and turn it to the ACC position. Insert an awl or suitable tool into the hole in the underside of the ignition lock cylinder, then depress the ignition lock cylinder retaining tab and remove the ignition lock cylinder. To install the ignition lock cylinder, insert it into the lock cylinder housing and push it in until it clicks into place. Verify that the ignition switch operates correctly in the OFF, ACC, RUN, and START positions, with installation being the reverse of removal. For 2014 and earlier models, do not remove the ignition switch and the ignition lock cylinder at the same time to avoid damaging the steering column. Remove the fasteners securing the ignition lock cylinder housing, disconnect the electrical connector for the PATS transceiver, and disconnect the electrical connector from the ignition switch. Depress the release tabs to detach the ignition switch from the ignition lock cylinder, ensuring that it snaps into place during installation, which is otherwise the reverse of removal. For 2015 and later keyless entry models, carefully pry out the left-side center air register from the instrument panel using a trim tool, disconnect the electrical connector from the push start ignition switch, and from the back side of the instrument panel, depress the two retaining tabs on the switch then push the ignition switch button out of the instrument panel.
