Warnings

Tools required

Parts

• Ignition lock cylinder × 1 — Use OEM specification
• Ignition lock cylinder retaining clip (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery cable and wait 2 minutes for airbag system discharge
3. Adjust steering wheel to lowest position for maximum access to column covers
4. Ensure you have the original ignition key available

Procedure

1. 1

   Remove lower steering column cover
   Locate the fasteners securing the lower steering column cover. Remove the Torx fasteners from the lower cover (typically T20). Carefully pull the lower cover away from the column, noting any clips along the edges that may require gentle prying with a flat-blade screwdriver.
2. 2

   Remove upper steering column cover
   Remove the Torx fasteners securing the upper steering column cover (typically T20). Separate the upper cover from the lower cover area and lift it away from the steering column. Set both covers aside in a clean area.
3. 3

   Disconnect ignition switch electrical connector
   Locate the ignition switch electrical connector on the steering column. Press the release tab and pull the connector straight out from the ignition switch. Move the wiring harness aside to prevent interference during lock cylinder removal.
4. 4

   Insert key and rotate to RUN position
   Insert the ignition key into the lock cylinder. Rotate the key clockwise to the RUN position (second detent, just before START). The lock cylinder must be in this position to align the internal release mechanism for removal. Do not turn to START or ACC position.
5. 5

   Locate lock cylinder release access hole
   With the key in RUN position, locate the small access hole on the steering column lock cylinder housing. This hole is typically positioned on the underside or side of the cylinder housing near the key entry point. Use a flashlight to clearly identify the hole and the release pin or tab visible inside.
6. 6

   Depress lock cylinder release mechanism
   Insert a small punch, paper clip, or dedicated lock cylinder release tool into the access hole. Apply firm inward pressure to depress the internal release tab or pin. You should feel the tab compress approximately 1/8 inch. Maintain steady pressure on the release mechanism.
7. 7

   Remove lock cylinder from housing
   While maintaining pressure on the release mechanism, gently pull the ignition key and lock cylinder assembly straight out from the steering column housing. The cylinder should slide out smoothly with the key still inserted. If resistance is felt, verify the cylinder is still in RUN position and the release mechanism is fully depressed. Remove the key from the old cylinder once extracted.
8. 8

   Inspect lock cylinder housing and components
   Examine the steering column lock cylinder bore for any debris, damaged retaining clips, or worn components. Check the condition of the lock cylinder retaining mechanism inside the housing. Clean any dirt or debris from the housing bore using a lint-free cloth. Verify the retaining clip is present and undamaged.
9. 9

   Prepare new lock cylinder for installation
   Insert the ignition key into the new lock cylinder. Rotate the key to the RUN position (same position used for removal). Verify the key rotates smoothly through all positions and returns to LOCK properly. Inspect the new cylinder for the presence of the retaining groove or notch that engages the housing mechanism.
10. 10

    Install new lock cylinder
    With the key in RUN position in the new cylinder, align the cylinder with the steering column housing bore. Ensure the flat or keyed section of the cylinder shaft aligns with the corresponding slot in the housing. Slide the cylinder straight into the housing until you hear or feel a distinct click indicating the retaining mechanism has engaged. Gently tug on the cylinder to verify it is locked in place.
11. 11

    Test lock cylinder operation
    Rotate the key through all ignition positions: LOCK, ACC, RUN, and START. Verify smooth operation in each position and proper return to LOCK. Confirm the key can be removed only in the LOCK position. Check that the steering wheel lock engages when the key is removed and released when turned to ACC or RUN.
12. 12

    Reconnect ignition switch connector
    Align the ignition switch electrical connector with the switch terminal on the steering column. Push the connector firmly until the locking tab clicks into place. Verify the connection is secure by gently pulling on the connector body.
13. 13

    Reinstall steering column covers
    Position the upper steering column cover over the column, ensuring all edges are properly aligned and any locating tabs engage their corresponding slots. Install the Torx fasteners and tighten evenly. Position the lower steering column cover, engaging any clips along the edges. Install the lower cover Torx fasteners and tighten securely. Verify all cover edges are flush and properly seated.

Reassembly

1. Reconnect the negative battery cable
2. Verify all steering column covers are properly secured with no gaps or loose fasteners
3. Ensure no tools or parts were left in the steering column area

Verification

• With battery reconnected, insert key and verify ignition operates through all positions: LOCK, ACC, RUN, and START
• Confirm engine starts normally and steering wheel lock engages/disengages properly
• Verify all electrical accessories function normally (gauge cluster, radio, power windows)
• Check that the key can only be removed in LOCK position
• Verify no warning lights related to ignition system or security system illuminate on dash
• Confirm steering column covers are secure with no rattles or movement
