Parts
- Ignition lock cylinder assembly × 1 — Use OEM specification
- Ignition lock cylinder retainer clip (if damaged) × 1 — Use OEM specification
Preparation
- Park vehicle on level surface and engage parking brake
- Shift transmission to PARK position
- Disconnect negative battery cable and wait 2 minutes for airbag system to discharge
- Tilt and telescope steering wheel to lowest and fully extended position for maximum access
- Turn ignition to RUN position (DO NOT START - battery already disconnected for reference)
- Adjust driver's seat fully rearward for working room
Procedure
- 1Remove lower steering column coversRemove the two T20 Torx screws from the bottom of the lower steering column cover. Carefully pull the lower cover away from the column, releasing the retaining clips. Set aside in a safe location.Torque specCover Screws14 Nm (10 lb-ft)
- 2Remove upper steering column coverRemove the two T20 Torx screws from the upper steering column cover. Gently separate the upper cover from the column, being careful not to damage the plastic clips. Note the orientation of the covers for reassembly.Torque specCover Screws14 Nm (10 lb-ft)
- 3Disconnect ignition lock cylinder electrical connectorLocate the electrical connector on the back of the ignition lock cylinder housing. Press the locking tab and carefully disconnect the wiring harness connector. Move the wiring aside to provide clear access to the cylinder.⚠Do not pull on wires directly - always use the connector body to avoid damaging terminals.
- 4Access lock cylinder retention pin holeUsing a flashlight, locate the lock cylinder retention pin access hole on the side of the ignition lock housing. This is a small circular hole approximately 3mm in diameter located near the front of the cylinder housing. Clean any debris from around the access hole.ℹ️The retention pin access hole is only visible with the cylinder in the RUN position - since battery is disconnected, verify cylinder position before removal.
- 5Release lock cylinder retention pinInsert the original key into the lock cylinder (battery disconnected, so this is for mechanical release only). While gently pulling outward on the key/cylinder, insert a small pick tool or awl into the retention pin access hole and depress the retention pin. The pin must be fully depressed to release the cylinder.⚠Apply only gentle outward pressure - forcing the cylinder can damage the housing or retention mechanism.
- 6Remove ignition lock cylinderWhile maintaining downward pressure on the retention pin with the pick tool, continue to turn the key to the RUN position and pull the lock cylinder straight out of the housing. Remove the cylinder assembly completely and set aside. Inspect the retention pin and housing bore for damage or wear.ℹ️If cylinder does not release smoothly, verify retention pin is fully depressed and key is in correct RUN position.
- 7Inspect lock cylinder housingExamine the lock cylinder housing bore for any debris, damaged retention pin spring, or worn retention surfaces. Clean the bore with a lint-free cloth if needed. Verify the retention pin spring returns properly when released. Check that the wiring connector is clean and undamaged.⚠Do not spray lubricants into the lock cylinder housing as this can attract dirt and cause binding.
- 8Prepare new lock cylinderInsert the new key into the new lock cylinder and turn to the RUN position. Verify the key turns smoothly through all positions (LOCK, ACC, RUN, START). The cylinder MUST be in the RUN position with the key inserted for installation. Verify the retention pin is visible and spring-loaded.⚠Installing the cylinder in any position other than RUN will prevent proper installation and may damage components.
- 9Install new lock cylinderWith the new cylinder in RUN position and key inserted, align the cylinder with the housing bore. Carefully slide the cylinder straight into the housing until the retention pin engages with an audible click. Gently pull outward on the key to verify the retention pin has fully engaged and locked the cylinder in place.ℹ️The cylinder should slide in smoothly without force - resistance indicates misalignment or incorrect key position.
- 10Test lock cylinder operationTurn the key through all positions (LOCK, ACC, RUN, START) multiple times to verify smooth operation and proper retention in each position. The key should turn freely without binding. Attempt to remove the key in the LOCK position only to verify the interlock system is functioning properly.
- 11Reconnect electrical connectorAlign the ignition lock cylinder electrical connector and press firmly until the locking tab clicks into place. Gently tug on the connector to verify it is fully seated and locked. Ensure no wires are pinched or under tension.
- 12Reinstall steering column coversPosition the upper steering column cover over the column, aligning all mounting points and ensuring wiring is properly routed. Install the two T20 Torx screws and torque to specification. Install the lower cover, engaging all retaining clips, then install the two screws and torque to specification.Torque specCover Screws14 Nm (10 lb-ft)
- 13Reconnect battery and initialize systemsReconnect the negative battery cable and tighten securely. Turn the ignition key to RUN position (do not start) and verify all dash warning lights illuminate normally. Check that the ignition security indicator behaves normally according to the owner's manual.
Reassembly
- Verify all steering column cover screws are torqued to 14.0 Nm (10.0 lb-ft)
- Confirm no tools or parts remain in the steering column area
- Return steering wheel to normal driving position and verify full adjustment range
- Return driver's seat to normal position
Verification
- Start the engine to verify ignition system functions properly and engine cranks normally
- Turn ignition OFF and verify key can be removed only in PARK position
- Cycle the key through all positions (LOCK, ACC, RUN, START) five times to confirm smooth operation
- Verify steering wheel locks when key is removed and in LOCK position
- Check that all electrical accessories (radio, power windows, lights) function normally in ACC and RUN positions
- Confirm no warning lights related to anti-theft or ignition system remain illuminated
- Test that transmission will not shift out of PARK unless brake pedal is depressed and key is in RUN
- Verify steering column covers are secure with no rattles or loose fasteners
