This procedure covers the removal and replacement of the ignition lock cylinder on a 2021-2024 Ford F-150 with 3.5L EcoBoost V6 engine, including steering column cover removal and ignition switch components.

Warnings

Tools required

Parts

• Ignition lock cylinder assembly × 1 — Use OEM Ford specification
• Steering column cover screws (if damaged) × 4 — Use OEM specification
• Ignition lock cylinder retaining pin × 1 — Usually included with new lock cylinder

Preparation

1. Park vehicle on level ground and set parking brake
2. Turn steering wheel to centered position
3. Disconnect negative battery terminal and wait minimum 2 minutes for airbag system discharge
4. Adjust steering column to lowest and fully extended position for best access
5. Remove any personal items from steering column area

Procedure

1. 1

   Remove Lower Steering Column Cover
   Locate the lower steering column cover below the steering wheel. Remove the T20 Torx screws securing the lower cover (typically 2-3 screws on bottom edge). Carefully pull the lower cover away from the column, releasing any retaining clips. Disconnect any electrical connectors for the hood release handle illumination if equipped.

2. 2

   Remove Upper Steering Column Cover
   With lower cover removed, locate the upper steering column cover screws (typically 2 T20 Torx screws at rear of cover near instrument cluster). Remove these screws and lift the upper cover upward and forward to clear the steering wheel and column. Set covers aside in safe location to prevent scratching.

3. 3

   Disconnect Ignition Switch Electrical Connector
   Locate the main ignition switch electrical connector on the right side of the steering column. Press the locking tab and disconnect the electrical connector from the ignition switch. If equipped with additional security connectors, disconnect those as well, noting their positions for reassembly.
   ⚠Do not force connectors - ensure locking tabs are fully released before pulling.
4. 4

   Insert Key to ACC Position
   Insert the current key into the ignition lock cylinder and rotate it to the ACC (accessory) position. This is required to release the lock cylinder retaining mechanism. The key must remain in this position for the next step.
   ℹ️If you cannot turn the cylinder with the existing key due to lock failure, you may need to drill out the retaining pin - consult a professional locksmith or dealer.
5. 5

   Release Lock Cylinder Retaining Pin
   With key in ACC position, locate the small access hole on the steering column housing near the lock cylinder (usually on underside or side). Insert a small flathead screwdriver or awl into the access hole to depress the retaining pin spring. You will feel resistance when contacting the pin.
   ⚠Use gentle pressure to avoid breaking the retaining pin mechanism inside the housing.
6. 6

   Remove Lock Cylinder
   While maintaining pressure on the retaining pin with the screwdriver, use your other hand to gently pull the ignition lock cylinder straight out of the steering column housing. The cylinder should slide out smoothly once the retaining pin is fully depressed. Remove the key from the old cylinder once extracted.
   ℹ️If cylinder does not slide out easily, verify key is still in ACC position and retaining pin is fully depressed.
7. 7

   Inspect Steering Column Housing
   With lock cylinder removed, inspect the steering column bore for any debris, damaged components, or worn retaining pin mechanism. Clean the bore with a lint-free cloth if needed. Verify the actuator rack inside the column moves freely and is not damaged.
   ⚠Do not allow debris to fall into the steering column housing as this may interfere with lock mechanism operation.
8. 8

   Prepare New Lock Cylinder
   Remove the new ignition lock cylinder from packaging and verify it includes the retaining pin (should be installed in cylinder or provided separately). Insert the new key into the cylinder and verify smooth operation through all positions (LOCK, ACC, ON, START). Ensure the cylinder is in ACC position for installation.
   ℹ️New lock cylinders typically come with the retaining pin pre-installed in the released position for ease of installation.
9. 9

   Install New Lock Cylinder
   With new key in ACC position, align the lock cylinder with the steering column housing bore. Ensure any alignment tabs or guides on the cylinder match the slots in the housing. Gently slide the cylinder into the housing until it seats completely. You should hear or feel a click when the retaining pin engages.
   ⚠Do not force the cylinder - if it does not slide in smoothly, verify alignment and key position.
10. 10

    Test Lock Cylinder Operation
    With cylinder installed, test operation by rotating the key through all positions: LOCK, ACC, ON, and START. Verify the key returns to ON position when released from START. Test that the key can be removed only in LOCK position. Verify the steering wheel lock engages when key is removed and steering wheel is turned slightly.
    ⚠If cylinder does not operate smoothly or key cannot be removed in LOCK position, remove and reinstall cylinder to ensure proper seating.
11. 11

    Reconnect Ignition Switch Connector
    Reconnect the main ignition switch electrical connector to the ignition switch on the steering column. Ensure the connector clicks into place and the locking tab is fully engaged. Reconnect any additional security connectors in their original positions.
12. 12

    Reinstall Upper Steering Column Cover
    Position the upper steering column cover over the column, ensuring it fits around the steering wheel base properly. Align the cover halves and install the T20 Torx screws at the rear of the cover. Tighten screws to specification, alternating between screws to ensure even seating.

    Cover Screws12 Nm (9 lb-ft)
13. 13

    Reinstall Lower Steering Column Cover
    Reconnect any electrical connectors for hood release illumination if equipped. Position the lower steering column cover and align all retaining clips. Press firmly to engage clips, then install the T20 Torx screws. Tighten screws to specification.

    Cover Screws12 Nm (9 lb-ft)
14. 14

    Reconnect Battery and Initialize System
    Reconnect the negative battery terminal. The vehicle may require initialization procedures. Turn the key to ON position (do not start) and allow all warning lights to complete their self-check cycle. Some models may require steering angle sensor calibration - turn steering wheel fully left, then fully right, then center.

Reassembly

1. Verify all steering column covers are properly secured with no gaps or misalignment
2. Ensure all electrical connectors are fully seated and locked
3. Check that all screws are tightened to specification and none were missed
4. Verify hood release handle operates properly if equipped with illumination

Verification

• Turn ignition key through all positions multiple times to verify smooth operation: LOCK, ACC, ON, START
• Verify key can only be removed in LOCK position
• Test that steering wheel lock engages when key is removed and steering wheel is turned
• Start the engine to verify ignition switch electrical operation is correct
• Check that all instrument cluster warning lights operate normally
• Verify no airbag warning lights remain illuminated after starting vehicle
• Test all ignition-controlled accessories (radio, power windows, etc.) in ACC and ON positions
• Ensure no rattles or loose components around steering column area
