Hello and welcome to Just, Super mechanic here. About your vehicle.

Here are the instructions for the ignition lock cylinder, thanks

Remove the steering wheel.

  • Remove the turn signal switch. It is not necessary to completely remove the switch from the column. Pull the switch rearward far enough to slip it over the end of the shaft, but do not pull the harness out of the column.
  • Turn the lock to Run.
  • If necessary, remove the ignition key.
  • If equipped, remove the buzzer switch assembly.
  • Remove the lock retaining screw and remove the lock cylinder.
  • To install:
    1. Rotate the key to the stop while holding onto the cylinder.
    2. Push the lock all the way in.
    3. Install the screw. Tighten the screw to 40 inch lbs. (5 Nm) for regular columns, 22 inch lbs. (2.5 Nm) for tilt columns.
    4. Install the turn signal switch and the steering wheel.
