The ignition assembly in your Buick is made up of the ignition switch and the lock cylinder. The lock cylinder is where you insert your key to start the engine. The ignition switch sends a charge from the battery to the starter in order to start the engine. You can find both of these components within the steering column. Replacing them is a job that will take over an hour to complete.

  1. 1

    Open up the bonnet of your Buick. Loosen the bolt on the negative battery terminal clamp. Pull the negative cable away from the terminal.

  2. 2

    Sit in the driver's seat of your Buick. Unclip the connectors around the steering wheel that hold the steering wheel cover in place. Pull the cover off the steering wheel.

  3. 3

    Lift the horn and air bag out of the steering wheel. Use your hands to pull out the electrical connectors that fix them to the centre of the wheel. Place them in a safe area. Use a Phillips screwdriver to remove the screws that hold the upper steering column cover in place. Lift the cover away from the column to again access to the ignition assembly.

  4. 4

    Remove the electrical wiring attached to the ignition switch by pulling it out with your hands. Place your key in the ignition and turn it to the on position. This will reveal the lock cylinder retaining pin. Use a small screwdriver to unhook the locking pin and remove the lock cylinder and ignition switch from the Buick.

  5. 5

    Press the new ignition switch into the locking tabs on the new lock cylinder so that they lock together. Place the components back into the steering column. Reattach the retaining pin to the lock cylinder to secure it in place. Fix the electrical wiring back into the ignition switch using your hands. Reattach the steering column and steering wheel components by following the removal steps in reverse.

  6. 6

    Reconnect the negative cable to the battery terminal. Turn on the engine of your Buick to check that the new ignition switch and lock cylinder work correctly.
