2002-2007 Saturn Vue Ignition Lock Cylinder & Switch Assembly replacement/ reinstallation

Replacing the Ignition Lock Cylinder & Switch Assembly (with Keys) in a 2002-2007 Saturn Vue

Part 1: Removal of the Old Ignition Lock Cylinder & Switch

1. Disconnect the Battery – Remove the negative terminal to prevent electrical shorts or airbag deployment.

2. Remove the Steering Column Covers – Use a trim tool to release the clips on the upper and lower steering column shrouds and take them off.

3. Locate the Ignition Switch Bolts – Under the column, you’ll see three 10mm bolts securing the ignition switch to the steering column.

4. Remove the Bolts – Use a 10mm socket (a swivel extension helps) to unbolt and set them aside.

5. Unplug the Electrical Connector – Disconnect the wiring harness from the ignition switch.

6. Release the Lock Cylinder – Insert the original key, turn it to "ACC" (Accessory), then press the release pin (small hole near the cylinder) while pulling the cylinder straight out.

Part 2: Installation of the New Ignition Lock Cylinder & Switch

1. Insert the New Lock Cylinder – With the key in "ACC", slide the new cylinder in until it clicks.

2. Reinstall the Ignition Switch – Align the switch with the column, then secure it with the three 10mm bolts. Tighten snugly but avoid over-torquing.

3. Reconnect the Wiring – Plug the electrical connector back into the switch.

4. Test the New Assembly – Reconnect the battery and verify the key turns smoothly through all positions (OFF, ACC, ON, START).

5. Reattach Steering Column Covers – Snap the upper and lower shrouds back into place.
