  Q: How to replace the ignition lock cylinder on Buick Terraza?

  A: In order to replace the Ignition Lock Cylinder, disconnect the battery negative cable and disable the restraint system. Unscrew and pull off the Steering Wheel from the lower steering column trim covers, then fold the trim cover down and slide it backward to unlock the locking tabs, enabling the removal of the lower steering column trim covers. Next, unscrew the retaining screws on the upper steering column trim cover and lift it towards accessing the lock cylinder access hole. Tap the snap-on a173a bent-tip awl through the access hole of the Ignition Lock Cylinder and rotate the Ignition Lock Cylinder to start. Push down the retainer with the bent tip and allow the Ignition Lock Cylinder to the run position then withdraw it from the lock cylinder case. In install mode, have the Ignition Lock Cylinder pushed through the trim cover in the upper steering column with the lock cylinder retaining tab and position tab aligned with the slots in the lock housing. Then, push this entirely into the lock housing. Install the retaining screws to the upper steering trim cover and make sure that they are tightened down to 3.5 nm (31 inch lbs) to match the tab slots on the lower trim cover, match the tab slots on the lower trim cover with the locking tabs on the upper trim cover till tilts the lower trim cover up and slides it to make sure that the locking tabs snap into place. Add the lower trim cover screws to the steering column securing it on there with a force of 1.5 nm (13 in.
