A: I'm happy to help, Brian! Disconnect the vehicle's negative battery cable, it is usually clamped into place, so you must loosen the clamp nut with a wrench. Detach the trim covers on the steering column by removing the screws on the lower cover with a screwdriver. Remove the driver's side knee bolster by removing its screws. Insert the ignition key into the lock cylinder and turn it to the "Run" or "Start" position. Push a small Phillips head screwdriver or similar tool into the retaining hole at the top of the lock cylinder housing. Pull the ignition key and lock cylinder out of the housing together. Install the replacement cylinder with its key inserted into the housing, making sure its retainer aligns with the retainer slot in the housing; the cylinder needs to be installed in the "Start/Run" position. Push in the cylinder so the retainer snaps into position. Turn the cylinder into the "Lock" position and remove the key. Reconnect the trim covers and the negative battery cable.
I have an 2001 Alero that the key keeps sticking and won’t turn. I am thinking of changing the ignition key lock cylinder to see if that helps. When it does turn the car starts with no problem. My question is would it be acceptable to use a used cylinder from a junk yard? Seems much cheaper than the $150 that the autoparts want.
