Over time, the key and ignition components in a 1999 Pontiac Grand Am will wear out, causing the key to not turn properly while in the ignition. Ultimately, this will keep the car from starting. Replacing the ignition can remedy the problem and can be done with basic hand tools in under an hour. Removing the ignition switch is the starting point for fixing any key or ignition problem.
Disconnect the negative battery cable from the battery terminal with the appropriate sized socket and ratchet.
Remove the trim piece surrounding the steering column. Unscrew the three Torx screws on the bottom of the piece and unhook the lower piece of trim from the upper piece. These are hooked together at the rear of the steering column, closest to the instrument cluster.
Unscrew the two screws on the top of the trim piece surrounding the instrument cluster and pull it forward to remove it.
Remove the instrument cluster by unscrewing the six screws securing the cluster, two on the top, two on the sides and two on the bottom. Pull the cluster forward, remove the electrical connections and completely remove the cluster.
Pry out the small trim piece around the ignition by placing a small, flat head screwdriver behind the piece and applying pressure.
Insert a small screwdriver behind the radio trim piece and pry it forward, repeating at different points around the piece until it comes off.
Remove the four screws securing the radio in place, disconnect the antenna and stereo connections then pull the radio completely out.
Unscrew the two bolts holding the ignition in place with the appropriate sized socket and ratchet.
Disconnect the electrical connectors from the ignition.
Depress the small tab in the middle of the ignition to disconnect the interlock cable.
