Pontiac Aztek Ignition Switch Replacement Cost

When ignition switch issues arise, it will be dangerous or impossible to drive the car. Depending on the point of failure, the vehicle could leave you stranded, stall in traffic, or even fail to turn off the engine when the key is removed. You should have the ignition switch repaired as soon as possible.

Most cars and trucks won't have issues with the ignition switch, but if they occur, they typically happen to older, high-mileage vehicles.

Because ignition switch problems are rare, a mechanic will typically check several other components before assuming it's the culprit. First, fuses and relays will be looked at. Then the starting and charging system may be checked, depending on the symptoms. If the other components of the starting and charging system are functioning properly, the ignition switch will likely be suspected. To check the switch, the technician will test voltages as the switch is moved to various positions. If it's not working as it should be, the switch will be replaced.

If the ignition switch and ignition lock cylinder are one component, replacing the switch will be very difficult if lock cylinder fails. If the lock cylinder works properly, the ignition switch is generally not too hard to remove. In most cases, the steering column plastic covers will be removed, and the lock cylinder will be turned and released. The ignition switch can then be taken out, after removing any obstructing or retaining hardware. Once the ignition switch is removed, a final bench test may be conducted to make sure it's the problem. The new switch will be installed and the lock cylinder will be put back in place. 

Replacing the ignition switch does not normally require replacement of the ignition switch lock cylinder, so the same key is normally used. If the lock cylinder is replaced, the ignition key will change as well.
