A Note on Buick Model Years
Before you shop for parts, it's important to know that the Buick Regal was not produced for the North American market for the model years 2005 through 2010. Production of the fourth-generation Regal ended in 2004, and the fifth generation did not begin until 2011. If you own a mid-size Buick sedan from the 2006-2010 period, you most likely have a Buick LaCrosse, which was produced from 2005-2009. This guide will focus on the ignition switch for the 2005-2009 Buick LaCrosse, as it is the correct vehicle for this timeframe.
The GM Ignition Switch Recall
The 2005-2009 Buick LaCrosse was part of a massive and serious General Motors recall for faulty ignition switches. The defect could cause the switch to move out of the 'run' position if the key was bumped or had a heavy keychain. This would shut off the engine while driving, 🎬 Watch: 8 common symptoms of a failing ignition switch disabling the power steering, power brakes, and, most critically, the airbags. Before buying any parts, check your Vehicle Identification Number (VIN) on the NHTSA website to see if the recall work was performed on your car. If it hasn't been, a GM dealer must perform the repair for free.
Choosing the Right Aftermarket Ignition Switch
If your vehicle's recall has been completed and the switch has failed again, or if you are replacing the lock cylinder and want to replace the switch at the same time, you have several options. The ignition switch is a critical safety component, so quality matters more than price.
- Tier 1: OEM / OE-Equivalent Brands. AC Delco is the original equipment manufacturer for GM. Choosing an AC Delco part, even from a local parts store, ensures you are getting the same quality and specification as the part your car came with. This is the safest choice for a critical component like an ignition switch.
- Tier 2: Reputable Aftermarket Brands. Brands like Standard Motor Products (SMP) have a long history of producing reliable aftermarket components. They are often a good balance of quality and cost. For a vehicle like the LaCrosse, an SMP switch is a solid choice if an AC Delco part is not available.
- Tier 3: Economy Brands. Store brands like Duralast or other budget-focused online brands offer the lowest price. While tempting, the risk of premature failure is higher. Given the history of ignition switch problems in these cars, saving a few dollars on a low-tier part is not recommended.
Estimated Replacement Cost (2005-2009 Buick LaCrosse)
| Part/Service | Estimated Cost |
|---|---|
| New OEM (AC Delco) Part | $45 - $70 |
| New Aftermarket Part | $20 - $50 |
| Shop Labor | $100 - $180 |
| Total Professional Replacement | $120 - $250 |
Pro Tip: While replacing the ignition switch, inspect the ignition lock cylinder—the part you put your key into. If the key feels loose, is difficult to insert, or doesn't turn smoothly, consider replacing both parts at the same time to save on future labor costs.
