Buick Regal Ignition Switch Guide: 1973-1988 Models
Is your classic Regal failing to start or stalling unexpectedly? The ignition switch could be the problem.
- A failing ignition switch can cause your Regal to stall while driving, which is a critical safety issue.
- Symptoms are almost always electrical (no-start, flickering lights, stalling), not mechanical (key hard to turn).
- No recalls exist for this part on 1973-1988 models; failure is due to normal age and wear.
- Brands like Standard Ignition are considered a top-quality replacement for long-term reliability.
Is Your Regal's Ignition Switch Failing?
After decades of use, the mechanical and electrical parts inside the ignition switch on a 1973-1988 Buick Regal can wear out. The internal contacts can become corroded or lose their spring tension, leading to poor electrical connections. This can cause a range of frustrating and potentially dangerous problems. Because failure can be sudden, it's important to recognize the warning signs before you get stranded.
Common Symptoms of a Bad Ignition Switch
- Engine Stalls While Driving: This is a critical symptom. Hitting a bump or even just vibrations from the road can cause a worn switch to momentarily lose connection, shutting off the engine. This also results in a sudden loss of power steering, making the car difficult to control.
- Car Won't Start or Starts Intermittently: You turn the key and nothing happens—no crank, no click. Or, it may start sometimes and not others. This is often the most common sign of a failing switch with worn internal contacts.
- Accessories Don't Work Correctly: The radio, wipers, or dashboard lights may not turn on, or they might flicker on and off as you drive. This happens when the contacts for the 'Accessory' or 'Run' positions inside the switch are failing.
- No Power When Key is Turned to 'On': If you turn the key to the 'On' position before starting and the dashboard warning lights do not illuminate, the switch is likely failing to send power to the main electrical systems.
Choosing the Right Aftermarket Ignition Switch
For a classic vehicle like the 1973-1988 Regal, new OEM parts from Buick are generally no longer available. The market consists of aftermarket brands that can be grouped into different quality tiers.
| Brand Tier | Available Brands | Quality & Price Assessment |
|---|---|---|
| Premium Aftermarket | Standard Ignition (SMP) | Standard is a highly respected brand known for producing parts that meet or exceed original specifications. Reviews consistently point to good fitment, high-quality materials, and long-term reliability, making it a top choice for owners who want a fit-and-forget solution. |
| Quality Aftermarket | Rostra Powertrain | Rostra is a well-regarded manufacturer of automotive electronics with quality certifications and a reputation for reliable components. While less common than Standard for ignition parts, their products are a solid choice and often provide a good balance of quality and value. |
| Value / Budget | Replacement | This category includes various generic or store-brand parts. They are the most affordable option and can get your car running again. However, quality can be inconsistent, and they may not have the same durability as premium brands. They are a viable option for budget-conscious repairs. |
Known Issues, Recalls, and Bulletins
Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or major technical service bulletins (TSBs) for the ignition switch on the 1973-1988 Buick Regal. The widely publicized GM ignition switch recalls of the 2010s involved much newer vehicles (like the 2004-2005 Regal) with a completely different ignition system design and do not apply to this generation. Failures on these older models are due to normal age and wear, not a specific manufacturing defect.
Frequently Asked Questions (FAQ)
Do I need special tools to replace the ignition switch?
No, you do not need special tools like a steering wheel puller for the ignition switch itself. The job requires basic hand tools like a socket set and screwdrivers. Special tools are only needed if you are replacing the ignition lock cylinder where the key goes.

For a DIYer with some experience, the job typically takes 1 to 2 hours. The main challenge is working in the tight space underneath the dashboard. 🎬 Watch this step-by-step ignition switch replacement on a 1979 Regal. A professional mechanic can usually complete the job in about an hour.
Will my original keys still work?
Yes. Since you are only replacing the electronic switch and not the mechanical lock cylinder, your original keys will continue to work perfectly.
Is it dangerous to drive with a bad ignition switch?
Yes, it is very dangerous. The greatest risk is the engine stalling while you are driving, which causes an immediate loss of power steering and power brakes, making the vehicle extremely difficult to control. It should be replaced as soon as symptoms appear.
