Chevrolet Impala Ignition Switch Guide for 1987-1997 Models
Having trouble starting your 1994-1996 Impala SS? Your ignition switch might be the problem.
- A failing ignition switch can cause a no-start condition or, more dangerously, cause the engine to stall while driving.
- The major GM ignition switch recalls from the 2000s/2010s do NOT apply to the 1987-1997 Impala/Caprice platform.
- For reliability, choosing a well-regarded aftermarket brand like Standard Ignition is recommended over a generic 'Replacement' brand, as the labor to access the part is involved.
- Symptoms like flickering dash lights or accessories that don't work are also common signs of a failing ignition switch, not just a dead battery.
Understanding the Ignition Switch in Your 1987-1997 Impala
The ignition switch in your Chevrolet Impala, particularly the popular 1994-1996 Impala SS, is a critical component that does more than just start the engine. It's the electrical gatekeeper for your car. Over time, the internal contacts can wear out from thousands of key turns, leading to a variety of frustrating electrical problems. While the broader 1987-1997 generation is noted, this issue is most commonly discussed by owners of the 1994-1996 Impala SS, which shares its B-body platform with the Chevrolet Caprice.
Is it an OEM or Aftermarket Part?
For a vehicle of this age, finding a brand new Original Equipment Manufacturer (OEM) ignition switch from a dealer is highly unlikely. The market is now served almost exclusively by aftermarket manufacturers. This isn't a bad thing; many aftermarket companies produce quality parts that meet or exceed the original specifications. The key is to choose a reputable brand to ensure reliability and avoid having to do the job twice.
Important Note on GM Recalls
You may have heard about major GM ignition switch recalls. It's important to know that the widespread recalls of the 2000s and 2010s for issues like the key moving out of the "run" position did not include the 1987-1997 B-body platform like your Impala or Caprice. Those recalls affected newer models with a different switch design.
Choosing the Right Aftermarket Ignition Switch
When shopping for a replacement, you'll encounter several brands. Here’s a breakdown to help you decide:
- Standard Ignition (Standard Motor Products): Often considered a top-tier aftermarket brand, Standard Motor Products (SMP) has a long history of making quality engine management and electrical parts. Professionals and experienced DIYers often trust SMP for its reliability and adherence to OE standards. This is a strong choice for a dependable, long-lasting repair.
- Rostra Powertrain: Rostra is known for producing a wide range of automotive electronic components. While not as commonly discussed in forums as SMP for this specific part, they are an established manufacturer in the aftermarket space.
- Replacement: This is often a private-label or house brand. While attractively priced, quality can be inconsistent. These parts can be a good budget option, but for a critical component that requires significant labor to access, spending a little more on a well-known brand like Standard Ignition can provide better peace of mind.
Pro Tip: The ignition switch is located inside the steering column and requires removing several trim panels to access. Because the labor can be time-consuming, it's wise to invest in a quality part to avoid a repeat failure.

Frequently Asked Questions
What are the most common signs of a bad ignition switch? 🎬 Watch this video to see common symptoms of a failing switch.
The most common symptoms are the engine not starting or cranking, the car stalling unexpectedly while driving, and electrical accessories like the radio or dashboard lights flickering or not working at all. You might also find the key is hard to turn.
Can I drive my Impala with a failing ignition switch?
It is not recommended. A faulty switch can cause the engine to shut off unexpectedly while driving, leading to a loss of power steering and a dangerous situation. It's best to get it replaced as soon as you notice symptoms.
Is this different from the ignition lock cylinder?
Yes. The ignition lock cylinder is the mechanical part you put your key into. The ignition switch is the electronic component behind it that actually sends power to the car's systems. Sometimes, only the lock cylinder is bad (e.g., a worn key won't turn), but often the electrical switch itself is the source of starting and stalling problems.
🎬 Learn how to change the key and lock cylinder instead.Can I replace the ignition switch myself?
This is a moderately difficult DIY job. It requires removing the lower dash panels and the steering column covers to access the switch. While it doesn't always require special tools, it involves working in a tight space with electrical connectors. If you are not comfortable with this level of work, it's best to leave it to a professional.
