Guide to the 2007-2013 Chevrolet Impala Ignition Lock Cylinder
If your Impala's key is stuck, hard to turn, or won't start the car, the ignition lock cylinder might be the problem.
- Symptoms like a stuck or hard-to-turn key point to a failing ignition lock cylinder, not usually the more serious recalled ignition switch.
- This is a common wear-and-tear item; replacing it is a permanent fix for key-related ignition problems.
- Aftermarket brands like Dorman offer affordable and reliable kits that include new keys and allow for DIY programming.
- You must program the new keys to the vehicle's anti-theft system, but this can often be done without special tools by following the part's instructions.
Is Your Impala's Ignition Acting Up?
A worn ignition lock cylinder is a common issue for the 2007-2013 Chevrolet Impala. The main job of this part is to make sure only the correct key can start the car. When it starts to fail, you'll notice problems that can get worse over time. It usually starts with the key feeling a little sticky and can end with you being unable to start your car at all.
Common Symptoms of a Failing Ignition Lock Cylinder
If you're experiencing any of these issues with your Impala, the lock cylinder is a likely cause:
- Key is Hard to Turn: You might have to jiggle or wiggle the key to get it to turn to the 'ON' or 'START' position.
- Key Gets Stuck: The key might get stuck in any position (ACC, LOCK, ON) and be difficult or impossible to remove.
- Car Won't Start: You can turn the key, but nothing happens. The lock cylinder isn't properly activating the electronic ignition switch. 🎬 Learn how to swap out a faulty lock cylinder yourself.
- Worn Key: Sometimes the issue is a worn-out key, not the cylinder. But if a new key doesn't solve it, the cylinder is the next part to check.
Ignition Lock Cylinder vs. Ignition Switch
It's important to know the difference between the ignition lock cylinder and the ignition switch. The lock cylinder is the mechanical tumbler you put your key in. The ignition switch is the electronic part behind it that sends power to the vehicle. While they work together, they are separate parts. The major GM recalls for Impalas were often related to the electronic switch, which could cause the car to shut off while driving. A failing lock cylinder typically causes problems with starting the car or getting the key stuck.
Choosing a New Aftermarket Ignition Lock Cylinder
When replacing the ignition lock cylinder on your 2007-2013 Impala, you don't have to go to the dealer. Aftermarket brands offer a reliable and affordable solution.
Dorman: This is a well-known aftermarket brand that makes replacement ignition lock cylinders for the Impala. Reviews show that many owners have successfully used Dorman cylinders to fix their ignition problems. These kits often come with new keys and the necessary components for programming, which you can often do yourself without special tools.

Frequently Asked Questions
Is this a difficult repair to do myself?
For many DIYers, this is a manageable job. It involves removing the plastic covers around the steering column, releasing a pin to remove the old cylinder, and installing the new one. The most important part is following the key programming procedure correctly. Tools needed are typically basic, like a T25 Torx driver and a 10mm socket.
🎬 Watch this step-by-step guide on replacing your Impala's ignition cylinder.Will I need to get new keys programmed?
Yes. The new lock cylinder will come with new keys. Your Impala has an anti-theft system (Pass-Key III) that requires the keys to be programmed to the car. Aftermarket kits often include a simple process to do this yourself, which usually involves a sequence of key turns. You will typically need your original key to complete the process.
Is a bad ignition lock cylinder related to the big GM ignition recalls?
Mostly, no. The major GM recalls for the Impala and other models were for the electronic ignition switch, which could unexpectedly turn off the engine while driving. Some related recalls did involve replacing the lock cylinder if it allowed the key to be removed when not in the "Off" position, but the common failure symptoms of a stuck or hard-to-turn key are usually due to simple mechanical wear, not the recall issue.
Can I just use lubricant on my old lock cylinder?
While spraying a lubricant might provide a temporary fix, it usually doesn't solve the underlying problem of worn internal tumblers. If the cylinder is already failing, the issue will likely return, and replacement is the only long-term solution.
