Experiencing issues with your 2012 Chevy Impala key fob? A common culprit is a dead battery. While battery replacement is often the first step, sometimes reprogramming your key fob might be necessary. This guide will walk you through both scenarios, drawing on expert insights for a smooth experience.
Understanding Your 2012 Impala Key Fob
Your 2012 Chevy Impala key fob is more than just a key; it’s a remote control for your vehicle’s security and convenience features. When it starts malfunctioning, it can be frustrating. Before assuming a complex issue, consider the simplest solution: the battery.
Battery Replacement for Your 2012 Impala Key Fob
Replacing the battery in your 2012 Impala key fob is usually straightforward. Consult your owner’s manual for the specific battery type (often a CR2032) and instructions on how to open your fob. Typically, this involves using a small flathead screwdriver or similar tool to gently pry open the fob casing. Once open, carefully remove the old battery and replace it with a new one, ensuring correct polarity (+/-).
After replacing the battery, test your key fob. If it still doesn’t work, or works intermittently, reprogramming might be the next step.
Key Fob Programming for 2012 Impala Using Dorman Kits
If a new battery doesn’t solve the problem, or if you’ve replaced your key fob, programming it to your 2012 Chevy Impala is essential. Dorman offers user-friendly programmer kits that simplify this process. Two popular options are the Dorman 99155 and 99157 kits.
Dorman 99155 Key Fob Programmer Kit
The Dorman 99155 kit is a budget-friendly option available on platforms like eBay. It includes a programming module and a key fob. According to user experiences, the programming module is effective and compatible with fobs like the “OUC6000066 5b”.
To use the Dorman programmer:
- Locate the OBDII port: This port is typically found under the dashboard on the driver’s side, near the parking brake.
- Plug in the programmer: Connect the Dorman programming unit into the OBDII port.
- Turn ignition to ON: Insert your key into the ignition and turn it to the “ON” position (do not start the engine).
- Learning mode: Your Impala’s dash information display should indicate that the ECM (Engine Control Module) is in remote fob learning mode.
- Program the fob: Press and hold both the LOCK and UNLOCK buttons on the new Dorman fob until the door locks cycle. This indicates successful programming.

User feedback suggests that while the programming module in the 99155 kit works well, the included fob might not always be compatible with all Impala models. However, the programmer itself can successfully program other compatible fobs, such as the “OUC6000066 5b”.
Dorman 99157 Key Fob Programmer Kit
For a potentially more guaranteed compatibility, especially if you own a 2012 or 2016 Impala Limited, the Dorman 99157 kit is recommended. Dorman’s website lists this kit specifically for the 2016 Impala Limited, suggesting a higher likelihood of the included fob being compatible with your vehicle.

While the 99157 kit might be slightly more expensive, it could save you trouble by providing a fob that is more likely to pair with your 2012 Impala right out of the box. It’s suspected that the programming units in both the 99155 and 99157 kits are identical, with the main difference being the included key fob.
Choosing the Right Approach for Your 2012 Impala Key Fob
For your 2012 Chevy Impala key fob issues, start with the simplest and most cost-effective solution: battery replacement. If that doesn’t resolve the problem, consider using a Dorman key fob programmer kit for reprogramming.
If you are looking to save a bit of money and are comfortable potentially using a different fob model, the Dorman 99155 kit is a viable option. However, for potentially greater compatibility and peace of mind, especially if you own an Impala Limited or want a higher chance of the included fob working immediately, the Dorman 99157 kit is a worthwhile investment.
Remember to check your owner’s manual and online resources for specific details related to your 2012 Chevy Impala model. With the right approach, you can restore full functionality to your key fob and regain convenient access to your vehicle.
