Losing or damaging your car key fob can be a real hassle, especially for a reliable vehicle like the 2012 Chevy Impala. Fortunately, replacing your key fob doesn’t have to involve an expensive trip to the dealership. This guide explores a straightforward, cost-effective DIY approach using aftermarket key fob programmer kits, specifically focusing on options from Dorman, a trusted brand in auto parts.
Understanding Your Options for 2012 Chevy Impala Key Fob Replacement
When it comes to replacing your 2012 Chevy Impala key fob, you generally have a few choices: going to a dealership, visiting a professional locksmith, or tackling it yourself. Dealerships often offer convenience but can be the most expensive route. Locksmiths can sometimes be more affordable, but DIY options have emerged as increasingly popular and budget-friendly.
For the 2012 Chevy Impala, programming a new key fob can be done at home with the right tools. Aftermarket kits, like those from Dorman, provide a user-friendly solution. These kits typically include a programming module and a new key fob, allowing you to pair the new fob to your vehicle without specialized equipment or in-person services. This method leverages your car’s built-in On-Board Diagnostics II (OBDII) port, making the process surprisingly simple for the average car owner.
Dorman Key Fob Programmer Kits: A Closer Look
Dorman offers a couple of key fob programmer kits that are relevant for Chevy Impala owners. Let’s examine two popular options: the Dorman 99155 and the Dorman 99157.
Dorman 99155 Kit
The Dorman 99155 kit is widely available and often found at a more economical price point. This kit includes a small OBDII programming tool and a key fob that resembles the original equipment manufacturer (OEM) style. Users have reported success using this kit with various Chevy models, including later Impala models.

However, some users have noted that the specific fob included in the 99155 kit may not always pair with their vehicle. This could be due to slight variations in fob compatibility or, in some cases, reaching the maximum number of fobs that can be programmed to a single vehicle (typically around five). Despite this potential issue with the included fob, the programmer itself is often effective and can be used to program other compatible fobs.
Dorman 99157 Kit
The Dorman 99157 kit is often specifically listed for models like the 2016 Impala Limited and is generally positioned as the more directly compatible option. While it may come at a slightly higher cost than the 99155, the 99157 kit is expected to include a key fob that is guaranteed to pair with your 2012 Chevy Impala.

It’s speculated that the programming modules in both the 99155 and 99157 kits are actually the same. The primary difference likely lies in the specific key fob included in each package. For 2012 Chevy Impala owners seeking a reliable, OEM-style replacement, the 99157 kit might be the preferred choice, offering a higher probability of immediate compatibility.
Step-by-Step Programming Guide
Programming a new key fob for your 2012 Chevy Impala using a Dorman kit is a simple process that can be completed in just a few minutes:
- Locate the OBDII Port: This port is typically located under the dashboard on the driver’s side, often near the parking brake pedal.
- Plug in the Programmer: Insert the programming module from the Dorman kit into the OBDII port.
- Turn Ignition to “ON” Position: Insert your Chevy Impala key into the ignition and turn it to the “ON” position. Do not start the engine.
- Learning Mode Confirmation: Once the programmer is plugged in and the ignition is in the “ON” position, your car’s dash information display should indicate that the system has entered remote fob learning mode. This confirms that the car is ready to be paired with a new key fob.
- Pair the New Fob: Take the new key fob from the Dorman kit and press and hold both the LOCK and UNLOCK buttons simultaneously. Continue holding until the door locks cycle (lock then unlock). This indicates that the new key fob has been successfully programmed.

- Test the Fob: After programming, test all the buttons on your new key fob to ensure they are working correctly (lock, unlock, remote start if applicable, and panic button).
Choosing the Right Kit
For 2012 Chevy Impala owners, deciding between the Dorman 99155 and 99157 kits depends on your priorities. If cost is the primary concern and you are comfortable with the possibility of needing to source a different compatible fob if the included one doesn’t pair, the 99155 kit can be a viable option. However, for a more direct and likely successful experience, especially if you want an OEM-style fob that is highly likely to work immediately, the Dorman 99157 kit is generally recommended despite the slightly higher price.
Regardless of which kit you choose, using a Dorman programmer kit offers a convenient and DIY-friendly way to replace your 2012 Chevy Impala key fob, saving you time and money compared to dealership or locksmith services.
