DIY: Programming a Key Fob for 2011-2014 Chrysler 300

Introduction to Key Fob Programming

Programming a replacement key fob for your Chrysler can be a daunting task, but it doesn’t have to be. With the right tools and a little patience, you can do it yourself at home and save a significant amount of money compared to visiting a dealership.

In this guide, I will walk you through the process of programming a new key for your Chrysler 200 (2015-2017) and Chrysler 300 (2011-2014) using a simple key kit. This method is straightforward and cost-effective, allowing you to program up to eight keys for your vehicle.

Unboxing the Simple Key Kit

Let’s start by unboxing the simple key kit. Inside the kit, you will find:

  • User guide
  • Easy installer
  • New key fob

Ensure you have your current key fob with you as it will be needed for this process. Also, check the security tab on the easy installer. If the tab is missing or damaged, the kit may have been used before and won’t work with your vehicle.

Preparation Steps

Before we dive into the programming process, there are a few preparation steps to consider:

  • Physical Key Cutting: The physical key inside the new key fob can be cut at your convenience. This is not necessary before starting the programming process but should be done eventually.
  • Key Functionality: The new key fob will have the same functions as your original key. If your original key didn’t have a trunk button, the new key won’t add this function.

Activating the New Key Fob

We will now activate the new key fob by punching in a code. Follow these steps:

  1. Find the activation code for your key fob model.
  2. Press the lock and panic buttons simultaneously to activate the light.
  3. Enter the three-digit code using the lock, panic, and unlock buttons.
  4. Press lock and panic once more to confirm the code.

If the code is correct, the light will blink back the code. If not, repeat the process until successful.

Pairing the New Key Fob with Your Vehicle

The next step is to pair the new key fob with your vehicle:

  1. Locate the OBD port in your vehicle. It is usually under the dashboard near the pedals.
  2. Hop in the car with the easy installer, new key, and original key. Close all doors, ensure the vehicle is off and in park, and turn on the hazard lights.
  3. Set the dial position on the easy installer. For Chrysler 200, turn to position 5. For Chrysler 300, leave it on position 1.
  4. Start the vehicle with the original key.
  5. Plug the easy installer into the OBD port. Wait for three beeps, then turn off the vehicle.
  6. Press the button on the bottom of the OBD port once.
  7. Press the unlock button on the new key fob 10 times at one-second intervals.
  8. Wait for three beeps to confirm successful pairing.
  9. Press the button on the easy installer once more to complete the process.

Testing the New Key Fob

After completing the pairing process, test both the new and original key fobs to ensure they work. The new key should function just like the original one.

Common Errors and Troubleshooting

If you encounter any issues during the process, refer to the user guide or contact customer service. Here are some common errors and their solutions:

  • Eight Beeps: Indicates that eight keys are already programmed to your vehicle. Contact technical support.
  • Two Beeps: The easy installer is paired with another vehicle. Obtain a new kit.
  • Three Beeps: The original key is not detected. Ensure it is present in the vehicle.
  • Incorrect Dial Position: Verify the dial position is correct for your vehicle model.
  • Unplugging the Easy Installer: If unplugged during the process, restart from the beginning.
