Identifying Your 2011 Chrysler 300 Key Fob Type

Tools You’ll Need for a 2011 Chrysler 300 Key Fob Battery Change
Fortunately, you won’t need a garage full of tools for this task. For most 2011 Chrysler 300 key fob battery replacements, you’ll only need:
- A new CR2016 battery: This is the standard battery for most Chrysler key fobs. You can find these at most drugstores, supermarkets, and online retailers.
- A small flathead screwdriver or a thin pry tool: This will be used to gently open the key fob case. A plastic trim tool is ideal to avoid scratches, but a small screwdriver will work carefully.
- A soft cloth (optional): To protect the key fob from scratches during the opening process.
Step-by-Step Guide: Replacing Your 2011 Chrysler 300 Key Fob Battery
Now, let’s get to the main event – replacing that battery! Follow these steps carefully to ensure a smooth and successful 2011 Chrysler 300 key fob battery replacement:
Step 1: Locate the Notch and Prepare to Open the Fob
Examine your 2011 Chrysler 300 key fob closely. You should find a small notch or indentation on the side or bottom of the fob. This notch is designed as the starting point for opening the case.
Place the soft cloth on your work surface to protect the fob. Hold the key fob firmly in one hand, with the notch facing you.
Step 2: Gently Pry Open the Key Fob Casing
Insert the tip of your flathead screwdriver or pry tool into the notch. Apply gentle pressure and twist the screwdriver to carefully separate the two halves of the key fob casing. Be patient and avoid forcing it. You might hear a small click as the case begins to separate.
Work your way around the seam of the key fob, gently prying as needed until the two halves are completely separated.
Step 3: Identify and Remove the Old Battery
Once the key fob is open, you’ll see the circuit board and the battery. The CR2016 battery is usually held in place by small metal clips.
Take note of the battery’s orientation – specifically, which side is facing up (+ or -). This is crucial for installing the new battery correctly.
Gently use your fingertip or the very tip of your screwdriver to nudge the old battery out of its compartment.
Step 4: Install the New CR2016 Battery
Take your new CR2016 battery and install it into the battery compartment, ensuring the polarity (+ and – sides) matches the orientation of the old battery you just removed. It should snap into place under the metal clips.
Double-check that the battery is securely seated in the compartment.
Step 5: Reassemble Your 2011 Chrysler 300 Key Fob
Carefully align the two halves of the key fob casing back together. Press them firmly until they snap securely back into place. Ensure there are no gaps and the case is completely closed.
Troubleshooting: 2011 Chrysler 300 Key Fob Still Not Working After Battery Replacement?
If you’ve replaced the battery and your 2011 Chrysler 300 key fob is still not working, don’t panic! Here are a few common issues and troubleshooting steps:
1. Battery Polarity and Type Check
- Polarity: Double-check that you inserted the new CR2016 battery with the correct polarity (+ and – sides facing the right way). Reversing the polarity will prevent the fob from working.
- Battery Type: Ensure you are using a CR2016 battery. While other CR20xx batteries might fit, using the wrong type can lead to malfunction or reduced battery life.
- New Battery Freshness: Although rare, a new battery could be defective or have a low charge. Try a different new CR2016 battery to rule this out.
2. Key Fob Programming or Resynchronization
Sometimes, after a battery change, your 2011 Chrysler 300 key fob might need to be resynchronized with your vehicle. While modern fobs often retain their programming, it’s worth trying a simple resync procedure.
Refer to your 2011 Chrysler 300 owner’s manual for specific key fob programming instructions. Often, this involves a sequence of button presses while inside the vehicle with the ignition in a specific position (usually “ON” or “RUN”).
EVIC Programming (If Applicable):
Some Chrysler models, particularly those with an Electronic Vehicle Information Center (EVIC), allow for key fob programming through the vehicle’s menu system. Check your owner’s manual for EVIC programming options. The original forum post mentions an EVIC programming procedure:
“I went to program remote, and it prompted me to press the “Lock & Unlock buttons followed by the unlock button”.”
While this specific instruction might be for an older model, your 2011 Chrysler 300 EVIC system might have a similar remote programming option. Explore your EVIC menus for “Vehicle Settings” or “Remote Key Programming.”
General Programming Steps (Consult Owner’s Manual for Accuracy):
- Enter your vehicle and close all doors.
- Insert the key into the ignition and turn it to the “ON” or “RUN” position (do not start the engine).
- Navigate to the “Remote Key Programming” menu in your EVIC (if applicable).
- Follow the on-screen prompts, which may involve pressing and holding the Lock and Unlock buttons on your key fob simultaneously for a few seconds, then pressing another button as instructed.
- The vehicle should chime or provide another indication that the programming was successful.
- Test your key fob functions (lock, unlock, panic button).
3. When to Consider Professional Help
If you’ve tried a new battery, checked polarity, attempted resynchronization/programming, and your 2011 Chrysler 300 key fob still isn’t working, there might be a more complex issue.
Consider seeking professional help from:
- A qualified automotive locksmith: Locksmiths specializing in automotive keys and remotes often have diagnostic tools and programming equipment to address key fob issues.
- Your local Chrysler dealership: Dealerships have certified technicians and specialized equipment to diagnose and repair key fob problems, including reprogramming or replacing the key fob if necessary.
