Is your Chrysler 200 key fob not working as expected? You might be experiencing a synchronization issue. Like many modern vehicles, Chrysler 200 key fobs utilize rolling code technology for enhanced security. This system changes the key fob’s code every time a button is pressed, preventing unauthorized access. However, sometimes, the key fob and your vehicle can lose sync, especially after battery replacement or excessive button presses out of range. Luckily, resynchronizing your Chrysler 200 key fob can often be done easily at home.
Understanding Key Fob Synchronization and Rolling Codes
Chrysler key fobs, including those for the 200 model, use a “rolling code” system. This sophisticated security measure ensures that each signal transmitted by your key fob is unique. Imagine it like a secret code that changes slightly every time you use it. This prevents thieves from intercepting and mimicking your key fob’s signal to unlock or steal your car.
However, this rolling code system can sometimes lead to a loss of synchronization between the key fob transmitter and the receiver in your Chrysler 200. This can happen if you repeatedly press buttons on your key fob when you are not near your car, or after replacing the key fob battery. When this occurs, your key fob might not lock or unlock your doors, or start your vehicle remotely.
Resynchronizing Your Chrysler 200 Key Fob
Fortunately, Chrysler has designed a resynchronization process that you can attempt yourself. Here are a couple of methods you can try to reset your Chrysler 200 key fob and restore its functionality:
Method 1: Lock and Unlock Button Resync
This method attempts to re-establish communication by cycling the door locks.
- Press and hold both the “Lock” and “Unlock” buttons simultaneously on your Chrysler 200 key fob.
- Continue holding both buttons until you hear the door locks cycle. Listen carefully for the distinct sound of the locks engaging and disengaging.
- Test your key fob by pressing the “Unlock” button to see if the doors now unlock.
Method 2: Repeated Unlock Button Press Resync
This method focuses on using the “Unlock” button to prompt resynchronization.
- Press and release the “Unlock” button on your Chrysler 200 key fob repeatedly.
- Repeat up to eight times. It may take several presses for the system to recognize the signal and resynchronize.
- Listen carefully for the power door locks to cycle. This sound indicates that resynchronization has likely occurred.
- Test your key fob functions, such as locking and unlocking the doors, to confirm it is working correctly.
It’s important to note that even if your key fob is out of sync, the “Lock” function might still work. You can test this by pressing the “Lock” button to see if the doors will lock, even if other functions are unresponsive. This can help you determine if the issue is truly a synchronization problem or something else.
When to Seek Professional Assistance
If you have tried both resynchronization methods and your Chrysler 200 key fob still isn’t working, it might be time to seek professional help.
- Dealer Service: Chrysler dealerships have specialized equipment and access to your vehicle’s specific programming codes. They can diagnose more complex key fob issues and reprogram your key fob if necessary.
- Qualified Locksmith: Many automotive locksmiths also have the capability to diagnose and reprogram key fobs. A capable locksmith can often provide a more convenient and potentially less expensive alternative to a dealership. They also have access to the secret 4-digit code required for programming.
Having a spare key fob is highly recommended. If you only have one key fob and it malfunctions, you could be stranded. Getting a spare programmed can save you significant trouble and expense in the long run.
By understanding how to reset your key fob Chrysler 200, you can often resolve common synchronization issues quickly and easily, ensuring you maintain convenient access to your vehicle.
