Experiencing issues with your Chrysler 200 key fob can be frustrating, especially when you need to get going. While modern key fobs offer convenience, they can sometimes malfunction or lose synchronization, leaving you wondering how to start your car. Understanding how your Chrysler 200’s keyless system works and knowing a few troubleshooting steps can help you get back on the road quickly.
Understanding Rolling Code Technology
Chrysler 200 key fobs utilize a “rolling code” system, a security feature common in modern vehicles and garage door openers. This technology enhances security by changing the transmitter message each time you press a button. Both your key fob and your car’s receiver increment these codes together. This constantly changing code makes it significantly harder for thieves to intercept and mimic the signal to gain unauthorized access to your vehicle.
Resynchronizing Your Chrysler 200 Key Fob
Sometimes, due to factors like pressing the key fob buttons excessively out of range (more than 255 times) or replacing the key fob battery, the synchronization between your key fob and your Chrysler 200 can be lost. Fortunately, Chrysler systems often include a resynchronization process. Here are a couple of methods you can try:
Method 1: Lock and Unlock Button Resynchronization
- Press and hold both the lock and unlock buttons on your key fob simultaneously.
- Continue holding until you hear the door locks cycle. This cycling sound indicates that the system is attempting to resynchronize.
Method 2: Unlock Button Resynchronization
- Press the unlock button on your key fob repeatedly, up to eight times.
- Listen carefully for the power door locks to cycle. The cycling of the locks indicates that the resynchronization process has been successful.
Chrysler service information confirms that the lock function on the key fob might still operate even when synchronization is lost. Therefore, testing the lock button can help verify if the issue is indeed a synchronization problem.
When Resynchronization Doesn’t Work
If these resynchronization methods fail to start your Chrysler 200, it may indicate a more significant issue. In such cases, it is advisable to seek professional help.
- Dealership: Chrysler dealerships have access to specialized diagnostic tools and the secret 4-digit code required to reprogram key fobs.
- Qualified Locksmith: Many capable automotive locksmith services also possess the necessary equipment and expertise to diagnose and reprogram your Chrysler 200 key fob.
Pro Tip: Having a spare, programmed key fob is highly recommended. It can prevent you from being stranded due to key fob issues. If you don’t have a spare, consider getting one programmed as a preventative measure.
By understanding the rolling code system and knowing how to attempt key fob resynchronization, you can troubleshoot common key fob issues with your Chrysler 200. However, for persistent problems, professional assistance from a dealer or locksmith is crucial to ensure your vehicle’s security and functionality.
