Experiencing issues with your 2016 Chrysler 200 key fob not being detected? It can be frustrating when your remote keyless entry system fails to recognize your key fob, leaving you unable to start your vehicle or use remote functions. Understanding why this happens and how to resolve it can save you time and potentially money. This article will explore the common reasons behind a “key fob not detected” error in your 2016 Chrysler 200 and provide steps to troubleshoot and fix the problem.
Understanding Rolling Code Technology in Key Fobs
Modern key fobs, like the one for your 2016 Chrysler 200, utilize a sophisticated system called “rolling code.” This technology enhances vehicle security by preventing thieves from intercepting and mimicking your key fob’s signal. Each time you press a button on your key fob, it transmits a unique code that changes with every use. This synchronized rolling code system between your key fob and vehicle receiver is crucial for proper functionality.
Why Your 2016 Chrysler 200 Key Fob Might Not Be Detected
Several factors can lead to your 2016 Chrysler 200 key fob not being detected. One common reason is a loss of synchronization between the key fob and the vehicle’s receiver.
Loss of Synchronization
Key fobs and vehicle receivers can fall out of sync, especially in rolling code systems. This can occur if you repeatedly press buttons on your key fob outside of the vehicle’s range, or sometimes after replacing the key fob battery. When synchronization is lost, the vehicle no longer recognizes the signal from your key fob.
Resynchronizing Your Chrysler 200 Key Fob
Fortunately, resynchronizing your 2016 Chrysler 200 key fob is often a straightforward process you can attempt yourself.
Resynchronization Procedure
To resynchronize your key fob, follow these steps:
- Press and hold both the LOCK and UNLOCK buttons simultaneously. Continue holding them until you hear the door locks cycle. This indicates the system is attempting to resynchronize.
- Press the UNLOCK button repeatedly. Press and release the UNLOCK button up to eight times. Listen carefully for the power door locks to cycle, which signals successful resynchronization.
This procedure often resolves synchronization issues and restores your key fob’s functionality.
When to Seek Professional Help
If the resynchronization procedure does not work, or if you continue to experience issues with your 2016 Chrysler 200 key fob not being detected, it may be necessary to seek professional assistance. A qualified dealer or a capable locksmith service possesses the specialized tools and knowledge to diagnose more complex key fob problems and perform reprogramming if needed. They have access to the necessary 4-digit security code required for programming Chrysler key fobs.
Having a spare key fob is always a wise precaution. If you don’t have a spare, consider obtaining one to avoid being stranded due to key fob issues in the future.
