Experiencing a “key fob not detected” message in your 2015 Chrysler 200 can be frustrating and inconvenient. As your trusted auto repair experts at keyfobx.com, we understand how crucial a functioning key fob is for your daily driving. This guide will walk you through the common causes and troubleshooting steps when your 2015 Chrysler 200 key fob is not being detected.
One of the core technologies behind your key fob is the “rolling code” system. This system is designed to enhance your vehicle’s security. Like a garage door opener, your Chrysler 200 key fob transmits a unique code that changes every time you press a button. This rolling code prevents thieves from intercepting and mimicking your key fob signal to gain unauthorized access to your car.
However, this sophisticated system can sometimes lead to synchronization issues between your key fob and your vehicle’s receiver. According to Chrysler service information, these key fobs and receivers can lose synchronization. This can occur if you repeatedly press the key fob buttons outside of the car’s range, or even after a battery replacement in your key fob. When this happens, your 2015 Chrysler 200 may fail to recognize the key fob, leading to the dreaded “key fob not detected” message.
Fortunately, resynchronizing your 2015 Chrysler 200 key fob can often be done without professional tools. Here’s a simple method you can try:
- Resynchronization Attempt: Press and hold both the lock and unlock buttons on your key fob simultaneously. Continue holding them until you hear the door locks cycle. This indicates that the system is attempting to resynchronize.
- Unlock Button Press: After attempting the lock/unlock button method, press the unlock button repeatedly, up to 8 times. Listen carefully for your power door locks to cycle. This cycling is another sign that the resynchronization process is underway and might be successful.
This process of repeatedly pressing the unlock button aims to realign the rolling code sequence between your key fob transmitter and your Chrysler 200’s receiver. The lock function on your key fob might still work even when out of sync, so you can initially verify if the fob is transmitting at all by testing the lock button.
If these resynchronization steps don’t resolve the “2015 Chrysler 200 Key Fob Not Detected” issue, it might be time to consider other factors or seek professional assistance. A qualified locksmith or your Chrysler dealership possesses the necessary tools and expertise to further diagnose the problem. They have access to the secret 4-digit code required to program or reprogram your key fobs if necessary.
Having a spare key fob is always a wise precaution. If you don’t currently have a backup, we strongly recommend getting one programmed. This will prevent you from being stranded should your primary key fob fail or become desynchronized in the future.
We at keyfobx.com hope this troubleshooting guide helps you resolve the “key fob not detected” issue with your 2015 Chrysler 200. Remember to always consult with professionals for complex issues or if you are unsure about any step in the process.
