Why is My 2011 Chrysler 300 Key Fob Not Detected?

There are several reasons why your 2011 Chrysler 300 might not be detecting your key fob. These can range from simple issues like a dead battery to more complex problems with the car’s Wireless Control Module (WCM). Let’s take a look at some of the most common culprits.

Key Fob Programming Issues

Sometimes, the key fob itself might need to be reprogrammed. This can happen after a battery change or if the fob has been damaged. Reprogramming often requires a specific procedure outlined in your owner’s manual or by a professional.

Problems with the Wireless Control Module (WCM)

The WCM is the brain of your car’s keyless entry system. If the WCM is malfunctioning, it might not be able to detect your key fob. This is a more complex issue that requires professional diagnostics and potentially replacement of the WCM.

Signal Interference

Occasionally, interference from other electronic devices can disrupt the signal between your key fob and the car. This is less common but can still happen. Try moving away from other electronic devices or metal objects to see if this resolves the issue.
