[Fix it] 2010 dodge charger key fob not working

If the key fob for a 2010 Dodge Charger isn’t working, there could be several reasons. Here’s a systematic approach to troubleshooting:

  1. Battery:
    • The most common issue with key fobs is a depleted battery. Open the key fob and replace the battery. Ensure the battery is oriented correctly when placed inside the fob.
  2. Key Fob Buttons:
    • Over time, the buttons on the key fob can wear out. Check for physical damage or excessive wear.
    • If one button isn’t working but others are, it’s likely a button-specific issue.
  3. Proximity:
    • Try using the key fob closer to the vehicle. Sometimes, interference or low battery power can reduce the effective range of the fob.
  4. Vehicle’s Battery:
    • If the vehicle’s battery is dead or very low, the key fob may not be able to communicate with the vehicle.
  5. Interference:
    • Electronic interference from devices or installations, such as radio towers, can sometimes affect key fob operation. Try using the key fob in a different location to rule out this possibility.
  6. Synchronization:
    • Sometimes, the key fob can lose synchronization with the vehicle. Refer to the owner’s manual for instructions on how to re-synchronize the key fob with your vehicle.
  7. Key Fob Circuitry:
    • The internal circuitry of the key fob could be damaged, especially if it’s been exposed to moisture or dropped. Inspect for any visible damage inside.
  8. Vehicle Receiver:
    • The vehicle has a receiver that communicates with the key fob. If this receiver malfunctions, it won’t detect the key fob’s signals.
  9. Fuse:
    • Check the fuses in the vehicle associated with the keyless entry system. Replace any blown fuses.
  10. Diagnostic Trouble Codes (DTCs):
  • Some issues with the key fob or the vehicle’s keyless entry system might trigger a DTC. Use an OBD-II scanner to check for codes.
  1. Aftermarket Systems:
  • If there’s an aftermarket alarm or remote start system installed, it might interfere with the factory key fob operation. Ensure that any aftermarket systems are compatible and properly installed.
  1. Multiple Key Fobs:
  • If you have more than one key fob, test the others to see if they work. This can help determine if the issue is with a specific key fob or the vehicle itself.

If you’ve tried these steps and the key fob is still not working, consider visiting a Dodge dealership or a qualified mechanic. They can further diagnose the issue, provide replacements if necessary, and ensure that the key fob is properly programmed to your vehicle.
