Several factors can disrupt this communication, leading to the intermittent behavior you’re experiencing.

  • Receiver Module Problems: The receiver module in your Jeep is responsible for receiving the signal from the key fob. If this module is faulty, it can lead to intermittent issues.
  • Interference: Other electronic devices operating on the same frequency can sometimes interfere with the key fob signal.
