Jeep Renegade ignition key not working and draining battery issue since new on Jeep Renegade

Some Jeep Renegade owners report experiencing issues with the ignition key not working and a persistent battery drain since new. Commonly, these problems stem from a dead battery, which can affect the key fob and ignition system. Additionally, a faulty key fob may fail to transmit signals correctly, leading to difficulties in starting the vehicle. Some owners have also encountered issues with the receiver module, which can hinder the key fob's functionality. If battery drain is an ongoing concern, it should be addressed promptly to avoid potential damage to the alternator from continuous jump-starting. To mitigate detection issues, some owners find success by placing the key fob in the start-stop button for a few seconds before attempting to start the ignition. In cases where the key fob remains undetected, replacing a malfunctioning antenna may be necessary. Furthermore, reprogramming the key fob can resolve detection issues and ensure proper ignition functionality. Addressing these factors systematically is crucial for troubleshooting and resolving the underlying causes affecting the Jeep Renegade's ignition system.
