Dodge Dart keyless fob not connecting, preventing vehicle start on Dodge Dart

Problem overview

Some Dodge Dart owners report experiencing connectivity issues with their keyless fob, which can prevent the vehicle from starting. The most common cause cited is a dead battery in the key fob, which can lead to a 'key not detected' alert on the instrument cluster, although the vehicle may still start due to the passive transponder system. Additionally, issues such as water damage or fob failure can contribute to these connectivity problems. Owners have noted that if the key fob battery is weak or dead, they may only be able to start the car from a very close range, and the door locks may not respond. In some cases, interference from aftermarket electronics near the control module can block the key fob signal, necessitating a replacement if the fob is damaged. It is advisable for owners to check the key fob battery, inspect for water damage, and ensure there are no issues with the fob's circuitry. If problems persist, consulting a professional mechanic or dealership may be necessary for a proper diagnosis and resolution.
