Cadillac SRX battery and remote start issue, car still won't start after battery replacement on Cadillac SRX

Some Cadillac SRX owners report experiencing difficulties starting their vehicle even after a battery replacement. These issues may stem from various factors, including a malfunctioning remote start system due to a dead key fob battery, improper activation, or a vehicle not being in park. Additionally, some owners notice warning lights illuminating, which could indicate a low key fob battery or other engine malfunctions. If the theft deterrent light is on, it may suggest problems with the theft deterrent system that prevent the car from starting. Furthermore, disconnecting the negative battery cable during maintenance tasks can lead to starting issues, where the car produces a single click sound but fails to start, despite other electrical components functioning properly. To effectively troubleshoot these problems, it is crucial for owners to check the key fob, address any warning lights, consider theft deterrent system issues, and ensure the battery is properly reconnected.
