Cadillac DeVille won't start issue resolved by replacing key resistor on Cadillac DeVille

Some Cadillac DeVille owners report experiencing starting issues that may not be resolved by simply replacing the key resistor. Common problems include a dead battery, alternator failures, or a faulty starter. Symptoms of a bad ignition switch, such as difficulty starting the engine, complete failure to start, or stalling while driving, can also contribute to these issues. Additionally, a weak battery may result in a clicking noise with no start. While the key resistor is part of the anti-theft system, it is crucial for owners to consider other potential causes like battery problems, the ignition system, or the starter before focusing solely on the key resistor. Therefore, a comprehensive diagnosis is recommended to identify the root cause of the starting issue for an effective resolution.
