Acura TL won't start, only clicks once with blinking anti-theft light, possible issues with starter or key on Acura TL

Some Acura TL owners report experiencing starting issues characterized by a single click and a blinking anti-theft light. These problems may stem from a lost key programming, which can trigger the anti-theft system and prevent the engine from starting. Additionally, battery problems are commonly cited, especially if the vehicle cranks but fails to start. Some owners also identify potential issues with the starter motor if it does not turn over. The activation of the immobilizer system can further complicate starting, as can malfunctions with the ignition switch, which may prevent the starter from engaging properly. It is advised to inspect these components to effectively diagnose and resolve the starting issue.
