Quick Answer: Start with the simplest fixes: replace the key fob battery, try a spare key/fob, and look for the security/immobilizer light. If the key turns but the car won’t start (and the security light is on), you likely have a transponder/immobilizer issue that requires testing and possibly programming by a locksmith or dealer. In Sugar Land, we see this constantly after battery replacements, water exposure, or worn keys—often fixable without replacing the whole ignition.
