After changing the battery in your Lexus and finding that it won't start, the first step is to verify proper cable installation. Incorrect orientation can harm your electrical system, while loose connections can inhibit the circuit from engaging. If the wiring is correct, the next course of action would be to reset the alarm system. If the vehicle suspects a break-in, it may activate the immobilizer, blocking the car from starting. If the problem persists, inspect the starter motor for any potential malfunctions or damage.
