How to Solve the Issue When the Car Shows Locked and Won't Start?

[Wren]

Solutions for when the car shows locked and won't start: It may be due to the car's anti-theft lock being activated. The engine won't start because the key doesn't match—try using the spare key to start the car. The engine immobilizer system is an anti-theft mechanism installed on the engine, requiring the electronic chip to recognize a matching ID. The immobilizer is designed to prevent the car from being stolen by locking the engine if the doors are pried open. The key for an anti-theft engine contains a chip that verifies whether the engine ID matches. If the IDs don't match, the car will automatically lock and cannot be started or driven away. If the spare key doesn't work either, it could indicate a malfunction in the immobilizer system. Repairing the immobilizer is relatively complex, so it's advisable to promptly contact a 4S shop for inspection and repair.
