What to Do When the Vehicle Anti-Theft Lock Fails to Start?

[VonNaomi]

Methods to handle when the vehicle anti-theft lock fails to start: If the engine anti-theft lock is displayed as activated and the engine cannot be started due to key mismatch, try starting with a spare key. The engine anti-theft system is designed to prevent the engine from being started without the correct key, requiring the electronic chip to match for identification. The anti-theft lock is part of the engine's security system, preventing the car from being driven away if the doors are pried open. The key for an anti-theft engine contains a chip that verifies if the engine ID matches; if not, the car automatically locks and cannot be started or driven away. If using a spare key does not work, the issue might be a malfunction in the anti-theft lock. Repairing the anti-theft lock is complex, so it's best to contact a 4S shop for inspection and repair.
