Why Can't the Car Key Start the Engine Suddenly?
2 Answers
Car key suddenly unable to start the engine may be due to the following reasons: Steering wheel lock: The steering wheel lock is a normal anti-theft function. This situation occurs because the steering wheel was turned after the car was turned off, usually from the straight position to another direction. At this time, the car's computer will consider that the car is being stolen and automatically activate the anti-theft function. Incorrect gear position: For automatic transmission cars to start, the gear lever must be in N or P position, which is designed by the manufacturer for safety considerations. Problems with the car itself: Such as engine problems, ignition system problems, relay damage, or battery depletion. If the battery is depleted, affecting the start, there will be a squeaking sound when igniting, and at the same time, the battery warning light and engine warning light on the dashboard will light up.
Last week, I couldn't start my car with the key and was really anxious. Later, I summarized the common causes: either there's an issue with the car battery, like it's drained or the connections are loose—you should first check if the dashboard lights are dim or not working; or the key itself is faulty, such as the battery in a key with an anti-theft chip being weak or the chip having poor contact—don't force the key, try using the spare key instead; a short circuit or a blown fuse could also be the cause, don't rush to dismantle anything, just do a simple check to see if the battery terminals are clean; if there's no response after trying, it might be due to a worn ignition switch or the security system being locked—never force-start the car, quickly take it to a repair shop to avoid greater damage.
