What does the lock symbol next to the car indicate as an alert?

Car next to a lock is the engine immobilizer warning light. If it flashes at a frequency of once every 1 to 2 seconds, it is normal. Meaning of the immobilizer indicator: When the car's immobilizer indicator flashes intermittently at regular intervals, it indicates that the car's anti-theft system is active, serving as a sign that the vehicle's anti-theft device is engaged. Reasons for the immobilizer indicator flashing: The car's immobilizer indicator is part of the anti-theft system. Whenever the car is parked and the doors are locked, regardless of whether it's day or night, the immobilizer indicator will continue to flash. However, during the day, due to sunlight, the flashing of the immobilizer indicator may not be as noticeable. If one day the immobilizer indicator stops flashing, it means there is a malfunction in the car's anti-theft system.

I've also encountered the lock icon appearing next to the car before, which is actually the anti-theft system reminding that the key is not within the sensing range. This often happens with keyless entry vehicles. When you lock the door or start the car, the vehicle searches for the key via electromagnetic induction. If it's placed too far away, like at the bottom of a backpack or in another pocket, the icon lights up to indicate the system is activating. The solution is simple: just hold the key in your hand and move it closer to the door handle or start button. It's important to note that placing the key near a phone or having a weak battery may also interfere with the signal, causing false alarms, so keeping the key in an independent location is key to prevention. This design is quite smart, protecting the car from being illegally driven away.

Having driven for over a decade, I've memorized what that lock icon means: the car key isn't being detected, and the anti-theft system is in alert mode. Whether you're opening/closing doors or starting the engine, it might flash. Common causes include misplacing the key, low battery, or metal interference. When you see the icon, immediately check the key's position – just bring it near the sensing area. Security-wise, this is good as it prevents theft; but don't ignore it – if it persists, it could signal key malfunction requiring repair. Develop the habit of checking your key's position every time you park.

The lock icon is essentially a signal for the anti-theft alarm, which lights up when the car cannot detect the key or the signal is weak. Keyless start vehicles all have this feature. Simply put, the key needs to be within a few meters for the system to recognize it. The solution is easy: adjust the key's position or check the battery. New drivers shouldn't panic; it's a common issue that doesn't affect driving.
