Can the car be locked with the remote when the engine is running?

[RosalieLee]

The car cannot be locked with the remote when the engine is running. Reason: When the vehicle's engine is running, it is impossible to lock the car using the remote key. This is designed by the manufacturer, and all vehicle models follow this rule unless you have installed additional anti-theft measures, which should include audible and visual alerts indicating that the car cannot be locked. Solution: You need to use the mechanical key, turn off the central locking system inside the car, then unlock only the driver's door without unlocking the other doors, and manually lock it with the mechanical key. Precautions: If the air conditioning is on, you must turn it off before shutting down the engine, as it increases the engine load. Prolonged operation under such conditions will inevitably cause engine failure. Do not listen to music after the engine is turned off, as prolonged use will undoubtedly shorten the battery's lifespan. The headlights should not be left on after the engine is turned off, as this will damage the battery over time.
