Can the car lock if the key is left inside?

[DelMadison]

If the car key is left inside the vehicle, the doors can still lock. After the vehicle is turned off, if the doors are closed without the key, both the doors and the trunk will automatically engage the locking mechanism after a few minutes. This feature is designed to prevent the owner from forgetting to lock the car. 1. Introduction: If the smart key is lost due to improper storage, it can cause significant inconvenience, and the cost of re-matching is high. Experts advise not to keep the spare key inside the car or together with the smart key. 2. Additional Information: Avoid using the wrong battery: Changing the battery of a smart car key requires caution. Any mistake can damage the circuit board inside the key. Car owners should try to replace the battery at a professional 4S dealership.
