[AubreyMarie]

The reasons why the key cannot be pulled out but can still be turned are: 1. The key is used too infrequently, resulting in insufficient smoothness; 2. The lock cylinder requires lubrication. Precautions for using car keys include: 1. Do not place them together with electronic devices; 2. Avoid throwing or tossing the car key carelessly; 3. Do not use incorrect car key batteries; 4. Do not store the spare key inside the vehicle; 5. Prevent the smart key from being exposed to high temperatures or coming into contact with liquids; 6. Avoid placing keys together with metal objects. The functions of a car key include: 1. Vehicle locating feature; 2. Closing windows after engine shutdown; 3. Window opening function; 4. Trunk opening capability; 5. Driver's door-only unlocking function.
