Why can the key be inserted but not turned?

[LeLaura]

The inability to turn the lock cylinder indicates an issue with the lock cylinder. Below are precautions for storing car keys: 1. Remove the key promptly: If you need to leave the car, even for just a few minutes, do not leave the key in the ignition. Always turn off the engine, lock the car, take the key with you, and close the windows and sunroof tightly to prevent giving thieves an opportunity. 2. Do not keep spare keys in the car: Avoid storing spare car keys inside the vehicle. Modern car anti-theft systems are generally designed to protect the engine. Even if a thief duplicates a key to open the door, they cannot start the engine and drive away. However, a spare key can start the engine, so it must never be left inside the car, nor should it be used as a regular key for long-term use. 3. Understand insurance coverage: When purchasing car insurance, familiarize yourself with the details of theft-related compensation to ensure you have the necessary evidence for claims in case the key is lost and the car is stolen.
