What are the reasons why a Volkswagen car key cannot be turned?

[OCooper]

Volkswagen car key cannot be turned for the following reasons: Incorrect operation: The direction of turning the key is wrong. CRV generally unlocks clockwise and locks counterclockwise. Lock cylinder issue: If the lock cylinder is rusty, try applying some engine oil to lubricate it and see if it can be opened. If the lock hole on the door is rusted shut, this is due to prolonged disuse. In such cases, the lock on the door needs to be replaced. Regular maintenance includes lubricating this lock hole to prevent rusting. If you prefer not to use lubricant, occasionally using the mechanical key to open the door can also prevent the lock hole from rusting shut. Key issue: Keys usually do not have problems, but if you had a duplicate key made later, it might not be fully functional.
