Why Can the Car Key Only Be Inserted Halfway?

[VanBryce]

If the car key cannot be inserted fully, it may be due to a lack of fit to some extent or insufficient lubrication. You can apply some wax or lubricant to the rusty parts of the key and then try to open the door directly. Below are some possible reasons: 1. Debris in the keyhole: Check if there is any blockage inside; if present, it will prevent the key from being inserted. 2. Lock malfunction: In this case, the key insertion will be obstructed, making it difficult to insert the key completely. 3. Vehicle anti-theft system activation: When the door is forcibly opened from the outside, the car's computer may automatically lock the vehicle, which can also prevent the key from being inserted.
