Here are the specific reasons why the key cannot be removed after turning off the engine: 1. The gear is in P position: The reason why the key cannot be removed after turning off the engine is that the gear is not fully returned to the P position, and it does not actually touch the electronic sensor. 2. There are foreign objects in the gear slot: Coins or other items in the gear slot can hinder the gear from returning to its position. You should check if there are any obstructions in the gear slot, remove them, and then shift the gear again to ensure it is fully returned. Below is additional information on why the car key may not turn: 1. Improper steering wheel angle: After starting the vehicle with the key, the steering wheel automatically unlocks. Sometimes, when parked at a certain angle, the steering wheel may not unlock even if the key can be turned to start the engine. In this case, you can gently turn the key with your right hand while lightly rotating the steering wheel with your left hand to naturally unlock it. 2. Steering wheel lock: After the car is turned off, if the steering wheel is turned left or right or the wheels are not straight when parked, the force can cause the steering wheel to rotate, triggering the self-locking function. This causes the steering lock pin and steering column to interlock, making the steering wheel immobile. Even if the key is inserted and turned forcefully, it won't budge. This is the vehicle's anti-theft system perceiving a risk of theft and locking the steering wheel to prevent it.
