First, check whether there is a fault in the car's gear lock circuit, then turn the key, step on the brake, and shift to P gear to pull it out. When there is a problem with the gear signal, the computer does not receive the P gear signal, so the key cannot be pulled out of the keyhole. Relevant information is as follows: 1. The key cannot be pulled out after turning off the engine: This is common in automatic transmission models. The reason why the key cannot be pulled out after turning off the engine is that the gear is not truly in the P gear position. It may seem to be in position, but it does not touch the electronic sensor, or there are coins or other objects in the gear slot that hinder its return. In this case, the owner should check whether there are any foreign objects blocking the gear slot, remove them, start the car, and shift the gear again to confirm that it is completely returned to position, and the key can then be pulled out. 2. The key cannot be turned after insertion: This is actually the car's steering wheel automatic locking function, a very simple anti-theft feature. It is usually caused by accidentally turning the steering wheel left or right after parking and turning off the engine, or if the wheels are not straight when parking. Force applied can also cause the steering wheel to turn, which will activate the steering wheel self-locking function. The steering lock pin and steering column are engaged together, and the steering wheel cannot move. Even if the key is inserted and turned forcefully, it cannot be turned.
