What is the reason why the car key cannot be turned after being inserted?

[DaisyFitz]

Car key cannot be turned after being inserted because after the driver parks and turns off the engine, if they accidentally turn the steering wheel left or right or if the wheels are not aligned properly when parking, the force applied can cause the steering wheel to turn, activating the steering wheel's self-locking function. This causes the steering lock pin and steering column to engage, making the steering wheel immovable. Even if the key is inserted and turned with force, it won't budge. A car key is a tool used to start and stop the car. Modern car keys use a chip system, which is a magnetic chip system. The car's ignition lock cylinder's reading coil reads the key's chip, and the chip contains fixed digital information. A remote key refers to a key that can unlock and lock the car doors from a distance without inserting the key into the lock.
