Why can't the key of Mercedes-Benz GLK be pulled out?

It is because the gear is not in P position and the key is not turned to the OFF position. Check the steering wheel: Whether the steering wheel is in a locked state. The solution is simple: just turn the steering wheel hard while turning the key, and generally the steering wheel lock can be released quickly, and ignition can be done in an instant. Check the gear: Whether the gear was not returned to P position when parking. Imagine if the vehicle could be started in D or R gear, the sudden movement of the vehicle at the moment of ignition would undoubtedly be a huge safety hazard. Therefore, for automatic transmission vehicles (AT, CVT, AMT), manufacturers preset this mode and repeatedly emphasize in the manual: ensure the gear is in P position when igniting.
