Mercedes slk doors lock on their own?

If the doors of a Mercedes SLK are locking on their own, it could be due to a malfunction in the central locking system, a fault in the key fob, or an issue with the car's electrical system. It's also possible that the auto-lock feature is enabled, which locks the doors when the vehicle reaches a certain speed. Checking the owner's manual for settings and troubleshooting steps is a good start. If the problem persists, consulting a qualified mechanic or dealership for diagnosis and repair is recommended.
