د خ ل to enter is used for a closed environment e.g., to enter a house, a hole, a tent etc. From where you can exit خ ر ج from the same entrance/door etc.
While س ل ک is used for an open path, way, road etc. Which may have several exits or turns. To Enter might not be the exact English subritute for س ل ک.
Peace!
