The reasons why the left rear door of BMW X5 cannot be opened from the inside are as follows: Child lock issue: Solution: First open the door from the outside, then locate the child lock switch on the side of the door and set it to the off position. Lock mechanism problem: Solution: It could be due to a damaged internal lock mechanism - replace it with a new one; or the return spring on the lock mechanism may have fallen off - remove the door panel and reinstall the spring. Function of child lock: The child lock is a safety feature designed to prevent children from accidentally opening car doors and getting injured. Its purpose is to prevent active and unaware children from opening doors during driving when seated in the rear seats, thereby avoiding potential dangers.
