Why can't the right rear door of the Regal be opened from the inside?

It is likely a child lock issue. 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. It could also be due to a damaged internal lock mechanism, in which case replacing the lock block would solve the problem. Alternatively, the return spring on the lock block might have fallen off; in this case, remove the door panel and reinstall the spring. Below is some relevant information about child locks: 1. Introduction: Child locks are a safety feature designed to prevent children from accidentally opening car doors and causing harm to themselves. 2. Function: When children are seated in the rear, the child lock prevents them from opening the door during travel, thus avoiding potential dangers. This ensures that the door can only be opened from the outside by an adult after the vehicle has stopped.
