Failure to open the rear door of a car is a common problem that can be caused by a variety of reasons. Here are some common solutions:
Check and close the child lock
Child locks are one of the main reasons why the back door cannot be opened from the inside. Check if there is a child lock switch on the side of the door and flip it to the unlocked position to resolve the problem.
Turn off the central lock
If the central lock is open, the rear door may not open. Press the central control switch on the main driver control panel, close the central control lock and try to open the rear door.
Check door locks and handlebars
Damage to the door lock or handle may also prevent the rear door from opening. Check whether the lock core, lock body and handle are working properly, and repair or replace if necessary.
Check the electric control system
Modern car door locks are usually associated with electronic control systems. If the electronic control system fails, try to restart the car power supply or contact a professional maintenance personnel to check.
Lubricate door hinges and locks
Rusty door hinges or latches may prevent doors from opening. Apply the appropriate lubricant to the door hinge and latch to check that it can be opened and closed smoothly.
Check the internal structure of the door
