What to Do When the Car Door Won't Open?
1 Answers
Classification of car door failure to open: 1. All four doors won't open: This is most likely because the driver has activated the central locking system. In most car models, the central lock automatically disengages when the vehicle speed exceeds 15 km/h. The purpose of the central lock is to prevent passengers from accidentally opening doors while the vehicle is in motion, thereby avoiding potential accidents. In this case, simply have the driver deactivate the central lock or manually pull the mechanical lock pin on any door to open it. 2. Rear doors won't open: If the rear doors remain unopenable even with the central lock disengaged, the only possible reason is that the child safety lock is engaged. Only rear doors are equipped with child safety locks, while front doors can only be opened using the interior handle or mechanical unlocking. 3. Remote key won't open doors: There are two main reasons for remote key failure: issues with the remote or RF transmitter, or problems with the main unit or door control module. First, check if the remote has sufficient battery power and replace if necessary. If battery isn't the issue, test other buttons on the remote (e.g., trunk release). If other buttons work normally, the problem lies with the door control module. When the remote key fails, mechanical key can be used temporarily - most car models unlock by turning clockwise and lock by turning counterclockwise. 4. Mechanical key won't open doors: If even the mechanical key fails to open the door, this typically indicates door lock mechanism damage. Normally, mechanical keys should work when used correctly. In case of door lock damage, contact a 4S dealership or professional repair shop for assistance.
