What is a car door does not open inspection?

As you might have guessed, a door that won’t open is a problematic door. When you bring your car to the repair shop, a mechanic will inspect the door mechanism in order to figure out the problem and repair it.
Car doors don’t just magically open—a group of cables and rods within the body of the door attach the inner and outer door handles to a latching mechanism. The door lock is usually tied to this mechanism with a rod as well.
When you pull the inner or outer handle to open a car door, the following happens in quick succession (usually without a thought spared for the brilliant door engineers who toil day and night to ensure you can get in and out of a car so easily):
  • Upon a door handle being pulled, a cable-connected rod moves and trips the door latch mechanism
  • The latch unhooks from a metal clasp securing it within the doorframe
  • With latch unhooked, you can easily push or pull the door open
As you can see, car doors are more complicated than they might look. That’s why you’ll need an inspection when something goes wrong.

What happens during an inspection for a door that won’t open?

On first inspection, your mechanic will look at the following components for any obvious issues:
  • Door lock
  • Latch
  • Catch mechanism
The inner and outer door handles will be examined, and your mechanic will likely have to remove the door to closely inspect the lock mechanism and get a better understanding of the problem, if it isn’t easily fixable.
Upon closer inspection, your mechanic will likely determine that one of the following issues is responsible for your car door not being able to open:
  • Damaged rod or handle cable: The cable or rod connecting the door to the frame’s latch assembly may be loose, damaged, or broken—if this is the case, you’ll likely notice that the handle offers no resistance when you pull it to open the door.
  • Damage to door latch assembly: A battered latch assembly will definitely impact your ability to open the door.
  • Loosened latch screw: These can come loose and get lodged in the inner door frame, and the door won’t open.

Do I need to fix a car door that won’t open?

Well, beyond the obvious (to get into or out of your car), it is essential that your car has properly functioning doors. Not only do they allow easy entrance to and from your vehicle, but car doors also protect you and your passengers from debris, inclement weather, or—heaven forbid—falling out of the vehicle.
If your car door won’t open for any reason, get a trusted mechanic to fix the issue as soon as possible.
