If the door latch doesn’t spring back, it may be due to misalignment; you’ll need to adjust the position of the latch relative to the latch plate. Use a tool like a screwdriver to gently nudge the latch, then close the door to test it until it fits properly.

Rust on the latch hook can also prevent the door latch from springing back. You can purchase a bottle of rust remover or grease to remove the rust. Apply it evenly to the interior latch hook and latch, then repeatedly open and close the door to ensure even lubrication. Additionally, if the interior latch hook is misaligned, the entire door may need adjustment; it is recommended to have it inspected and repaired at a repair shop or dealership.

If the issue of the door latch not springing back persists after reviewing the above causes, you should promptly visit a repair shop or dealership for a detailed inspection to identify and resolve the problem. Many new cars may also experience issues where the door latch fails to spring back or the door is difficult to close due to high-quality weatherstripping and airtight seals.

If you notice that the door latch is not springing back, you can first try using the spare mechanical key. Generally, a mechanical key is hidden inside the remote key fob. Owners should develop the habit of instinctively pulling on the door handle after locking the car to check that all doors are securely locked, thereby avoiding unnecessary property loss due to carelessness.
