Car Latch Problems: 9 Most-Common Issues (Solved)

I’ve personally tried to be locked out of my car with a faulty latch. That’s SO frustrating. Let’s dive into some issues and solutions.

Here are the most common problems and solutions for faulty car latches.

Let’s dive in.

5 Reasons Car Latch Won’t Close

Stuck Latch

A common reason for car door latch problems is a stuck latch. The latch is the mechanism on the back of the door designed to clamp down on the striker plate when the door closes. If it becomes stuck or jammed, the door won’t close properly.

This issue can be caused by dirt, debris, or rust buildup in the latch mechanism.

To fix this problem, you can try spraying some lubricant such as WD-40 on the latch, wait a few minutes, and then clean the grime using a rag.

Accidentally Closed Latch

Another issue that can prevent a car door from closing is an accidentally closed latch. This happens when the latch closes while the door is open, preventing it from securing onto the striker plate.

The solution to this problem is to use a screwdriver or a similar tool to manually lift the latch and revert it to the open position.

Misaligned Door

A misaligned door or striker plate can also cause car door latch problems. If the door or the striker plate are not correctly lined up, the latch may not be able to engage properly.

To resolve this issue, you can try adjusting the striker plate or the door hinges to realign them.

Worn or Damaged Latch Components

Over time, the various components of a car door latch, such as the springs and the locking mechanism, can wear out or become damaged.

When this occurs, the latch may not be able to hold the door closed securely. In these cases, it may be necessary to replace the faulty components or the entire latch assembly to resolve the problem.

Damaged or Worn Weatherstripping

Weatherstripping around the door frame can wear out or become damaged, making it difficult for the door to close securely.

If the weatherstripping is damaged, you may need to replace it to ensure a proper seal and allow the door latch to function correctly.

5 Reasons Car Latch Won’t Open

Stuck Latch

A common issue with car door latches is that they can get stuck, making it difficult to open the door. This can be caused by a variety of factors, such as dirt, debris, or rust buildup within the latch mechanism.

Addressing this issue will typically involve cleaning and lubricating the latch to ensure smooth operation.

Broken Handle Cable

Another reason why a car door latch might not open is due to a broken handle cable.

This cable connects the door handle to the latch mechanism, allowing the door to open when the handle is pulled. If this cable is damaged or broken, it will be unable to transmit the necessary force to open the latch. Replacement of the broken cable is necessary to resolve this issue.


Rust can accumulate in and around the latch mechanism over time, especially in areas with high humidity or exposure to salt. This can impede the proper functioning of the latch, making it harder to open the door.

Treating the rust and maintaining the appropriate level of lubrication is important to prevent this problem from worsening.


Sometimes, the latch can become misaligned with the door striker, preventing the door from opening properly.

This can result from door hinge wear, vehicle collisions, or other factors that affect the proper alignment of the latch and striker. Correcting this issue will typically involve adjusting the latch or door to restore proper alignment.

Electrical Malfunction

In some cases, the problem with a car door latch might be attributed to an electrical malfunction. This is more likely to occur in cars with electronic door locking systems.

Diagnosing and fixing electrical issues often requires the expertise of a qualified mechanic.

Other Car Latch Problems

Car door latch problems can arise from various factors. From wear and tear to external damage or mechanical issues, these problems can compromise vehicle safety and pose challenges to drivers. Here are some common car latch problems:

  • Rusted or corroded latch: Exposure to humidity, rain, or road salt can cause the latch to rust or become corroded. This corrosion can prevent the latch from functioning properly, and in some cases, may require replacement.
  • Broken or worn-down latch components: The internal components of a latch can wear down or break over time. When this occurs, the door may become difficult to close, or it may not stay closed at all. Replacing the damaged components or the entire latch assembly is usually necessary.
  • Faulty lock actuator: A door lock actuator is an electronic component responsible for locking and unlocking the door latch. If the actuator fails, it can result in the door remaining locked or, conversely, not locking at all. Replacing the faulty actuator is essential for restoring the door’s locking functionality.
  • Damaged door handle or linkage: If the door handle or linkage becomes damaged, it can prevent the latch from properly releasing. This can lead to the door being stuck either open or closed, and in some cases, it may be necessary to replace the handle or linkage components.

It’s essential to address these car latch problems promptly to ensure the safety and security of the vehicle and its occupants. Regular maintenance and inspection of the door latch assembly can help prevent these problems and keep the door functioning correctly.
