What is a door latch?
A car door latch’s job is pretty straightforward: when you open your car door, the door latch releases, and when you pull it shut, the latch makes sure your door stays secured in place.
Why it matters: Simple as a door latch may be, its job is pretty important. Your door latch keeps you safe by ensuring your door remains securely closed while your vehicle is moving—and that you can exit your vehicle quickly in case of an emergency.
When should I replace the door latch on my car?
If your car’s door latch is broken, you’ll probably notice it relatively quickly. Here are the main signs of a failed car door latch:
Your door won't open or close properly: A car door that’s stuck shut or won’t stay closed is one of the most obvious signs of a failed door latch—but this could be linked to other problems, too. A mechanic can confirm whether a broken door latch is the culprit in your case.
Your door is more difficult to open or close: If you find yourself having to use a little more muscle power to open or close your car door, your door latch may be damaged or worn out.
How often should a door latch be replaced?
In many cases, a car door latch will last the life of a vehicle. But a broken door latch is a fairly common issue for drivers—especially those with older vehicles or those subject to more wear and tear.
The only time you’ll need to replace a car door latch is if it wears down or breaks early.
If your car is still under warranty when your door latch breaks, you may want to take it to your dealership’s service center to save on your automotive repair costs.
Can I replace my door latch myself?
Drivers with enough technical know-how may be able to replace a car door latch. But some door latch mechanisms can be more complicated than others—and if you don’t feel comfortable taking care of the repair yourself, it’s best to have a professional mechanic do so for you.
