The door latch can become stuck or even break requiring repair or replacement. Replacing the door latch is a simple task if you use a gentle touch and patience.

You will have to remove the door panel to do so. Refer to the article that describes a step-by-step process to replace the door panel.

Before you do any work on your car it is important that you wear safety glasses, work gloves and dispose of all fluids in a safe manner. Coolant is poisonous and should be treated as such. Animals and small children have been known to die from ingesting coolant. If you have to jack up your car, make sure to use jack stands and chock your wheels as well as applying the parking brake. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability. Always wear eye and hand protection. Disconnect the battery before working on your car.

In order to remove the door latch, you will first have to remove two Phillips screws on the inside of the doorjamb.
