If your 2009 hyundai elantra has problems locking or unlocking its doors, there’s likely an issue with the door lock actuator. This mechanism is responsible for allowing your car’s locks to work when you push a button on the key ring or remote.
When the actuator fails, you may experience the following symptoms:
Door Lock Actuator
The Door Lock Actuator is the part of your power door locks that triggers when you press a button to lock or unlock. The motor of the actuator powers a set of gears that turn the mechanical linkage used to lock or unlock the doors of your vehicle. This system is designed to be extremely simple and safe. The motor of the actuator is powered by a small battery. The system receives signals to lock or unlock the doors from a variety of sources, including the key remote fob, the door locks themselves and sometimes from an OnStar signal.
When the motor in the door lock actuator fails, it may cause your doors to only lock or unlock sporadically. Or, the doors will make an unusual noise while they are locked and unlocked. If you’re experiencing any of these symptoms, it may be time for a replacement. The cost of a replacement door lock actuator is dependent on your specific model and year, as well as where you live.

Door Lock Rod
The door lock rod of the 2009 hyundai elantra is part of the system that locks and unlocks your doors. This component of the vehicle gets used regularly, and as a result, it can wear out quickly. If you notice that your doors don’t lock or unlock properly, or if they make an unusual noise when closing, it may be time for a replacement. This will ensure that your doors stay locked when you aren’t driving, which can help prevent theft and vandalism of your car.

Door Lock Switch
A power door lock switch sends a signal to a small motor that turns gears that lock and unlock the doors. If the switch or actuator isn’t working, you may experience doors that won’t lock or unlock properly or security & alarm systems that malfunction.
A blown fuse is another common problem that can lead to a power door lock switch or actuator malfunctioning. A fuse is a low resistance resistor that converts large amounts of electrical current into smaller, more manageable ones.
If your fuses blow, the electrical current won’t run to the power door lock actuator and it will stop working. This can cause the system to be inoperable, so it’s important to check them regularly and replace them when necessary.
