If you hear a rumble or an unexpected 'rat-atat-a -tat' locking or unlocking your car door It could be the time to replace the actuator. Based on the brand and model of your vehicle, this could require partial disassembly of the inner door panel.

Loose or Broken Locks
It could be that the mechanism for the latch is loose or disconnected rods. These rods can bind or rust, preventing the door handle from engaging the latch and allowing the door to be opened with hand. It's important to inspect the rods and their connections thoroughly prior replacing them. You'll need access to one of your other doors in your vehicle to examine the linkage that connects the latch to the handle.
A locked that is jammed can be lubricated. If the key isn't turning or the handle is stiff to the touch, try applying lubricant to the lock mechanisms and wiggling it around until it feels smooth. If this doesn't solve the issue, you can try covering the key with the lubricant before sliding it into and out of the lock to loosen the tumblers inside.
Rust and debris can also cause obstruction to the lock mechanism or prevent the key from turning inside it. A thorough cleaning of the lock mechanism and keyhole can remove the obstructions and allow the lock to function properly once again.
Another issue that can be encountered when locking and unlocking cars is a fuse that is blown and connects to the power lock system. Over time, high voltage could destroy these fuses, causing them to stop working. If you know what to do, it is easy to pinpoint the issue and repair it.
Damaged or missing components are more serious issues that require a professional repair. If the latch or lock cylinder are damaged, they'll need to be replaced. This will require removal of the door's panel and disconnecting the rods and cables. The lock actuator must be removed as well. This is a more complicated repair, but it is feasible for amateur mechanics.
After the replacement process is completed and the lock cylinder is installed, you can put in the new lock cylinder and check it for proper operation. If your vehicle is equipped with a deadlock feature, make sure you follow the manufacturer's instructions for disengaging it before using the door once more. If you aren't confident completing these steps on your own, consult your local Nissan service center for assistance.
Locks damaged by damage
A car door lock that isn't remain open or open at all can be a major safety risk. If it opens while driving it could cause you to lose control of your vehicle and even cause an accident. If the lock is shut and not activated by your car key, thieves could steal your vehicle. It's crucial to understand how you can repair a damaged door lock.
The most frequent problems with car door locks result from wear and tear or lack of maintenance. These issues can cause the door handle to not latch or open properly, or even get stuck within the lock. These issues could lead to more damage and a high repair bill if not taken care of.
To prevent these problems You should regularly inspect and clean your door lock. Cleaning the lock cylinders, tumblers and latches can help keep them clean and free of grime and dirt. You should also lubricate the locking mechanism to ensure that it works smoothly.

You can also apply a lubricant in order to keep the locking mechanisms free of dirt, debris, and make them easier to turn.
Broken Latch
A broken latch could be the reason why you can't close your car door. These mechanical assemblies are made of heavy steel hooks that depend on torsionsprings and pivots and precisely milled metal notch to function properly. In time, the repeated usage can cause wear and tear on these components, which can cause issues with the door's ability to lock. This problem can also be due to exposure to extreme weather conditions such as salt and rain. These elements can cause corrosion to metal and cause it weaken.
If your latch is not retracting even after you've tried pushing manually it back, the issue may be something as simple as an absence of lubrication. Check the latch to be sure that it's not blocked by dirt, rust or other debris. If you do not find any obstructions spray WD-40 or lock deicer through the keyhole. This will loosen the jaws and they can be retracted easily.
Using the same method, you can also apply lubricant in the form of liquids to the hinge pins and latch case to help it move around freely. If none of these methods work, you will need to remove the entire latch assembly in order to inspect all the parts.
It's also possible that the strike plate that is attached to the frame isn't aligned with the latch, which can hinder it from retracting. In this scenario you'll have to loosen the screws that hold the striker plate in place and shift it slightly to correct the issue.
Adjusting the latch can also fix the latch that is not in the correct position. Find the opening or gap toward the edge of the door where the latch resides, and insert a thin tool, such as a coat hanger, into the opening. To reset the latch simply pull the tool up and down. After you've reset your latch, you should be able to open and close your door easily. If not, you should contact a professional to have the issue fixed.

The exact procedure for removing the door panel is different for each vehicles, but the basic idea is the same: locate all the hardware that holds the handle plate or door panel in place, and then remove it.

Once you have removed your interior handle plate or door panel close the window completely and use needle-nose pliers to take off the rod from the door latch.
