Modern car locks employ a pin and tumbler mechanism that works by having the ridges of a key align with the pins of a lock the cylinder to trigger a shear line that opens the latch mechanism to allow entry. Rekeying involves changing the pin and tumbler configuration to match a different key while preserving the proper alignment of shear lines. This prevents unauthorized key usage. The cylinder of the lock may incorporate built-in security features, such as anti-drill and anti-pick pins to discourage break-in attempts.

Replacement
The door lock actuator is a crucial element that controls the electric locks that are found on the majority of cars. When they are operating properly, they will retract and then engage the latch when you press the button on your key fob or inside your vehicle to lock or unlock it. If you're having issues with your power locks, it might be time to replace the door lock actuator.
The actuator is electric and could fail due to corrosion from moisture, dust, and other contaminants that are introduced into the components. Door lock actuators can also fail prematurely if physically damaged due to an accident or a failed attempt to jimper the lock open. Poor quality components can also cause the door lock actuator to fail prematurely or even completely.
The door locks will not respond to the key fob or buttons on the vehicle in the event that they're not responding in a consistent manner. Another symptom is when you attempt to activate the lock and it produces a rattling or buzzing sound.
Replacing an actuator for a door lock is a simple job that most auto shops can do in just one or two hours. The door panel, window, the inner door liner, and the rods for control of the lock need to be removed. The lock rods and electrical wiring will also have to be disconnected. Installing the new actuator into the door is the next step. They will then connect the rods, cable and replace any damaged clips.
A replacement door lock actuator is priced between $125 and $225, depending on the model and make of your vehicle. You'll require a few cheap tools to complete the repair if opt to tackle it yourself. You'll require an instrument to remove the door handle for crank windows (about seven dollars from any automotive parts store) as well as an offset flat-blade screwdriver. When replacing the power locking actuator, it's important not to reuse the old latch rod or cable for the door lock. This could cause the new lock to fail.
Repair
Modern vehicles come with power door locks controlled by actuators. These are more complex than the simple mechanical lock cylinders used on older cars, and are more difficult to repair if they become damaged. However, there are plenty of ways to fix them, and they are generally inexpensive. The auto door lock in your car could need replacing due to electrical problems, physical damage or simply wear and tear as time passes.
One common cause of a power door lock that isn't working is an overblown fuse. The doors rely on this fuse to send a signal that activates the motor, which can open or close the door. You can replace the fuse by yourself, and it is fairly cheap. Another possible problem is an actuator that is worn out. An actuator that is not working properly can be identified by a number of indicators, including irregular door lock operation and unusual noises. G28 can test the actuator with an electronic multimeter. If the multimeter shows the actuator is powered, but it doesn't start the power locks the actuator is most likely defective.
The best method to identify the problem with an actuator is to take the door panel and then visually examine it. The actuator is typically located near the handle. It is also possible to play with the lock mechanism by wiggling the lever upwards and downwards when you press the button to lock or unlock the car. If the mechanism isn't cracked or loose, it is probably just jammed. WD-40 is a fantastic solvent to be used to loosen mechanisms. A can of this solvent is available at most home improvement centers and automotive supply stores, and it is relatively affordable. Make sure you make use of a long, thin straw so that you can get the lubricant inside of the lock. If the mechanism is still stuck the penetrating catalyst could be used to reduce corrosion and restore function. If you have tried all these methods and the lock still does not work, it's time to get an expert.
Installation

Many people do not think about their car's door locks until they stop functioning, but the reality is that the doors on your car are one of its most crucial safety features.
The lock on the car door is controlled by a complicated set of mechanics that includes a control rod as well as a latch. Based on the model, these elements could be controlled by the key fob or interior buttons. The body controller sends a signal to the actuator whenever it receives an internal key fob or interior button signal.
A defective actuator can cause your door locks' power to stop working and this is not ideal for security or ease of use. In addition, some modern vehicles integrate their locking systems with other electrical systems, and an unreliable actuator could affect these functions too.
There are several common signs that the door lock actuator in your car is malfunctioning.
Unusual noises and inconsistent operation are typical symptoms of an actuator that is malfunctioning.
