How do car door locks work?
We all know how car door locks operate, to an extent: depending on the make and model of your vehicle, you use either the ignition key or a remote fob to unlock it. For all car door locks, there are a series of metal control rods within the door that are attached to the latch and handle, as well as a knob: the plastic part that sticks out of the top of the car door, and physically reflects the latch moving up or down.
In the case of a power lock system, the mechanics consist of an actuator and a latch. The actuator is the electrical component that powers the automatic locking/unlocking of the car door. Rods connect the actuator to the latch; when the actuator moves the latch upwards, it connects to the outside handle via the anchor and opens the door. When the latch moves downwards, the outside handle is disconnected and therefore locks the car.
Car door locks are made vulnerable by exposure to extreme elements like the wind and rain. Dirt and water can get into the lock and corrode its internal parts; further, the repeated use of the lock mechanism generates natural wear and tear over time.
How do I know when my car door lock is not working properly?
It will be pretty obvious when your car door lock is malfunctioning. If your power door lock is experiencing problems, it’s likely an issue with the actuator. Below are a list of red flags, and what they mean.
Problems with the actuator:
from within the car door
This is one of the earliest symptoms of lock trouble, and flags a potential issue with the actuator. While it’s common for actuators to make steady, subtle whirring noises when they are being used, more pronounced and jarring sounds could indicate malfunctioning actuator gears.
locks behaving unpredictably
Intermittent function suggests that your actuator has some internal wiring issues.
locks not working at all
If you’re at the point where your power door locks are entirely unresponsive, there is a serious issue with the actuator: the door lock system will shut down when the actuator has failed.
Problems with the latch:
not stay closed
In this instance, the latch mechanism is unable to attach itself to the anchor, resulting in a door that remains open.
to be slammed shut to close successfully
You shouldn’t have to force your car door closed to have the latch mechanism work. This means that the latch and anchor are misaligned, or the latch is simply not working as it should. If you continue to slam the door shut, the latch mechanism will fail entirely and require replacement.
A stuck door indicates that the internal latch mechanism has failed, and needs to be replaced.
What does car door lock repair entail?
In the event that your car door lock requires repairs, the process is relatively straightforward for all vehicle makes and models.
Generally, a mechanic will remove the affected door panel/panels and raise the window, then gradually remove the required parts: the inner door liner, the door handle control rod, the lock control rod, and remove the outdoor door handle. Then the lock itself can be accessed, and damaged parts, or entire mechanism, can be replaced.
How much does car door lock repair cost?
Car door lock repair is a relatively quick and painless process, and the prices aren’t that egregious either. An assessment and repair of your car door lock can cost anywhere from $50 to $300, depending on the extent of the damage and the amount of labour it will require.
Many car door lock repairs do not require new parts, and can be remedied by a qualified technician accessing the internal system and correctly reconfiguring the system. In these cases, a consultation for a standard car costs between $175 and $225, and for luxury vehicles $275 to $325.
Actuator replacement, on the other hand, should cost between $200 and $300 per door, factoring in the cost of the part and the labour required.
The ability to easily get in and out of your car is a must for any driver, and a functional door lock is a fundamental part of that process. Don’t leave it to the last minute—use our quick quotes service today to find the best technicians in your area.
