Causes of car locks malfunction
Contents
Before looking into each of the causes of a failed car lock, it is essential to understand the flaws found in a vehicle’s ignition system. While central locking systems are a boon to the modern world, making it easier to lock and unlock all vehicles at once, their centrality is also an issue. , it is still localized as a one-stop shop. When a single electrical system controls multiple locks, the entire system will function if a single component is misplaced. So normally, if there’s a problem with the ignition, it affects every lock on the vehicle. Some common causes of electric lock problems include:
Broken lock actuator
The vehicle’s locking actuator converts an electrical signal into mechanical motion. In short, it reads electrical signals from the vehicle and responds by locking or unlocking the vehicle. Transmissions containing wires and gears wear out over time and need to be replaced in used vehicles. Signs that actuators are working include strange, loud noises coming from locks as they operate, erratic locking and unlocking, and complete failure of the power lock. The replacement requires disassembling the car door.
Electric fuse blown
A car’s central locking system contains a large amount of wiring. Like home electrical systems, cars use fuses to protect the vehicle’s electrical components. When the circuit is overloaded with too much electricity, the fuse blows, protecting the vehicle from severe damage. Generally, a mechanic must replace a blown fuse.

A system of wires that conducts current from a car battery to activate the mechanical functions of the lock. When wires become worn and frayed, the electrical signal is disrupted, resulting in faulty locks that can lock or unlock themselves or stop working. Working with wire is a risky business. If you suspect wire damage is to blame for your lock problems, have a mechanic investigate.
Damaged solenoid
Some car locks have a component called solenoid that is similar to the actuator. The solenoid is a magnetic component that controls the latch of the lock. The solenoid pulls the latch back to the door when you press “unlock” and latches when you press the door’s “lock” button or latch. A damaged solenoid will not latch or unlock the door properly, resulting in a jammed lock or a door handle that won’t open the door. Solenoids require professional replacement. The solenoid is located inside the car door and replacement or repair requires disassembling the door.
Key fob is broken
