Why Do My Khybers Power Door Locks Only Work Sometimes?

I installed aftermarket power door locks in my Suzuki Khyber, and they work fine one moment but randomly stop responding. Sometimes they lock but don’t unlock, o r vice versa. Is this a wiring fault, weak actuator, o r something else? What do most Khyber users face in this case?

Intermittent functioning of power door locks is a common issue in cars with aftermarket central locking, especially older models like the Khyber.

Common Causes:

Loose Wiring/Connectors: Over time, wires inside the door panels can become loose o r corroded. Since the Khyber wasn’t built for power locks, the installation often involves makeshift wiring, which can become unreliable.

Weak Actuators: The lock actuators the motors that move the lock rod may wear out o r become sluggish, especially if cheap brands are used.

Weak Battery o r Voltage : If the car battery is weak o r theres voltage fluctuation, actuators may not get enough power to operate reliably.

Faulty Control Box Brain Unit: The central control unit that manages the locks may be malfunctioning o r have a bad connection.

Fix: Inspect all door wiring for looseness, clean terminals, and test the actuators individually. If the problem is widespread, consider replacing the central locking module with a better-quality one.
