How to Solve ESCL Unlock Failure?

ESCL unlock failure can be resolved by: The issue of unlock failure is usually caused by low battery voltage, simply recharge the battery; Alternatively, turn the steering wheel to full lock, then center it, and restart the vehicle. ESCL stands for Electronic Steering Column Lock in automobiles. The electronic steering column lock is an electronic device used to secure the steering column, installed below the steering wheel system as part of the vehicle's anti-theft system. This module determines the required actions based on the driver's intent, vehicle speed, and the status of the steering shaft lock, using a latch system to lock and unlock the steering column to protect the vehicle's security. The steering column lock is a steering column locking device, including: a key switch module that generates a detection signal when the car key or portable terminal is inserted or removed; an owner authentication module that performs authentication steps for the inserted or removed car key or portable terminal based on the detection signal from the aforementioned key switch module; and a locking plate that physically restricts the rotational movement of the steering shaft.
From my experience dealing with ESCL unlock failures, I just encountered a similar situation, and it's probably because the key's battery is dead. I remember that time when I parked in an underground parking lot, and the unlock function didn't respond at all. I guessed it was due to strong electromagnetic interference, with metal structures or nearby electronic devices affecting signal transmission. The solution is simple: first, try replacing the battery. You can find button batteries at regular supermarkets, but make sure the model matches the key's manual. If that doesn't work, stand closer or try a different position, as sometimes the car body blocks the signal. I recommend using the physical key for emergency unlocking, and don't forget to set the anti-theft lock before opening the car door. Regular maintenance of the key, keeping it clean, and avoiding moisture or impacts can reduce such issues. If the problem persists, visit a professional auto shop for a diagnostic check—don't attempt to disassemble it yourself.
