How to Use & Password Management
Initial Setup & Locking
-
Turn the steering wheel approximately 90 degrees to create space.
-
Extend the lock and hook it onto opposite spokes of the steering wheel.
-
Adjust the length to ensure a tight, secure fit.
-
Scramble the dial numbers after locking to prevent unauthorized access.
Unlocking the Device
Simply rotate each of the five dials to your pre-set password combination. The lock will disengage, allowing you to remove it from the steering wheel.
Changing or Resetting the Password
To change the password, you must first unlock the device using the current (old) password. Locate the small code switch lever (usually under a protective cap near the hooks). Slide this lever in the opposite direction, set your new custom password by aligning the numbers with the matching line, and then slide the lever back to its original position. The factory default password is often set to 00000.
Forgot Password? If you forget your custom password and cannot unlock the device, your options are limited. Try to recall any significant numbers you may have used. If unsuccessful, you may need to contact a professional locksmith or the supplier for assistance, as the lock cannot be reset without the current password.

Comparative Analysis
Compared to traditional T-bar locks or disc locks (Disklok), the Zhenzhi retractable lock offers a balance between security and convenience. While full-cover locks like the Disklok provide superior physical protection, they are often heavier and more cumbersome. The Zhenzhi model's keyless feature gives it an edge over many basic steering wheel locks that rely on physical keys, which can be lost or copied.
