JOUNJIP Single-Sided Keyless Lever Handle Lock - Easy Install

Our review of the JOUNJIP single-sided keyless lever handle finds it most valuable for homeowners or small businesses that want a simple, mechanical entry solution without batteries or keys. The lock's biggest selling point is its fully mechanical 14-button keypad that supports over 3500 combinations, offering reliable keyless access and a temporary passage mode for events. Installation is straightforward thanks to the new square spindle design, and the satin chrome finish makes it look at home on residential and light commercial doors.

Key Features

• Square Spindle Design: Makes installation smoother and improves long-term durability compared with a flat spindle setup.
• Mechanical Keyless Operation: No batteries or wiring required, so the lock continues to work during power outages and needs no electronic maintenance.
• 3500+ Combinations: A 14-button keypad and drop pin code design let users set codes up to 9 digits long and confuse unauthorized entrants.
• Passage Mode Option: Temporarily deactivates the code so guests can enter freely without changing the main passcode.
• All Season Usability: Suitable for entry doors, gates, fences, garage and side entries in typical outdoor conditions (not marine grade).

Who It's For

The lock is best for renters, homeowners, and small business owners who want a low-maintenance, keyless entry that does not depend on batteries or electricity. It fits standard door thicknesses from 35-60mm (1 3/8 in - 2 3/8 in) and is a good match for exterior and interior doors where mechanical reliability and easy code changes matter.

Those who need a lock for custom-thick doors beyond 2 3/8 in up to 4 in should plan to use the compatible SQ spindle extension kit or JOUNJIP metal gate box GB2020. It is not intended for marine environments or heavy commercial security scenarios where electronic logging or remote control is required.
