Frequently Asked Questions - LOCK-150 Steren
How do I set or change the combination on the Steren LOCK-150?
Open the lock completely. Press and hold the reset button located on the side of the body. Dial your new 3-digit code, release the reset button, and scramble the wheels. Test the new combination before closing the lock.
I forgot my code. Can I recover it?
The LOCK-150 is a mechanical padlock, so there is no electronic recovery. If you are unable to guess the code, you can try each combination from 000 to 999. Otherwise, contact Steren authorized service for assistance. Do not use force.
Can the lock be used outdoors?
The body is corrosion-resistant, but it is not completely waterproof. For outdoor exposure, install it under a covered area or use a weatherproof lock cover. Periodically apply graphite to the moving parts to prevent rust.
How should I clean and lubricate the lock?
Wipe the exterior with a dry cloth. Use a small amount of graphite powder in the keyway or around the shackle and dials. Avoid oil lubricants because they collect dust and can make the dials stiff.
Does the LOCK-150 need a battery or power source?
No. It is a fully mechanical combination lock. It has no battery, no wires, and no electronic components, so it works anywhere and never needs charging.
What tools do I need to install the lock?
No tools are needed for the padlock itself. The LOCK-150 is portable. If you mount it on a door or locker, you only need a hasp or staple (not included) with standard 5 mm screws.
Why are the dials jammed and how can I fix them?
Jamming is usually caused by dirt or corrosion. Gently turn each dial one at a time while pulling the body slightly. If that fails, apply graphite powder. Never force the shackle, as this can permanently damage the mechanism.
Can I use this lock for my gym locker or school bag?
Yes, the compact size and 6.35 mm shackle make it suitable for most lockers, hasps, suitcases, and toolboxes. Make sure the shackle diameter fits the hasp hole before use.
What is the warranty period for the Steren LOCK-150?
Steren offers a 1-year limited warranty against factory defects. Keep your purchase receipt. For warranty claims, contact the Steren store or authorized service center where you bought the product.
