Frequently asked questions
How secure are OTTOLOCK locks against theft?
OTTOLOCK locks are built with a rigid stainless steel band or shackle wrapped in a durable outer sleeve, engineered to resist cutting, prying, and bolt-cutter attacks far better than cable locks. For high-crime areas or overnight parking, we recommend pairing your OTTOLOCK with a second lock (like the SIDEKICK U-Lock) for layered protection.
Do OTTOLOCK locks use a key or a combination?
All OTTOLOCK locks use a resettable 3-digit combination — no key to lose, no fumbling in the dark. You can set your own custom code out of the box and change it anytime, making it easy to share access or reset security if needed.
What size OTTOLOCK do I need for my bike, e-bike, or gear?
Lock size depends on what you're securing — a frame, wheel, e-bike battery, or gear bundle all call for different lengths. Use our Size Selector quiz to get a personalized recommendation in under 60 seconds, or check the sizing guide on each product page.
Are OTTOLOCK locks weatherproof and durable outdoors?
Yes — OTTOLOCK locks are built to handle rain, mud, snow, and daily outdoor abuse without rusting or seizing up. The combination dial and locking mechanism are designed to keep working reliably in all weather conditions, year-round.
How do I reset or change my OTTOLOCK combination?
Resetting your combination takes seconds: align the dials to your current code, use the reset pin to set a new one, and you're done. Full step-by-step instructions are available on our Support page for every lock model.
Where are OTTOLOCK locks made, and what's the warranty?
OTTOLOCK locks are designed and made in the USA, built to hold up to daily commuting and outdoor use. Every lock is backed by our manufacturer's warranty — details and coverage terms are on our Warranty & Policies page.
